Novocell Inc., a stem cell engineering company, announced research findings that for the first time identify two prominent cancer cell signaling pathways as essential for the efficient proliferation and self-renewal of human embryonic stem cells (hESCs). The findings were prepublished online August 29, 2007 in Blood First Edition Paper titled "Self-Renewal of Human Embryonic Stem Cells Requires Insulin-like Growth Factor-1 Receptor and ERBB2 Receptor Signaling.

A drug that shuts down a critical cell-signaling pathway in the most common and aggressive type of adult brain cancer successfully kills cancer stem cells thought to fuel tumor growth and help cancers evade drug and radiation therapy, a Johns Hopkins study shows. - [Read more]

Researchers at the National Institutes of Health (NIH) have discovered a novel cause of iron overload in patients with thalassemia, a genetic blood disorder that causes anemia. - [Read more]

Some scientific results are hard to spot, especially in genetic research. Often scientists are unable to physically see if the gene they inserted into a cell has produced the desired trait. To overcome this problem researchers use various genetic markers that contain pieces of foreign DNA that cause cells to, for example, glow when exposed to ultraviolet light.

In the September 15th issue of Genes & Development, Drs. Richard T. Williams, Willem den Besten, and Charles J. Sherr at Howard Hughes Medical Institute, St. Jude Childrens Research Hospital in Memphis TN, lend new insights into how an aggressive form of acute lymphoblastic leukemia (ALL) develops, and how sensitivity to the targeted chemotherapeutic drug, imatinib, can be diminished through interactions between tumor cells and the host microenvironment. - [Read more]

A cannibalistic process called autophagy spurs dying embryonic stem cells to send "eat me" and "come get me" signals to have their corpses purged, a last gasp that paves the way for normal mammalian development, UT Southwestern Medical Center researchers have found. - [Read more]

How do adult stem cells protect themselves from accumulating genetic mutations that can lead to cancer? - [Read more]

Results of a study by investigators at St. Jude Childrens Research Hospital provide strong evidence for why the drug imatinib (Gleevec), which has revolutionized the treatment of chronic myelogenous leukemia (CML), is often unable to prevent relapse of a particularly aggressive form of acute lymphoblastic leukemia (ALL). - [Read more]

Researchers from 22 countries migrated to Cleveland for a bench to bedside examination of the developing mesenchymal stem cells (MSC) from regenerative medicine and stem cell research to therapeutics in patient care. [click link for full article] - [Read more]

When human heart muscle cells derived from embryonic stem cells are implanted into a rat after a heart attack, they can help rebuild the animals heart muscle and improve function of the organ, scientists report in the September issue of Nature Biotechnology. The researchers also developed a new process that greatly improves how stem cells are turned into heart muscle cells and then survive after being implanted in the damaged rat heart.

Working with embryonic mouse brains, a team of Johns Hopkins scientists seems to have discovered an almost-too-easy way to distinguish between "true" neural stem cells and similar, but less potent versions. Their finding, reported this week in Nature, could simplify the isolation of stem cells not only from brain but also other body tissues. [click link for full article] - [Read more]

The group Cures Without Cloning on Wednesday filed a ballot proposal with the Missouri Secretary of State seeking to modify a state constitutional amendment that protects human embryonic stem cell research, the [click link for full article] - [Read more]

Geron Corporation has reported its scientists and collaborators have demonstrated that human embryonic stem cell (hESC)-derived cardiomyocytes improve heart function when transplanted after myocardial infarction. - [Read more]

A mosquito-borne disease often known as "break-bone fever" has found a new enemy in a unique type of mouse. - [Read more]

World renowned experts on motor neurone disease will share their work at an international symposium hosted by the University of Edinburgh tomorrow (WED) to enable greater understanding of the condition. - [Read more]

Not only can human embryonic stem cells restore damaged hearts, they can also improve heart function and significantly hold back the progression of heart failure, say scientists from the Center for Cardiovascular Biology and Regenerative Medicine at the University of Washington, in Seattle, who carried out experiments on rats. You can read about this in the journal Nature Biotechnology. [click link for full article] - [Read more]

Researchers at BRIC, University of Copenhagen, have identified a new gene family (UTX-JMJD3) essential for embryonic development. The family controls the expression of genes crucial for stem cell maintenance and differentiation, and the results may contribute significantly to the understanding of the development of cancer.

All organisms consist of a number of different cell types each producing different proteins. The nerve cells produce proteins necessary for the nerve cell function; the muscle cells proteins necessary for the muscle function and so on. All these specialised cells originate from the same cell type the embryonic stem cells. In a highly controlled process called differentiation, the stem cells are induced to become specialised cells.

In an upcoming issue of G&D, Drs. Maria Divina Deato and Robert Tjian (HHMI, UC Berkeley) reveal that the formation of an alternative transcriptional core promoter complex directs cell-type specific differentiation during myogenesis. The article uncovers a whole new level of transcriptional control of terminal cell differentiation, and will be published online ahead of its September 1 print date at http://www.genesdev.org/.
