Are there more stem cell populations to be discovered and, if so, is it possible that all undifferentiated epidermal cells are stem cells?

Of particular promise in that regard are stem cells, which could help repair damaged CNS structures.
A number of these cells are stem cells, but the majority are transit amplifying cells.
Barkauskas, C. E. et al. Type 2 alveolar cells are stem cells in adult lung.
At the base of the epidermis are stem cells which use sticky proteins called collagen to secure the epidermis to the layer below.
The team used whole genome sequencing to study induced pluripotent stem cells lines (iPS), which are stem cells developed from a mature-differentiated cell.
If many of a tumor's cells are stem cells, then existing chemotherapy agents are clearly killing them, Dr. Vogelstein said, and the cancer stem cell theory is not an effective guide to finding new drugs.
In September, Japanese doctors performed the first transplant of retinal tissue derived from so-called iPS cells, which are stem cells that can be created from a person's own tissue and match them genetically.
Since the late 1990s, scientists have held out the prospect of extraordinary new treatments from pluripotent stem cells, which are stem cells that can grow into all sorts of different tissues at researchers' urging.
