Artificial testes being developed to help infertile men produce sperm

Californian researchers are trying to create an artificial testicle that will produce human sperm. Dr. Paul Turek, director of the Turek Clinic in San Francisco, which specializes in male infertility, said the goal is not to create a testicular implant for men, but a “sperm-making biological machine” that will help scientists learn more about just what causes male infertility. “We’re trying to recreate the process of sperm production in a three-dimensional system,” Turek said. “Simple laboratory conditions can’t get it done in humans. Our concept is to actually recreate the testicle itself.”

MSC-mediated RNAi transfer holds promise for Huntington's disease

A team of researchers at the UC Davis Institute for Regenerative Cures has developed a technique for using stem cells to deliver therapy that specifically targets the genetic abnormality found in Huntington's disease, a hereditary brain disorder that causes progressive uncontrolled movements, dementia and death.

Converted umbilical cord stem cells hold hope for spinal cord injuries, multiple sclerosis

For the first time ever, stem cells from umbilical cords have been converted into other types of cells, which may eventually lead to new treatment options for spinal cord injuries and multiple sclerosis, among other nervous system diseases.

Researchers produce chimeric monkeys with six distinct genomes

Researchers have produced the world's first chimeric monkeys. The bodies of these monkeys, which are normal and healthy, are composed of a mixture of cells representing as many as six distinct genomes.

New information about how early ESCs develop and form primate species

Newly published research by scientists at Oregon Health & Science University provides significant new information about how early embryonic stem cells develop and take part in formation of the primate species.

BioTime to market muscle progenitor cell lines bearing hereditary diseases

BioTime, Inc. today announced that it has elected to market progenitors of muscle stem cells bearing hereditary diseases. BioTime will produce the products from five human embryonic stem (hES) cell lines from Reproductive Genetics Institute (RGI) of Chicago, Illinois.

Roundup: HIV staff to be cut in Ga.; Abortion news in N.J., Mo.; Wis. Medicaid coverage in limbo

A loss of $3.7 million in federal funds is forcing Georgia to reduce its workforce for HIV prevention. After an inquiry by Georgia Health News, the Department of Public Health this week acknowledged that 20 people in state health districts have been notified they will probably lose their jobs in January, and that an unspecified number of staffers at the department level have received the same notification.

Researchers identify molecules that can stimulate heart muscle regeneration

Damaged heart tissue is not known for having much inherent capacity for repair. But now, scientists are closing in on signals that may be able to coax the heart into producing replacement cardiac muscle cells. Using a zebrafish model system, researchers have identified a family of molecules that can stimulate stem cells to develop into beating heart muscle cells.

Gladstone Senior Investigator named AAAS fellow for cardiac and stem cell research

The American Association for the Advancement of Science (AAAS) has named Gladstone Senior Investigator Deepak Srivastava, MD, a Fellow for his efforts to advance science and its applications.

Researchers convert astrocytes directly into dopamine-producing neurons

In efforts to find new treatments for Parkinson's Disease (PD), researchers from the Perelman School of Medicine at the University of Pennsylvania have directly reprogrammed astrocytes, the most plentiful cell type in the central nervous system, into dopamine-producing neurons.

Research examines novel treatment techniques for hemophilia B, VTE

Bleeding and clotting disorders affect a large number of patients annually and, while accurate diagnosis is important, timely and effective treatment for these disorders is key, as they have the potential to quickly become life-threatening. Research examining novel treatment techniques for bleeding and clotting disorders will be presented today at the 53rd Annual Meeting of the American Society of Hematology.

Researchers discover molecular marker for immediate precursors of blood stem cells

A research team led by Nancy Speck, PhD, professor of Cell and Developmental Biology at the Perelman School of Medicine at the University of Pennsylvania, has discovered a molecular marker for the immediate precursors of hematopoietic (blood) stem cells (HSCs) in the developing embryo, which provides much-needed insights for making these cells from engineered precursors.

“Gold standard” stem cells for clinical testing

British researchers claim to have created stem cells of a “gold standard” quality that could lead to a new wave of treatments for degenerative diseases. Taken from human embryos, they could be available to researchers before the end of next year for eventual use in clinical trials, The Daily Telegraph reported Tuesday.

King's College London submits first clinical grade xeno-free hES cell lines to the UKSCB

Stem cell scientists at King's College London will announce they have submitted to the UK Stem Cell Bank (UKSCB) their first clinical grade human embryonic stem (hES) cell lines that are free from animal-derived products, known as 'xeno-free' stem cells.

Stem cells for the damaged heart

Stem cell research got its latest boost. For the first time, stem cells were injected into the hearts of humans who had suffered serious heart damage, and patients improved dramatically. The scientists found that the stem cells grew into new heart cells to replace the damaged tissue.

Established human embryonic cell lines vary from newly derived stem cell lines

Established human embryonic cell lines, including those approved for federal research funding under former President George W. Bush, are different than newly derived human embryonic stem cell lines, according to a study by UCLA stem cell researchers.

New discovery of adult stem cells gives fresh possibilities for heart regeneration

Sydney researchers have discovered a new population of adult stem cells in the heart, which could augment the development of new regeneration and repair therapies for people who have suffered heart attack or heart failure, the leading cause of death in Australia.
