Cord Blood Cures Baby’s Grapefruit-Sized Tumor

 Jamie Page and her husband, Ben, discussed the issue of banking their newborn’s cord blood so frequently before the birth that they finally decided if they didn’t do it, it might be the biggest regret they ever had.

“Medical advances change so quickly. Who knows when this child is 10, 20 years old if she’ll need it,” Page said. “It’s a great medical backup to have.”

It turns out the Pages, who live in Schaumburg, Ill., were absolutely right to save the cord blood.
Page had a normal pregnancy and her daughter, Harlow, was born seemingly healthy on March 19, 2008. But after two weeks, the Pages noticed she was crying a lot and seemed uncomfortable – and it just got worse.

“We were told it was probably just colic, to try different formulas, different ways of putting her to bed,” Page said. “At first I thought they were right. We must have tried six or seven different types of formula and we put gas drops in it, but she was pulling at her stomach . . . I just couldn’t put my finger on what it was.”

When Harlow was just 3 months old, her stomach became distended and she stopped having wet diapers. The Pages ended up in the emergency room, and tests revealed every parent’s worst nightmare: A grapefruit-sized mass was blocking Harlow’s kidney. Doctors quickly inserted a catheter and did a biopsy, which was sent out to several pathologists across the country.

“We were in the hospital for five or six days, letting her kidneys recover, and it was the craziest thing,” Jamie Page said. “In two days, we got four different pathologies – they all had different diagnoses. It resembled different cancers, but nothing they had ever seen before.”

There were no answers for the Pages – doctors didn’t know how to treat Harlow’s cancers, or what her prognosis was. A few pediatric oncologists in nearby Chicago decided it resembled a rare brain cancer, and it should be treated as such – so chemotherapy was the best protocol.

“We were so scared,” Page said. “My dad went through chemo for lung cancer, and it made him much more sick than helping him, we didn’t want to torture her. We just wanted her to be comfortable. At the time, doctors said she only had a few weeks to a few months to live.”

Ultimately, it was Harlow who decided for her parents. Her smile, despite how sick she was, made her parents think, ‘How can we not give this little girl a chance to fight?’

That’s when the Pages asked their doctors about a stem cell transplant. But the doctors were surprised – few families have their own supply of cord blood, they said, and it’s hard to find a match.
That’s when things started looking up for Harlow Page.

The Future of Medicine

After three rounds of chemotherapy, the doctors decided the tumor had shrunk enough for them to go in and remove it surgically, but when they cut Harlow’s abdomen open, the tumor was completely gone.

“We went in thinking she might’ve needed a hysterectomy,” Page said. “All she had left was scar tissue. They called in more surgeons to make sure they were looking in the right place. We were thrilled.”
Because the tumor was so aggressive, a stem cell transplant made sense – it was Harlow’s best option of ensuring that the tumor did not grow back. Still, she would need a double transplant.

The Pages met with the hospital's stem cell transplant team, which included Alexis Baby, a pediatric nurse practitioner.

“As of right now, there is a good prognosis,” Baby said about Harlow. “As each year passes, there is a big step toward relapse-free survival.”

So after five days of intense chemo – at higher rates than previously given – Harlow’s current cells were killed off. On the sixth day, she rested in an isolation room and on the seventh, they started the infusion. By this time, Harlow was 9 months old.

She spent 25 days in isolation to avoid any germs, but got to go home for two weeks before coming back to the hospital for her second round. Because she didn’t have enough of her own stem cells for that round, doctors had harvested her blood earlier and used that.

“As grueling as it was, she was getting her own stem cells,” Page said. “She didn’t need to be on anti-rejection pills like other kids. Some families had to worry about host vs. graft disease. We had enough concerns without worrying about her fighting her own body.”

Cord blood stem cells that are saved at birth are collected from the baby’s umbilical cord with a syringe – and the child does not feel a thing, unlike painful bone marrow extractions. Parents send the cells to a cord blood bank of their choice, where the cells can be stored indefinitely.

The price for banking cord blood varies depending on the company, but the procedure costs around $2,000 to $3,000 (this depends on whether or not you've saved the baby's cord blood tissue), plus an annual storage fee of about $125. 

However, if you feel cord blood banking is too expensive an option for you, Baby urges parents to donate their newborn’s cord blood to a public bank, so it can be available for someone else who might need it.

“Otherwise, it's medical waste, and it’s just thrown away,” Baby said. “There is an option to donate it, but a lot of people don’t know about that, so it’s really unfortunate.”

Science has shown that cord blood stem cells are smarter than average cells: Once they are reinfused into the body, the cells migrate to the injured spot and immediately start the healing process.

Other advantages to using cord blood cells – besides not worrying about rejection – include the fact that the cells are younger and have not yet been exposed to any chemical or environmental factors, Baby said.

Doctors are constantly researching how cord blood can treat patients. Studies are being conducted on cord blood stem cells and their effects on brain injuries, Type I diabetes, neurology and cardiology – and that’s just the tipping point. Doctors think cord blood could be the future of medicine.

Harlow was released from the hospital in February 2009 – almost one year after she was born. Her parents had to literally teach her to swallow and eat again, because she had been nauseous for so long and had skipped solid foods. But by June 2009, she stopped taking all medications, and in September of that year, she was allowed to start attending day care.

Harlow has no recollection of being sick, and is a typical 3-year-old: She loves dancing, singing, gymnastics and watching her favorite movie, “101 Dalmatians.”

“I want to encourage other parents to save their child’s cord blood,” Page said. “I tell all our families and friends it’s the cheapest life insurance you’ll ever buy, and it’s an amazing opportunity for your child. To look at her, you’d never know, which is the best part of all.”

Stem Cells Aid Recovery of Heart Size and Function after Myocardial Infarction

By Nancy on March 19, 2011

In a small but extremely significant clinical trial, researchers have reportedly used autologous stem cell injections to help damaged heart tissue recover, reducing the size of enlarged hearts and improving heart function, in people who suffered heart attacks.

Dr. Joshua M. Hare, a professor of medicine and director of the Interdisciplinary Stem Cell Institute at the University of Miami, Miller School of Medicine and his research team, conducted the experimental trial.The research team treated eight men, who had left ventricular dysfunction due to myocardial infarction, at an average of 5.7 years after the episode.

The men were injected with the  Hematopoietic stem cells (HSCs), found in the bone marrow of adults, that was removed from the hip bone of each of the patients.

HSCs are multipotent stem cells that can form all types of blood cell including the myeloid cells, originating in the bone marrow or spinal cord.

Two different types of bone marrow stem cells, mononuclear and mesenchymal cells were injected directly to the damaged part of the heart using a special catheter. The researchers did not observe any significant gains while measuring ejection fractions (EF) in the patients, but cardiac chamber dimensions improved and so did the contractility of the heart.

The function of the heart muscle in the treated area improved in three months, positively affecting the heart contraction function while the infarct size reduced by 18.3% after one year. The enlarged heart reduced by 15 – 20% on an average after a year and the patients tolerated the procedures well, without any serious adverse effects.

The researchers stressed the need for larger trials and detailed study and Hare notes, “We can’t say whether that’ll be in three or seven years down the road. It’s hard to speculate precisely. But we’re talking sometime this decade.”

Stem Cell Recipient Positive Mexican Procedure Working



Ed Johns says he feels like a new man.

The effects of his multiple sclerosis are not as pronounced, something he attributes to a stem cell treatment he underwent in Tijuana, Mexico.

He returned Oct. 13 and has noticed a renewed vitality which increases every day, he said.

Before getting the treatment, merely walking down the stairs was difficult, Johns said. Now he's back to using the personal gym machine in the basement of his North Boulevard home.

Johns, like other Americans, went to Mexico to receive the umbilical cord stem cell treatments because such therapies are not available in the United States.

Before going he was depressed, constantly exhausted and relying on a walker to get around his home. Family members and doctors described his condition as declining.

Despite that diagnosis, Johns' physician, Dr. Thaddeus Aversa, said he was cautious of endorsing stem cells as the answer to multiple sclerosis.

Stem cell research is a new area of science that hasn't been around long enough to know the long-term benefits, Aversa said, prior to Johns' trip.

However, Aversa said, Johns had gone the conventional treatment route with drugs designed to prevent the immune system from attacking nerve cells. Those therapies did not seem to help, the doctor said.

Some scientists say stem cells have the potential to repair damaged cells. However, the federal Food and Drug Administration has not signed off on allowing such treatment in America.

The issue is also clouded by political controversy with many conservatives opposing the use of fetal stem cells for the research.

Researchers are also looking at adult brain stem cells for a possible treatment, according to National Multiple Sclerosis Society spokeswoman Becca Kornfield.

"Currently there is no evidence that stem cells taken from umbilical cords can help replace damaged nervous system tissues," Kornfield wrote in an e-mail. "Clinics that claim to be having success in this arena have not published proof of their work so that the medical community can evaluate their claims."

Aversa said medical journals are often conservative and slow to endorse a new treatment. He said the top medical centers often have different opinions on treatment options for patients.

Johns has not visited his doctor since returning from Mexico, only chiropractors and a masseuse. He was able to verify his payment for the stem cell treatment.

During a recent interview, Johns moved easily with a limp while walking around his kitchen and living room. He relied very little on a small black cane.

He said his balance has returned and he rarely needs to use a support railing when he is in the shower.

"I'm getting ready much quicker," Johns said. "It used to take two to three hours to get ready. Now, it's only one."

Johns' mother said his progress has been a surprise.

"I came home from work and he said he had done a load of laundry, which floored me," Joanne Johns said. "He's just moving better with a better attitude. He takes care of himself and all three dogs during the day."

Joanne Johns flew with her son to Tijuana for the treatment.

"It was pretty good; everybody at the hospital were very professional," Joanne Johns said. "The people down there were just wonderful."

Both said the hospital was smaller than American facilities. The place treats cancer patients with alternative therapies, not chemotherapy. Ed Johns declined to identify the institution at its request.

"It was very clean; the people were amazing," Ed Johns said.

Ed Johns said the doctors started with an IV of saline. As that drained out, they hooked up the first dose of stem cells. Ed Johns described the vial as the size of a triple-A battery.

The procedure ends with three stem cell injections in the back of the neck. The procedure lasts three hours and costs range from $24,000-$28,000.

Ed Johns' son Chris Cahill walked into the basement just as his father was taking another repetition on the machine. The 17-year-old was excited about his father's progress.

"He's getting better slowly but surely," Cahill said. "He's getting better faster than anyone else. It's supposed to take two to three months."

Researchers Find Indirect Path to Attack Breast Cancer Stem Cells

ScienceDaily (Mar. 20, 2011) — Scientists at the University of Michigan Comprehensive Cancer Center have identified a potential new way of attacking breast cancer stem cells, the small number of cells in a tumor that fuel its growth and spread.

 Researchers found that breast cancer stem cells are regulated by a type of cell derived from bone marrow, called mesenchymal stem cells. These cells are drawn from the bone marrow to the cancer and create a "niche" for the cancer stem cells, allowing them to replicate.

"The importance of this is that we may be able to attack breast cancer stem cells indirectly by blocking these signals from the niche," says study author Max S. Wicha, M.D., Distinguished Professor of Oncology and director of the University of Michigan Comprehensive Cancer Center.

Breast cancer stem cells were first identified by Wicha and colleagues at the University of Michigan in 2003. Cancer stem cells are believed to be resistant to current chemotherapies and radiation treatment, which researchers say may be the reason cancer so often returns after treatment.

Little is known about the cancer stem cell niche -- a type of microenvironment that is highly associated with tumor growth and metastasis. The researchers looked at mesenchymal stem cells, which arise in bone marrow. They found that breast cancers in mice sent out signals which attracted mesenchymal stem cells from the bone marrow into the tumor where these cells interacted and stimulated the growth of breast cancer stem cells.

Researchers then identified two signals from a cytokine network -- a type of protein that affects how cells communicate -- that were responsible for stem cell regulation. These same cytokines play a role in inflammation and drugs that block them have already been approved for the treatment of inflammatory diseases such as rheumatoid arthritis. By blocking these cytokine signals, researchers hope that they can successfully target the cancer stem cell population providing a more effective treatment for breast cancer.

Results of the study appear in the Jan. 15 issue of Cancer Research.

Cord blood stem cells used to help cure girl of brain cancer in Spain

Seville, Spain, Mar 8, 2011 / 02:04 pm (CNA/Europa Press).- A four-year-old girl has become the first patient in Spain to recover from brain cancer after being treated with stem cells from her own umbilical cord blood.

The announcement of the girl's recovery came March 7 from the company Crio-Cord, a stem cell bank in Spain.

Alba was born healthy in 2007, but at age two she was diagnosed with a rare form of brain cancer. Her treatment consisted of extracting the majority of the tumor from her brain. She was then given chemotherapy to reduce and eventually eliminate the remainder of the tumor.

Alba's blood system was destroyed during the final round of chemo, thus requiring a transplant of cord blood stem cells.

The procedure was carried out in 2009 by Dr. Luis Madero of the Department of Oncology and Hematology at the Nino Jesus Hospital in Madrid.
Today, four year-old Alba is a healthy girl.

Periodic Reviews
Sixty days after the transplant, Alba was given new stem cells taken from her peripheral blood in order to accelerate the production of platelets. Fourteen months after the transplant, her blood system was completely restored, and she has since enjoyed a normal life.

Dr. Madero called her case unique in Spain. “The use of stem cells to regenerate the blood system is an extended treatment for this form of cancer,” he said. What makes her case unique, he added, “is that for the first time in our country, the stem cells came from a patient’s own umbilical cord, preserved from birth.”

“In recent years, transplants of cord blood stem cells have become increasingly common. In the case of siblings, these stem cells are the best therapeutic option that exists,” he said.

“Our best investment”
Alba’s father, Santiago, who is a computer engineer, and her mother, Teresa, a literature professor, agreed that keeping the blood from Alba’s umbilical cord was the “best investment” they ever made.

Santiago said he had previously seen a report “on the treatment for Parkinson’s using stem cells … and was sympathetic to the idea of using stem cells to treat degenerative diseases.”

“Keeping the umbilical cord is a wager for the future, a life insurance policy that you don’t know if you will need but that could save a life,” Teresa added.

The head of Crio-Cord, Guillermo Munoz, also said he was pleased at the results of the therapy. He noted that the organization was “proud to have participated in Alba’s healing process.”

Cases like these confirm “that umbilical cord blood is an excellent source of stem cells. Being the youngest cells of their kind in the human body, they have great potential to cure,” Munoz explained.

Lawmakers say Conn. cord blood bank moving forward



Hartford, Conn. (WTNH) - State lawmakers say they are hopeful an umbilical cord blood bank system will soon be created in Connecticut, helping to expand a national effort to provide access to valuable stem cells.

North Haven Republican Sen. Len Fasano unveiled legislation Tuesday to set up a public cord blood collection program in Connecticut.

Currently there is just one private cord blood bank in the state. But that means donor families pay a huge fee to access the cord blood for their own use.

"If you have an individual that wants to store the blood, it is certainly their right to be able to do it. But think about its immediate likely uses: If the child develops leukemia, it's from the cells you just banked, you're not going to use those cells," explained Dr. Charles Lockwood, Yale School of Medicine.

Under the proposed plan, parents would have no control over the cord blood donated to the public bank.
"It's not guaranteed you're going to get to use it but you're helping other people and you might get that help in return, if somebody has donated blood. It's about people helping people," said Dr. Winston Campbell, UConn Health Center.

In fact, doctors say there's a one in 20 thousand chance in needing it. But the unique stem cells in a baby's cord blood, usually thrown out at birth, is vital to a number of medical treatments.
"People in Connecticut, who really need a transplant, would have access to cord blood provided by people from all over the country, who have also given their blood to a public bank in that area," said Dr. Edward Snyder, Yale School of Medicine.

That's because the public cord blood bank would be part of a national registry, which also impacts the cost. Instead of millions -- it's down to an initial cost of about $200,000. There are patients who've benefitted from the advances of stem cell research. State Representative Larry Miller used his own stem cells in his fight against multiple myeloma.

"I had a 5 year death sentence and that was 13 years ago. So its, every year is a bonus year for me. There is no cure for cancer," Miller said.

A public hearing is set for Wednesday at 10am before the Public Health Committee at the Legislative Office Building.
