Adult Stem Cell Therapies
The therapeutic potential of adult stem cells is the focus of much scientific research, due to their ability to be harvested from the patient. In common with embryonic stem cells, adult stem cells have the ability to differentiate into more than one cell type, but unlike the former they are often restricted to certain types or "lineages". The ability of a differentiated stem cell of one lineage to produce cells of a different lineage is called transdifferentiation. Some types of adult stem cells are more capable of transdifferentiation than others, and for many there is no evidence that such a transformation is possible. Consequently, adult stem therapies require a stem cell source of the specific lineage needed, and harvesting and/or culturing them up to the numbers required is a challenge.

Famous quotes containing the words adult, stem and/or cell:
“And I, whose childhood
Is a forgotten boredom,
Feel like a child
Who comes on a scene
Of adult reconciling,
And can understand nothing
But the unusual laughter,
And starts to be happy.”
—Philip Larkin (1922–1986)
