| MED | Technique Enables Efficient Gene Targeting in Human Embryonic Stem Cells
A novel technique allows researchers to efficiently modify or introduce genes into the genomes of human embryonic stem cells (ESCs) and induced pluripotent stem (iPS) cells, according to Whitehead scientists. For years, scientists have easily swapped genes in and out of mouse ESC or iPS cell genomes, but have had a notoriously difficult time disrupting or inserting genes into their human equivalents.

| SCI | Scientists Make Multiple Types of White Blood Cells Directly from Embryonic and Adult Stem Cells
In an advance that could help transform embryonic stem cells into a multipurpose medical tool, scientists at the University of Wisconsin-Madison have transformed these versatile cells into progenitors of white blood cells and into six types of mature white blood and immune cells.

| MED | Researchers Make Stem Cells from Developing Sperm
The promise of stem cell therapy may lie in uncovering how adult cells revert back into a primordial, stem cell state, whose fate is yet to be determined. Now, cell scientists at the Johns Hopkins University School of Medicine have identified key molecular players responsible for this reversion in fruit fly sperm cells. Reporting online this week in Cell Stem Cell, researchers show that two proteins are responsible redirecting cells on the way to becoming sperm back to stem cells.

| MED | Bone from Blood: Circulating Cells Form Bone Outside the Normal Skeleton
The accepted dogma has been that bone-forming cells, derived from the body’s connective tissue, are the only cells able to form the skeleton. However, new research shows that specialized cells in the blood share a common origin with white blood cells derived from the bone marrow and that these bloodstream cells are capable of forming bone at sites distant from the original skeleton. This work represents the first example of how circulating cells may contribute to abnormal bone formation.

| SCI | Students Embed Stem Cells in Sutures to Enhance Healing
Biomedical engineering students have demonstrated a practical way to embed a patient’s stem cells in the surgical thread used to repair serious orthopedic injuries. The goal is to enhance healing and reduce the likelihood of re-injury. | 20-Jul-2009

| MED | Induced Pluripotent Stem Cells Repair Heart
In a proof-of-concept study, Mayo Clinic investigators have demonstrated that induced pluripotent stem (iPS) cells can be used to treat heart disease. iPS cells are stem cells converted from adult cells. In this study, the researchers reprogrammed ordinary fibroblasts, cells that contribute to scars such as those resulting from a heart attack, converting them into stem cells that fix heart damage caused by infarction. The findings appear in the current online issue of the journal Circulation. (Embargo expired on 20-Jul-2009 at 16:00 ET.)

In a new study that could transform embryonic stem cell (ES cell) research, scientists at UT Southwestern Medical Center have discovered why mouse ES cells can be easily grown in a laboratory while other mammalian ES cells are difficult, if not impossible, to maintain.
