Clues about how blood forms could yield new strategies for treating blood diseases

Biologists have long wondered why the embryonic heart begins beating so early, before the tissues actually need to be infused with blood.

Molecule Thymosin beta-4 prompts damaged heart cells to repair themselves after a heart attack

A protein that the heart produces during its early development reactivates the embryonic coronary developmental program and initiates migration of heart cells and blood vessel growth after a heart attack, researchers at UT Southwestern Medical Center have found.

Creating ideal neural cells for clinical use

Investigators at the Burnham Institute for Medical Research (Burnham) have developed a protocol to rapidly differentiate human embryonic stem cells (hESCs) into neural progenitor cells that may be ideal for transplantation.

Researchers develop mouse models of leukemia that predict response to chemotherapy

Being able to accurately predict how a given cancer will respond to chemotherapy would spare patients with non-responsive tumors the burden of undergoing toxic and ultimately unhelpful treatment.

Amniotic fluid may be a new source of stem cells

For the first time, scientists have shown that amniotic fluid (the protective liquid surrounding an embryo) may be a potential new source of stem cells for therapeutic applications. The study was prepublished online on February 12, 2009, in Blood, the official journal of the American Society of Hematology.

Eye cells believed to be retinal stem cells are misidentified

Cells isolated from the eye that many scientists believed were retinal stem cells are, in fact, normal adult cells, investigators at St. Jude Children's Research Hospital have found.

How your brain grows might come down to how your cells divide

In the April 6 issue of the Journal of Cell Biology (JCB), Lake and Sokol report that mouse protein Vangl2 controls the asymmetrical cell division and developmental fate of progenitor neurons.

Post heart attack, bone marrow stem cells increase blood flow within heart

Patients treated with their own bone marrow stem cells after a heart attack experienced increased circulation within the heart, a study by Emory University School of Medicine physicians has found.

ArunA Biomedical to commercialize human embryonic stem cell derived mesenchymal cells

ArunA Biomedical, Inc., has announced that it will make its CELL-EZ brand hMC human mesenchymal progenitor cells commercially available to the research community in mid 2009.

Data suggesting that omacetaxine can eradicate leukemic stem cells may offer a breakthrough for CML

Data showing the ability of omacetaxine to kill leukemic stem cells in mouse models with drug-resistant chronic myelogenous leukemia (CML) are the subject of an advance online publication in the journal Leukemia, ChemGenex Pharmaceuticals Limited (ASX:CXS and NASDAQ:CXSP) announced today.

Human adult testes cells can become embryonic-like

Using what they say is a relatively simple method, scientists at Georgetown University Medical Center have extracted stem/progenitor cells from testes and have converted them back into pluripotent embryonic-like stem cells.

Schizophrenia gene found to control the birth of new neurons

A gene that is arguably the most studied "schizophrenia gene" plays an unanticipated role in the brain: It controls the birth of new neurons in addition to their integration into existing brain circuitry, according to a report in the March 20th issue of the journal Cell, a Cell Press publication.

Stem cell infusion and hyperbaric oxygen treatment improve islet function in diabetes

A study to determine if patients with type 2 diabetes can benefit from a combination of autologous (patient self-donated) stem cell infusions (ASC) and hyperbaric (above the normal air pressure of ) oxygen treatment (HBO) before and after ASC has found "significant benefits" in terms of "improvements in glycemic control" along with "reduced insulin requirements."

Advances in stem cell research

Scientists at The University of Texas Health Science Center at Houston are on the forefront of stem cell research, developing novel therapies designed to generate heart cells, repair traumatic lung injuries, grow new bone and stanch the spread of cancer cells.
