UCLA researchers develop T-cells from human embryonic stem cells

...mbryonic stem cells, which were incubated on mouse bone marrow support cells, which in turn converted them into blood forming cells. Those cells were then injected into a human thymus gland that had been implanted in a mouse, and the thymus then changed those blood-forming cells into T-cells. Located just...

Fertility hope as study shows eggs survive in older ovaries

...sted that the new eggs come from stem cells in the bone marrow or the ovary, we really don't know and further experimentation is needed to find out." Dr Kerr said the phenomenon of egg regeneration in mice did not necessarily mean the same happened in humans. "But the mechanism could provide direction fo...

...hysician." Just as an orthopedist can set a broken bone but the body must do the healing, he can set up conditions that are right for oyster reefs to prosper, but factors beyond his control ?water quality, larval abundances, and other conditions he's exploring ?play a major role in his success. At five d...

Immune system police learn early and sometimes badly

...Dr. Pacholczyk says. All T cells are made in the bone marrow then move to the thymus as progenitor cells where they differentiate, upregulating surface receptors, which are molecules that detect different antigens. It's a brutal process ?95 percent of the cells die in the thymus primarily because they ...
