Definition of spermatogonium in English:

spermatogonium

nounPlural spermatogoniaspəˌmatə(ʊ)ˈɡəʊnɪəmˌspəːmətə(ʊ)ˈɡəʊnɪəmspərˌmatəˈɡōnēəm

Biology

A cell produced at an early stage in the formation of spermatozoa, formed in the wall of a seminiferous tubule and giving rise by mitosis to spermatocytes.
Example sentencesExamples
- The primitive germinal cells are the spermatogonia, which lie peripherally in the tubule wall, outside the barrier of Sertoli cell junctions.
- Males are consequently exposed to new antigens when spermatogonia mature, and the immune activity involved in the male reproductive system may lead to autoimmunity.
- In the testis, these cells are termed the spermatogonia.
- A primary spermatogonium surrounded by a pair of cyst cells undergoes four mitotic divisions, forming a cyst of 16 primary spermatocytes.
- In severely degenerated tubules, only spermatogonia and Sertoli cells were observed, and pachytene spermatocytes sloughing into the lumen were observed.

Derivatives

spermatogonial

adjective

Biology

Because they can now grow spermatogonial stem cells in culture, researchers have a ready source of cells that they could manipulate genetically, explained the study's senior author.
Example sentencesExamples
- In addition, the testes contained highly refractile cysts that most likely represent degenerating cysts of spermatogonial cells.
- A maximum of 50 offspring were tested from each ENU-treated male to prevent the recovery of identical mutations from the limited population of spermatogonial stem cells.
- In previous studies, longitudinal evaluation of F 2 chimeric males revealed evidence of chimeric drift with selection against the germline having a history of Type B spermatogonial irradiation.
- At the apical end of the testes, stem cells divide to produce a spermatogonial cell that undergoes four rounds of mitosis to produce 16 primary spermatocytes.

Origin

Late 19th century: from sperm + modern Latin gonium (from Greek gonos 'offspring, seed').
