Transdifferentiation occurs naturally in only a few instances of regeneration.A celebrated example is the Wolffian regeneration of the lens in newts, where removal of the lens of the eye provokes the formation of a new lens derived from the cells of the iris. Cellular differentiation, or simply cell differentiation, is the process through which a cell undergoes changes in gene expression to become a more specific type of cell. What is the difference between Totipotent and Pluripotent. Try the ones that best apply to you, depending on factors such as student age. A stem cell which is capable of giving rise to any kind of differentiated cells in a particular organism is considered as totipotent. Stem cells can, for example, differentiate into secretory cells in the intestine.2 In cancer, differentiation refers to how mature (developed) the cancer cells are in a tumor.
