The source of stem cells points to two proteins
While other animal embryos grow outside the mother, their embryonic cells can get right to work accepting assignments, such as head, tail or vital organ. By contrast, mammalian embryos must first choose between forming the placenta or creating the baby. New research has pinpointed two proteins that are the keys to this decision making. The process of assigning cells to placenta or baby is important because that is when pluripotent cells are made. These adaptable pluripotent cells are critical to stem cell research.

Potential seen for tailoring treatment for acute myeloid leukemia
Rapid screening of leukemia cells for drug susceptibility and resistance are bringing scientists closer to patient-tailored treatment for acute myeloid leukemia. Research on the differing drug response patterns of leukemia stem cells and blasts may show why some attempts to treat are not successful and why some patients relapse.

Sea invertebrate sheds light on evolution of human blood, immune systems
Botryllus schlosseri, a marine invertebrate that lives in underwater colonies resembling fuzzy pinheads clinging to rocks, has a blood-forming system with uncanny similarities to that of humans, according to scientists.

New research on stem cell transplantation for myeloid cancers
Improving outcomes for patients with myeloid cancers who undergo stem cell transplantation is a focus of several studies being presented this week.

Some blood cells have a surprising source: Your gut
The human intestine may provide up to 10 percent of blood cells in circulation from its own reservoir of blood-forming stem cells, a surprising new study has found.
