Table 2 Microenvironment and stem cell plasticity.

From: The universal stem cell

1. SL/SLd – Genetic model of stromal insufficiency

2. Physical location of hematopoiesis

3. CFU-s Dexter and Whitlock-Witte stromal cultures

4. Plasticity: Engrafted marrow stem cells giving rise to non-hematopoietic cells in different organs—lung, heart, brain, etc.
