Researchers return blood cells to stem cell state
Johns Hopkins scientists have developed a reliable method to turn the clock back on blood cells, restoring them to a primitive stem cell state from which they can then develop into any other type of cell in the body.

Scientists make insulin-producing cells self-replicate
(Medical Xpress)—Scientists have discovered a hormone that causes the body's insulin-producing factories, beta cells, to churn out more of themselves. Having enough insulin is critical to regulating the amount of sugar ...

Pluripotency
Pluripotency in the broad sense refers to "having more than one potential outcome." In biological systems, this can refer either to cells or to biological compounds. From the Latin pluri=many, potent=power, capacity. A pluripotent cell can create all cell types except for extra embryonic tissue, unlike a totipotent cell, (tot=all), which can produce every cell type including extra embryonic tissue.
