Stem Cells From Hair Follicles May Help ‘Grow’ New Blood Vessels

Tuesday, April 1st, 2008


ScienceDaily (Mar. 29, 2008) — For a rich source of stem cells to be engineered into new blood vessels or skin tissue, clinicians may one day look no further than the hair on their patients’ heads, according to new research published earlier this month by University at Buffalo engineers.

“Engineering blood vessels for bypass surgery, promoting the formation of new blood vessels or regenerating new skin tissue using stem cells obtained from the most accessible source — hair follicles — is a real possibility,” said Stelios T. Andreadis, Ph.D., co-author of the paper in Cardiovascular Research and associate professor in the Department of Chemical and Biological Engineering in the UB School of Engineering and Applied Sciences.

Researchers from other institutions previously had shown that hair follicles contain stem cells.

In the current paper, the UB researchers demonstrate that stem cells isolated from sheep hair follicles contain the smooth muscle cells that grow new vasculature. The group recently produced data showing that stem cells from human hair follicles also differentiate into contractile smooth muscle cells.

“We have demonstrated that engineered blood vessels prepared with smooth muscle progenitor cells from hair follicles are capable of dilating and constricting, critical properties that make them ideal for engineering cardiovascular tissue regeneration,” said Andreadis.

In addition to growing new skin for burn victims, cells from hair follicles could potentially be used to engineer vascular grafts and possibly regenerate cardiac tissues for patients with heart problems.

Since smooth muscle cells comprise the muscle of numerous tissues and organs, including the bladder, abdominal cavity and gastrointestinal and respiratory tracts, this new, accessible source of cells may make possible future treatments that allow for the regeneration of these damaged organs as well.

Andreadis and his colleagues previously engineered functional and implantable blood vessels with smooth muscle and endothelial cells originating from bone-marrow mesenchymal stem cells.

A key advantage of mesenchymal cells is that they typically do not trigger an immune reaction when transplanted, he said.

“Preliminary experiments in our laboratory suggest an exciting possibility — that stem cells from hair follicles may be similar to bone-marrow mesenchymal cells,” Andreadis said.

“The best case scenario is that from this one very accessible and highly proliferative source of stem cells, we will be able to obtain multiple different cell types that can be used for a broad range of applications in regenerative medicine,” he said.

Co-authors on the paper are Jin Yu Liu, Ph.D., research assistant professor, and Hao Fan Peng, a doctoral candidate, both in the UB Department of Chemical and Biological Engineering.

The work was funded by the John R. Oishei Foundation of Buffalo. Previous work by Andreadis has been funded by UB’s Integrative Research and Creative Activities Fund in the UB Office of the Vice President for Research.

Early Research Suggests Umbilical Cord Blood Cell Therapy May Reduce Progression of Alzheimer’s Disease

Tuesday, April 1st, 2008

OLDSMAR, Fla., March 27, 2008 /PRNewswire-FirstCall via COMTEX/ — Stems cells derived from umbilical cord blood are showing early potential in fighting Alzheimer’s disease, according to results from a new preclinical study published in the March issue of Stem Cells and Development. The study, conducted by researchers from the University of South Florida and Saneron CCEL Therapeutics, Inc., found that targeted immune suppression using stem cells derived from human umbilical cord blood reduced Alzheimer’s disease progression in a mouse model. Alzheimer’s disease is a progressive and incurable brain disease that affects more than five million people in the United States alone. The ongoing research project has been funded in part by Cryo-Cell International, Inc., an industry leader in stem cell innovation and one of the nation’s largest and most established family cord blood banks. Additional study sponsors are the National Institutes of Health’s STTR grant program, Florida High Tech Corridor Matching grant program, and the Johnnie B. Byrd, Sr. Alzheimer’s Center and Research Institute.”

An abundance of research conducted in the last two decades alone has demonstrated the life-saving potential of stem cells derived from umbilical cord blood. In fact, stem cells found in cord blood have been proven to treat more than 70 life-threatening illnesses, including leukemia, neuroblastoma, ischemic brain injury and Type 1 diabetes. Since the first successful cord blood stem cell transplant in 1988, cord blood stem cells have been used in more than 7,000 transplants. Each year, an estimated 12,000 Americans could benefit from a stem cell transplant.

“The scientific community has only skimmed the surface in uncovering the many potential therapeutic uses for cord blood stem cells, and this new research in Alzheimer’s disease may pave the way for discoveries around the use of these cells for a host of neurodegenerative and other chronic conditions,” said Mercedes Walton, Chairman and CEO, Cryo-Cell International. “Cryo-Cell is committed to supporting this important research, in addition to leading groundbreaking studies of our own to explore the potential of non- controversial stem cells. We are encouraged by studies that continue to reaffirm the benefit of cord blood, and the value of storing one’s own cord blood for future use.”

About the Study

During the study, researchers administered a series of low-dose infusions of umbilical cord blood cells into mice with abnormalities mimicking Alzheimer’s disease. As they observed the mice, they found that the levels of amyloid-beta proteins, which are key markers of Alzheimer’s progression in the brain, were reduced by nearly two-thirds (62%), and cerebral amyloid angiopathy (CAA, another marker of the disease in which the amyloid proteins harden the brain’s blood vessel walls) was improved by 86 percent. The cord blood infusions were shown to suppress the inflammatory activity, which indicates their potential to block the inflammatory response involved in Alzheimer’s disease and also related disorders.

Importantly, these reductions were associated with managing circulating and brain soluble CD40L levels, amino acids that are key contributors to brain inflammation and disease progression. Previous research has suggested that blocking CD40L levels can help minimize amyloid protein activity, improve cognition and manage disease progression in Alzheimer’s models. The study concluded that the therapy may alleviate several important pathological changes in the brain associated with Alzheimer’s disease, and should be studied further in human trials to fully understand its potential.

“We are looking closely at how stem cells can benefit particular conditions that involve degeneration of tissue, including Alzheimer’s disease,” said Cyndy Sanberg, Ph.D., Vice President, Research and Development for Saneron CCEL Therapeutics, Inc. and co-author on the study. “Research suggests that we will continue to find positive outcomes from these cell therapies in this and other related diseases that are in need of significant therapeutic options.”

Cryo-Cell offers an umbilical cord blood storage service to the public called U-Cord(R: 64.23, +3.32, +5.45%), in which cord blood stem cells are processed and cryogenically preserved in a safe and secure, state-of-the-art environment. Expectant parents receive a U-Cord Collection Kit when they are ready to give birth. Immediately after the baby is born and the umbilical cord is clamped and cut, the health professional uses a blood collection bag to draw blood from the umbilical cord. This process is painless and poses no risk to baby or mother.

Cryo-Cell tests the blood for infectious diseases and microbiological contamination to ensure that it is safe for future use. The cells are then prepared for long-term storage through a technique called controlled-rate freezing. Research has shown the cells are viable after 15 years, but stored cells are available for immediate use if needed. Every Cryo-Cell sample used for transplantation has been viable after thawing and dozens have been used in successful transplants to treat life-threatening conditions.
