Image 2: Differentiation process of stem cells into nerve cells. The source of the photo: Sharon*. Human embryonic stem cells grown in cell culture on fibroblasts of human origin. The stem cells are grown on a layer of cells that are used as a feeder layer (on the "feeder layer" left picture). In order to make them differentiate, they are collected and grown as a cluster of cells in suspension (central image), and various substances are added to them that cause them to differentiate into neurons (right image, after 10 weeks of sorting - dyed with a special fluorescent dye green - nerve cells. Blue - the cell nuclei).

How does the process take place in which stem cells acquire their specialization, and become mature cells?
