The commitment of cells to specific cell fates and their capacity to differentiate into particular kinds of cells. Positional information is established through protein signals that emanate from a localized source within a cell (the initial one-cell zygote) or within a developmental field.

The formation from simpler components of any hormone, naturally occurring substances secreted by specialized cells that affects the metabolism or behavior of other cells possessing functional receptors for the hormone.

major histocompatibility complex class I receptor

A major histocompatibility complex class I receptor. These display processed antigens from the endocytosed bacteria. MHC class I proteins can form complexes with processed antigen peptides only if the antigen is synthesized in the same cell. As a consequence, T lymphocytes can only bind to class-I-positive cells that are synthesizing the antigen (e.g. virus-infected cells).

The breakdown into simpler components of any hormone, naturally occurring substances secreted by specialized cells that affects the metabolism or behavior of other cells possessing functional receptors for the hormone.

The chemical reactions involving progesterone, a steroid hormone produced in the ovary which prepares and maintains the uterus for pregnancy. Also found in plants.

cell-cell signaling involved in cell fate commitment

cell-cell signalling involved in cell fate commitment

Signaling at long or short range between cells that results in the commitment of a cell to a certain fate.

Catalysis of the reaction: 3-phospho-D-glyceroyl phosphate = 2,3-bisphospho-D-glycerate.

An increase in size of a blastocyst due to expansion of the blastocoelic cavity cell shape changes and cell proliferation.

Catalysis of the reaction: 2,3-diphosphoglycerate + H2O = 3-phosphoglycerate + phosphate.

The proliferation of cells in the inner cell mass.

branched-chain amino acid aminotransferase activity

Catalysis of the reaction: L-leucine + 2-oxoglutarate = 4-methyl-2-oxopentanoate + L-glutamate.
