Salamander research findings bring scientists closer to future regenerative therapies

Tissue regeneration in salamanders and newts seems like it should be the stuff of science fiction. But it happens routinely. Why can't we mammals just re-grow a limb or churn out a few new heart muscle cells as needed? New research suggests there might be a very good reason: Restricting our cells' ability to pop in and out of the cell cycle at will - a prerequisite for the cell division necessary to make new tissue - reduces the chances that they'll run amok and form potentially deadly cancers.

Researchers reprogram human embryonic stem cells to iPS cells for use in regenerative medicine

Human embryonic stem (ES) cells and adult cells reprogrammed to an embryonic stem cell-like state-so-called induced pluripotent stem or iPS cells-exhibit very few differences in their gene expression signatures and are nearly indistinguishable in their chromatin state, according to Whitehead Institute researchers.The pluripotency of ES cells fueled excitement over their use in regenerative medicine. While ethical hurdles associated with the clinical application of human ES cells appeared to have been overcome with the development of methods to create iPS cells, some recent research has suggested that ES and iPS cells have substantial differences in which sets of genes they express.

Scientists find new way to make beating heart cells from body's own cells

Scientists at the Gladstone Institute of Cardiovascular Disease have found a new way to make beating heart cells from the body's own cells that could help regenerate damaged hearts. Over 5 million Americans suffer from heart failure because the heart has virtually no ability to repair itself after a heart attack.

Scientists find molecular cocktail to transform non-muscle cells into cardiac muscle

In heart disease, cardiac muscle gradually dies off and, with little or no way to regenerate those cells, that can ultimately lead the heart to fail. But scientists reporting in the August 6th issue of Cell, a Cell Press publication, might have found a way to fix those losses. They've devised a three-ingredient molecular cocktail that transforms fibroblasts - structural cells that the heart is chock full of - directly into beating heart cells.

Axiogenesis signs non-exclusive license agreement with iPS Academia

Axiogenesis AG and iPS Academia Japan Inc. (Kyoto, Japan) announced that they have executed a non-exclusive agreement with iPS Academia (Kyoto, Japan) through which Axiogenesis obtains worldwide access to the extensive portfolio of induced pluripotent stem cell technology for iPSC-derived cardiomyocytes and other cell types, pioneered by Professor Shinya Yamanaka, Center for iPS Cell Research and Application at the University of Kyoto, Japan.

FDA lifts hold, allows Geron to proceed with Phase I clinical trial of GRNOPC1 in spinal cord injury

Geron Corporation announced today that the U.S. Food and Drug Administration (FDA) has notified the company that the clinical hold placed on Geron's Investigational New Drug (IND) application has been lifted and the company's Phase I clinical trial of GRNOPC1 in patients with acute spinal cord injury may proceed.

Human fat tissue can be reprogrammed to yield clinically useful stem cells: Research

Australian scientists from the Monash Institute of Medical Research have "reprogrammed" adult mouse fat cells and neural cells to become stem cells that can differentiate into a variety of different cells (pluripotency). The cells, called "induced pluripotent stem cells" are nearly identical to the naturally occurring pluripotent stems cells, such as embryonic stem cells, which are highly pluripotent, in short supply and their access restricted in the U.S.

Glioblastomas patients with affected stem cell niche experience progression-free survival

Patients with deadly glioblastomas who received high doses of radiation that hit a portion of the brain that harbors neural stem cells had double the progression-free survival time as patients who had lower doses or no radiation targeting the area, a study from the Radiation Oncology Department at UCLA's Jonsson Comprehensive Cancer Center has found.

Researchers reveal findings on restricted lineage of iPS cells

Adult cells that have been reprogrammed into induced pluripotent stem cells (iPS cells) do not completely let go of their past, perhaps limiting their ability to function as a less controversial alternative to embryonic stem cells for basic research and cell replacement therapies, according to researchers at Children's Hospital Boston, John Hopkins University and their colleagues

Tet 1 protein helps stem cells renew themselves and stay pluripotent: Researchers

Take a skin cell from a patient with Type 1 diabetes. Strip out everything that made it a skin cell, then reprogram it to grow into a colony of pancreatic beta cells. Implant these into your patient and voilà! She's producing her own insulin like a pro.

Researchers develop new strategy for treating multiple myeloma

Multiple myeloma is one of the most common blood cancers, and at present considered to be incurable. In a new study from Uppsala University, researchers now present a conceptually new model for the development and progression of multiple myeloma. The study was done in collaboration with Vrije Universitet Brussels and is published in the July edition of the on-line journal PLoS ONE.

New approach in treating heart attack, cardiomyopathy using stem cells

Presenting at the UK National Stem Cell Network annual science conference today (13 July), Professor Michael Schneider describes a new approach to treating heart attack and cardiomyopathy using stem cells.

Experts use Mexican aquatic salamander to study evolution and genetics of stem cells

Dr Andrew Johnson is speaking today (12 July) at the UK National Stem Cell Network annual conference. He and his team from the University of Nottingham have been using a Mexican aquatic salamander called an axolotl to study the evolution and genetics of stem cells - research that supports the development of regenerative medicine to treat the consequences of disease and injury using stem cell therapies. This team has found that there are extraordinary similarities in the development of axolotls and mammals that provide unique opportunities to study the properties of embryonic stem cells and germ cells.

Biologists discover new way to limit formation of teratomas

One of the characteristics of embryonic stem cells is their ability to form unusual tumors called teratomas. These tumors, which contain a mixture of cells from a variety of tissues and organs of the body, are typically benign. But they present a major obstacle to the development of human embryonic stem cell therapies that seek to treat a variety of human ailments such as Parkinson's, diabetes, genetic blood disorders and spinal cord injuries.

Amniocentesis and non-embryonic stem cells among list of "Huge Medical Breakthroughs"

Two key focus areas of Biocell Center, the nation's first amniotic fluid stem cell bank, have been recently mentioned among the most important medical discoveries of the last century. Amniocentesis and non-embryonic stem cells were among the list of "Huge Medical Breakthroughs" presented in an article by Althea Chang on Mainstreet.com, produced by TheStreet.com on June 29, 2010.

Ronin, Hcf-1 bind together to control gene program that stimulates growth of stem cells

Ronin, crucial to the self-renewal of embryonic stem cells, and a co-regulator called Hcf-1, binds to a small strand of DNA called a hyperconserved enhancer element to control a gene "program" that stimulates growth of the stem cells and may even play a role in cancer, said a group of researchers led by Baylor College of Medicine in a current report in the journal Genes and Development.

Tel Aviv University develops method for tracking progression of adult stem cells

It's a new technology that uses molecular therapy to coax adult cells to revert to an embryonic stem cell-like state, allowing scientists to later re-differentiate these cells into specific types with the potential to treat heart attacks or diseases such as Parkinson's.
