The transcription factor of one type of these is encoded by Oct-4, which in a certain species disappears without the presence of leukemia inhibitory factor.  That same type can develop into a teratoma if grafted onto normal tissue, while another type can be found in places like the olfactory bulb and hippocampus.

Hematopoietic ones, which were discovered in 1963, and mesenchymal ones are present in bone marrow. A 2006 study co-authored by Robert Lanza suggests that certain ones restore visual function in dystrophic rats, and they are called pluripotent if they can develop into any derivative of the three primary germ layers. FTP, identify this type of undifferentiated cell that comes in adult and embryonic varieties.
