New system for growing human embryonic stem cells could make therapies utilising the cells safer for patients

A new system for growing human embryonic stem cells could make therapies utilising the cells safer for patients, concludes a study published online by The Lancet (Tuesday, March 8, 2005).

System for producing embryonic stem cells which markedly reduces the risk of contamination with pathogens

A.C.T. Holdings and Advanced Cell Technology, Inc. (ACT) reported the first derivation of human embryonic stem cells in completely feeder-layer-free and serum-free conditions.

UK will vote against the declaration on human cloning

The UN declaration is non-binding and has no legal status, but it calls on countries to prohibit all forms of human cloning. This is totally unacceptable to the UK government which strongly supports stem cell research, including embryonic stem cell research which involves the use of cloning technology.

Cells can regenerate without becoming "younger"

It has long been thought that cells that regenerate tissue do so by regressing to a developmentally younger state. Now two University of Washington researchers have demonstrated that cells can regenerate without becoming "younger."

Early Alzheimer's disease may be precipitated by a neuron traffic jam

Early Alzheimer's disease may be precipitated by a “traffic jam” within neurons that causes swelling and prevents proper transport of proteins and structures in the cells, according to new studies by Howard Hughes Medical Institute researchers.

Massachusetts support of stem cell research

The Massachusetts Medical Society, the statewide association of physicians with some 18,000 members, has offered testimony before the Joint Committee on Economic Development and Emerging Technologies in support of Senate Bill 25, An Act Promoting Stem Cell Research.

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

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.
