Biologists discover how yeast cells reverse aging
Human cells have a finite lifespan: They can only divide a certain number of times before they die. However, that lifespan is reset when reproductive cells are formed, which is why the children of a 20-year-old ...

McMaster researchers say not all stem cells the same
Until now it's been thought that human stem cell lines are all identical and possess the same ability to differentiate, or change into more specific cell types. But new research from McMaster University has shown there are ...

New discovery may eliminate potentially lethal side effect of stem cell therapy
Like fine chefs, scientists are seemingly approaching a day when they will be able to make nearly any type of tissue from human embryonic stem cells. You need nerves or pancreas, bone or skin? With the right combination of ...

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.
