Term
Adult stem cells
Definition
Stem cells that are found in tissues after embryogenesis is complete.
Term
Committed stem cell
Definition
A stem cell that can give rise to a restricted range of related cell types.
Term
Embryonic stem cells
Definition
Cells of the inner cell mass of a mammalian embryo from which all of the cells of the body are derived.
Term
Organogenesis
Definition
During embryogenesis, the generation of body organs.
Term
Pluripotent stem cell
Definition
A stem cell that can generate all of the structures of an embryo, but not the placenta.
Term
Stem cell
Definition
A cell which divides to form one daughter cell that remains a stem cell and one daughter cell that can differentiate to a specific cell type.
Term
Stem cell niche
Definition
Specialized compartments within organs in which stem cells reside and receive from surrounding cells signals related to division and differentiation.
Term
Totipotent cell
Definition
A cell such as a zygote from which all cells of the embryo and, in mammals, the trophoblast are derived.
