Stem Cells News and Research

RSS

Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive. When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.

Discovery may have implications for the treatment of hemophilia A and B

University of North Carolina at Chapel Hill researchers have made a discovery that may have implications for the treatment of liver-based genetic defects such as hemophilia A and B in humans.

Mesoblast signs adult stem cells agreement

Australia’s adult stem cell company, Mesoblast Limited, today announced that it had signed an agreement for production of specialised adult stem cells, known as Mesenchymal Precursor Cells (MPCs), to be used in human pilot clinical trials in patients with orthopaedic and cardiovascular diseases.

First evidence of cardiac progenitor cells

The first evidence of cardiac progenitor cells – rare, specialized stem cells located in the newborn heart of rats, mice and humans – has been shown by researchers at the University of California, San Diego (UCSD) School of Medicine. The cells are capable of differentiation into fully mature heart tissue.

Researchers have discovered an ample source of stem cells in an uncharted part of the umbilical cord

The study, published in the February issue of Stem Cells, outlines how researchers discovered that the jelly-like connective tissue surrounding the blood vessels of the human umbilical cord, the so-called "Wharton's Jelly," is rich in mesenchymal progenitor cells – cells that generate bone, cartilage and other tissues – and can be harvested to generate an abundant supply in a short amount of time.

Inserting corrective genes into the brain to fight Parkinson's disease

An international team of scientists has used gene therapy in two separate studies to renew brain cells and restore normal movements in monkeys and rats with a drug-induced form of Parkinson's disease.

Level of immune cell DNA in the blood might help predict success of stem cell transplantation

Measuring the quantity of a certain type of immune cell DNA in the blood could help physicians predict whether a bone marrow stem cell transplant will successfully restore a population of infection-fighting cells called T lymphocytes in a child.

Origins of skin cancer melanoma

Researchers at Children's Hospital Boston and the Dana-Farber Cancer Institute have found an important clue about the origins of the deadly skin cancer melanoma.

Significant advance toward understanding lifelong process of blood cell formation

A research study published in the February issue of Developmental Cell expands on previous studies by using adult animals to examine the role of a key gene known to be required for blood cell formation. Information gained from this research will be useful for future studies aimed at directing stem cell differentiation in a variety of potential therapeutic contexts.

Scientists have coaxed human embryonic stem cells to become spinal motor neurons

After years of trial and error, scientists have coaxed human embryonic stem cells to become spinal motor neurons, critical nervous system pathways that relay messages from the brain to the rest of the body.

Startling results from new biomedical research will smooth path to the market place

Researchers have discovered how to convert liver cells of mice into pancreatic cells using a single injection. This may eventually lead to a cure for diabetes. Dr. James Mittra, one of the organisers of an international conference in Edinburgh on the Evolution of the Life Science Industries asks, “How does the pharmaceutical industry respond to this kind of work? They are primarily interested in treatments, not cures. Do they see this kind of research as a threat?”

Stem cells given in minimally invasive procedure improve heart function

Patients with severe congestive heart failure who had exhausted all other treatment options showed markedly improved heart function following a procedure in which their own stem cells were deployed directly into the heart by way of four tiny incisions in the chest, according to results of a trial presented today at the 41st Annual Meeting of the Society for Thoracic Surgery.

Local environment directly influences adult stem cell reservoirs

Using the common fruit fly, researchers at UT Southwestern Medical Center have discovered that an intricate set of signals released by stem cells' surroundings governs their maintenance.

Aastrom Biosciences responds to article regarding contaminated stem cell lines

Aastrom Biosciences responded today to the publication in the Sunday online edition of Nature Medicine of findings by California researchers that indicate that certain lines of human embryonic stem cells have been contaminated through the use of mice feeder cells.

Available lines of human embryonic stem cells have been contaminated

Currently available lines of human embryonic stem cells have been contaminated with a non-human molecule that compromises their potential therapeutic use in human subjects, according to research by investigators at the University of California, San Diego (UCSD) School of Medicine and the Salk Institute in La Jolla, California.

Priming embryonic stem cells to fulfill their promise

Bioengineering researchers at the University of California, San Diego have invented a process to help turn embryonic stem cells into the types of specialized cells being sought as possible treatments for dozens of human diseases and health conditions.

Clinical trial planned for stem cell treatment for stress urinary incontinence

ITL Laboratories, L.L.C. ("ITL") is planning a clinical trial to determine the effectiveness of a stem cell treatment for stress urinary incontinence. A recent clinical trial by Austrian researchers has demonstrated the potential usefulness of expanded muscle stem cell injections in the treatment of urinary incontinence.

Cord blood transplantation now a viable option for adult leukemia patients

Stem cell transplantation using umbilical cord blood is a standard treatment option for blood disorders in children, but not for adults, due to the difficulty of obtaining a sufficiently large dose of cells.

Elsevier to launch journal devoted to nanomedicine

Elsevier has announced plans to launch a peer-reviewed journal devoted to nanomedicine - the emerging science of using molecular machines to treat human disease. Nanomedicine: Nanotechnology, Biology, and Medicine, the official publication of the American Academy of Nanomedicine, will be published quarterly, with the first issue to appear in March 2005.

Lowering health care costs overall seen as top U.S. health priority

The public favors reducing jury awards in malpractice lawsuits and allowing drugs to be imported from Canada, but ranks them relatively low on a list of 12 health care priorities for President Bush and Congress to address this year, according to a new post-election survey conducted by the Kaiser Family Foundation and the Harvard School of Public Health.
