Are the proteins underlying differentiation of cells in embryogenesis similar to the proteins, regulating differentiation of the newly formed neurons in adult brain, or they are quite different proteins?
Sang Ho Lee
Well-known and conserved signals in embryogenesis appear over and over again during different time of a specific generation of cell lineage when it's necessary. The only difference is the niche that includes distance within the tissue, vascular system containing hormones, nutrients, certain immune response, and physical activity, These factors will either stimulate or repress the developmental signals.
