Definitions for "Transdifferentiation"
The ability of a particular cell of one tissue, organ or system, including stem or progenitor cells, to be caused to differentiate into a cell type characteristic of another tissue, organ, or system; e.g., HSC to liver hepatocytes.
Direct differentiation of one type of cells to another
When adult stem cells from one type of tissue grow into cells of another type. An example of this would be stem cells from bone marrow, which are already partially developed to be blood cells, growing into heart cells when they are injected into the heart.
