New process efficiently reprograms stem cells in one step using measles virus vector

Induced pluripotent stem cells, the workhorse of many regenerative medicine projects, start out as differentiated cells that are reprogrammed to pluripotent stem cells by exposure to a complex set of genetic cocktails.

New bioengineered device enhances the production of T-cells

Bone marrow transplants, also known as hematopoietic stem cell transplants, are life-saving treatments for aggressive diseases, such as leukemia and multiple myeloma, and infections such as HIV. The procedure entails infusion of blood stem cells from a matched donor into the patient to 'reset' the blood and immune system.

Novel protein sensor allows researchers to observe nicotine's movements in cells

When a person takes a puff on a cigarette, nicotine floods into the brain, latching onto receptors on the surface of neurons and producing feelings of happiness. But nicotine does not simply stay on the surface of cells--the drug actually permeates into neural cells and alters them from the inside out.
