The process of formation of spermatozoa, including spermatocytogenesis and spermiogenesis.

The process whose specific outcome is the progression of a male gamete over time, from initial commitment of the cell to a specific fate, to the fully functional differentiated cell.

positive regulation of T-helper 2 cell differentiation

Any process that activates or increases the rate of T-helper 2 cell differentiation.

Catalysis of the release of ammonia or one of its derivatives, with the formation of a double bond or ring. Enzymes with this activity may catalyze the actual elimination of the ammonia, amine or amide, e.g. CH-CH(-NH-R) = C=CH- + NH2-R. Others, however, catalyze elimination of another component, e.g. water, which is followed by spontaneous reactions that lead to breakage of the C-N bond, e.g. L-serine ammonia-lyase (EC:4.3.1.17), so that the overall reaction is C(-OH)-CH(-NH2) = CH2-CO- + NH3, i.e. an elimination with rearrangement. The sub-subclasses of EC:4.3 are the ammonia-lyases (EC:4.3.1), lyases acting on amides, amidines, etc. (EC:4.3.2), the amine-lyases (EC:4.3.3), and other carbon-nitrogen lyases (EC:4.3.99).

Catalysis of the release of ammonia by the cleavage of a carbon-nitrogen bond or the reverse reaction with ammonia as a substrate.

The specialization of the spermatid nucleus during the development of a spermatid into a mature male gamete competent for fertilization.

Catalysis of the release of amides or amidines by the cleavage of a carbon-nitrogen bond or the reverse reaction with an amide or amidine as a substrate.

The process whereby a relatively unspecialized cell acquires specialized features of a muscle cell.

The breakdown into simpler components of glycerol, 1,2,3-propanetriol, a sweet, hygroscopic, viscous liquid, widely distributed in nature as a constituent of many lipids.

Catalysis of the elimination of H2S or substituted H2S.

regulation of myeloid cell differentiation

Any process that modulates the frequency, rate or extent of myeloid cell differentiation.
