Exposing rats to acute stress increased the generation of new neurons in a subregion of the hippocampus, and improved the animals' performance in a memory task two weeks later.

Chronic and excessive inflammation can lead to exhaustion of the supply of hematopoietic stem cells and to myeloid malignancies in mice, mimicking important aspects of the myelodysplastic syndrome found in humans.

Lysine-specific demethylase 1 (Lsd1) has an essential role during both the early and later stages of blood cell development.

The Botryllus schlosseri genome yields insights into the evolution of hematopoiesis.

Reduced expression of MYBL2 contributes to malignancies of the blood by permitting uncontrolled expansion of blood cell progenitors, implying a tumor suppressor function for this gene.

Skin cells from a patient with retinitis pigmentosa have been used to generate induced pluripotent stem cells, which could potentially form the basis of new treatments for this disease.

While intact mir-17-92 acts as a potent oncogene in a mouse model of Burkitt’s lymphoma, one of the six mir-17-92 components antagonizes its oncogenic cooperation with c-Myc by promoting c-Myc-induced apoptosis.

Cells from the human pancreatic duct can be grown in culture and triggered to become insulin-producing cells, which could potentially be transplanted into patients with diabetes.
