#Unit 5. Developmental Biology

If a stem cell divides symmetrically, have the ability to produce either two stem cells (increasing the stem cell pool by one) or two committed cells (decreasing the pool by one). This is called symmetrical renewing or symmetrical differentiating.

If a stem cell divides asymmetrically, produce two types of cells (a stem cell & a developmentally committed cell) are produced at each division, is called the single stem cell asymmetry.
