Definition of spermatid in English:

spermatid

nounˈspəːmətɪdˈspərməˌtid

Biology

An immature male sex cell formed from a spermatocyte, which may develop into a spermatozoon without further division.
Example sentencesExamples
- Three trained observers reviewed each stallion's histology slides by quantifying the number of spermatids within 25 cross-sectioned round seminiferous tubules.
- The hypothesis was confirmed in experiments using phase-contrast microscopy, which showed the presence of individualized spermatids in the mutant testes.
- Rates of protein evolution were fastest for genes expressed during the dramatic morphogenesis of round spermatids into spermatozoa.
- These haploid cells - now called spermatids - thus contain 23 single half chromosomes.
- Spermatocytes, the progenitors of spermatids, are biosynthetically active cells, producing all the components that will be needed in the mature spermatozoa.

Derivatives

spermatidal

adjectiveˌspəːməˈtʌɪd(ə)l

Biology

Rat spermatidal protein TP2 is rich in serine residues and has several potential sites for phosphorylation by different protein kinases.
Example sentencesExamples
- Two novel zinc fingers have been discovered in the mammalian spermatidal protein TP2, which recognizes human CpG islands in a zinc dependent manner.
- Possible functions for high HMGA2 levels may include role in testis-specific events such as genetic recombination, meiotic divisions, or replacement of histones by late spermatidal basic proteins during nuclear condensation.
