The fundamental notion of a stem cell is that it can make more stem cells while also producing cells committed to undergoing differentiation. This process is called as-

A stem cell capable of producing all the cell types of a lineage(embryonic and extraembryonic) is said to be-

after the 8-cell stage, the mammalian embryo develops an outer layer (which becomes the fetal portion of the placenta), and an inner cell mass that generates all the cells of embryo. The cells of the inner cell mass are thus said to be-

cell populations within each germ layer expand and differentiate, resident stem cells are maintained within these developing tissues and function to generate cell types with restricted specificity for the tissue in which they reside. these stem cells are-

Local cell signaling is carried out via membrane receptors that bind to proteins in the extracellular matrix (ECM) or directly to receptors from a neighboring cell in a process called as-

when one group of cells changing the behavior of an adjacent set of cells, thereby causing them to change their shape, mitotic rate, or cell fate. This kind of interaction at close range between two or more cells or tissues of different histories and properties is called as-
