Cell growth & differentiation
WebDifferentiation is the process by which unspecialized cells become specialized to carry out distinct functions. Stem Cells A stem cell is an unspecialized cell that can divide without limit as needed and can, under specific conditions, differentiate into specialized cells. WebDifferentiation is the complex process that leads to diversity in cell properties (that is, what the cell actually is and does, the cell’s phenotype, which is often characterized by the physical appearance of the cell and the contents of its cytoplasm) from a population of cells with the same genotype (that is, the same genetic material).
