Stem cell plasticity: A rare cell, not a rare event

Research output: Contribution to journalReview articlepeer-review


Purification to homogeneity for a rare stem cell (SC) population by both function and phenotype is a prerequisite to determine if SCs can change their fate (plasticity). Since cell fate determination has been suggested by both external environmental cues and intrinsic gene regulation, plasticity should be studied using both influences. Different frequencies of marrow SC plasticity may be attributed to either different isolation technologies or different developmental stage SCs with more or less multipotentiality. Tissue-specific SCs may reside in marrow, or alternatively, primitive marrow SC may respond directly to regenerative signals by migration to injury sites and repairing the damaged tissue. It is important to dissect the relationship between primitive/tissue-specific SCs and regenerative signals.
