Competition as a negative interaction between two species that depend on the same limiting resource to survive, grow, and reproduce.

Some adult stem cells, such as spermatogonia, are referred to as unipotent stem cells because they function in the organism to generate only one cell type.

Multipotent adult stem cells play major roles in organisms with high regenerative capabilities, such as hydra, axolotl, and zebrafish. one cell type.

#Unit 5. Developmental Biology

Adult stem cells must maintain the long-term ability to divide, be able to produce some differentiated daughter cells, and still repopulate the stem cell pool.

Precise control of the division and differentiation of stem cell types is necessary for building the embryo as well as maintaining and regenerating tissues in the adult. progenitor differentiation through endocrine, paracrine, or juxtacrine mechanisms.

Regulation is highly influenced by the microenvironment that surrounds a stem cell and is known as the stem cell niche.
