Detailed explanation-1: -Cell differentiation is the process by which cells become specialized in order to perform different functions.
Detailed explanation-2: -Cell differentiation is a process by which a particular cell becomes specific or specialized. In the human body stem cells can differentiate multiple cell types, as these cells can continuously divide to differentiate into different cell types.
Detailed explanation-3: -Cell specializations make it possible to express fewer genes in individual cells of multicellular organisms, thus protecting genes from the damage of mutagens.
Detailed explanation-4: -The process of hematopoiesis involves the differentiation of multipotent cells into blood and immune cells. The multipotent hematopoietic stem cells give rise to many different cell types, including the cells of the immune system and red blood cells.
Detailed explanation-5: -The process of differentiation occurs when different genes in the genome are expressed or repressed. This process occurs through the signal transduction pathway, a way of transmitting extracellular signals to cause changes in cell function.
