Stem cells can divide indefinitely and can produce different types of cells, as shown in the model here. A student wants to revise the model to accurately depict how stem cell division and differentiation allows for specialized cells to develop while maintaining the ability for the stem cell to give rise to new cells. What revision to the model best depicts stem cell division and differentiation? A) The model should show apoptosis of the white blood cells that are unnecessary to the immune system. B) The model should show the original stem cell dividing to become a differentiated cell and another stem cell. C) The model should show the process of meiosis before cell differentiation since specialized cells are haploid. D) The model should show the reversion of the white blood cell back into a stem cell so that future differentiation can occur.
