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.

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.

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.

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.

Recent study correlates human cord blood cells with reduced animal heart attack damage

Researchers from the University of South Florida (USF) and James A. Haley Veterans Hospital have reported in the journal "Cell Transplantation" that stem cells from umbilical cord blood effectively treated heart attacks in an animal study.

Stem cells from umbilical cord blood effectively treated heart attacks

When injected into rats' hearts soon after a heart attack, stem cells taken from human umbilical cord blood (HUCB) greatly reduced the size of heart damage and restored pumping function to near normal. This improvement occurred without the need for drugs to prevent the rats' immune system from rejecting the human cells.

Discovery shows how embryonic stem cells perform 'quality control' inspections

Biologists at the University of California, San Diego have found a fundamental mechanism used by embryonic stem cells to assure that genetically damaged stem cells do not divide and pass along the damage to daughter stem cells.

Cell replacement therapy offers a novel and powerful medical technology

Cell replacement therapy offers a novel and powerful medical technology. A type of embryonic stem cell, called a neural crest stem cell, that persists into adulthood in hair follicles was recently discovered by Maya Sieber-Blum, Ph.D., of the Medical College of Wisconsin, Milos Grim, MD Ph.D., of Charles University Prague, and their collaborators.

New advances in sickle cell disease

Excruciating pain episodes, recurrent pneumonias, strokes, severe infections, chronic hemolytic anemia, and secondary pulmonary hypertension are common complications of sickle cell disease, a life-threatening inherited defect in blood that causes normally disc-shaped red blood cells to take on a sickle shape.

Scientist develops way to deliver promising genetic tool into living cells

By exploiting an HIV protein that readily traverses cell membranes, Carnegie Mellon University scientists have developed a new way to introduce a gene-like molecule called a peptide nucleic acid (PNA) directly into live mammalian cells, including human embryonic stem (ES) cells.

Genetic mutations and cellular modifications may provide clues to the associations between slight genetic abnormalities and often fatal diseases

Modern research is delving deep into the human genome to find the answers to medical mysteries and, hopefully, cures for the most deadly diseases. According to four new studies presented during the 46th Annual Meeting of the American Society of Hematology

5 Dec 2004

New research may lead to new treatments for spinal cord injury and multiple sclerosis

For the first time, researchers have used human embryonic stem cells to create new insulating tissue for nerve fibers in a live animal model – a finding that has potentially important implications for treatment of spinal cord injury and multiple sclerosis.

23 Nov 2004

Scientists have developed a fast and safe method for collecting heart stem cells from small amounts of biopsied heart tissue

In human and animal studies, scientists at Johns Hopkins have developed a fast and safe method for collecting heart stem cells from remarkably small amounts of biopsied heart tissue (15 mg or less), and growing the cells in the lab to get more.

Expert panel see hope for stem cell use as diabetes cure

A report from a medical panel of academic and community-based endocrinologists and transplant surgeons acknowledged that a recent study supports the use of stem cells as a future cure for type I diabetes.

1 Nov 2004

Researchers are one step closer to understanding how blood cells develop through the use of human embryonic stem cells

This process is also significant because the blood cells were developed without the use of animal serum, which was previously thought to be essential for blood cell development. Instead, specific growth factors are added to guide the cell differentiation.

Discovery affirms potential of stem cells for the development of possible therapies for spinal cord injury and nervous system disorders

Researchers at The Hospital for Sick Children (Sick Kids) have shown that stem cells found in adult skin retain their embryonic capability of making many types of cells.

1 Nov 2004

As the 2004 Presidential election nears, the issue of human cloning and embryonic stem cell research is under intense debate

The United Nations, headed by Secretary General Kofi Annan is currently debating two proposals: one from Costa Rica and supported by the U.S. and sixty-two other countries that would ban all human cloning, and another from Belgium and twenty-one other countries that would allow cloning of human embryos but not their transfer to a womb.

25 Oct 2004

Researchers suggest how to generate B cells from stem cells

Before stem cells, of whatever origin, can be used to treat patients, scientists will need to learn how to coax them to develop into the desired cell types, a major challenge.
