Multinucleate spermatogenic cells by traumatic haemorrhagic suffusion in lizard testes
Virchows Archiv. B, Cell Pathology
|September 11, 1975
Summary
Trauma-induced testicular hemorrhages in lizards caused multinucleate cells. These cells, formed by cell fusion or nuclear division without cytokinesis, suggest hypoxia as a cause of spermatogenic alterations.
Area of Science:
- Reproductive Biology
- Herpetology
- Cell Biology
Background:
- The study investigates testicular alterations in the tropical teiid lizard, *Cnemidophorus 1. lemniscatus*.
- Hemorrhagic suffusions were observed in testes, presumed to be from capture-related trauma.
Purpose of the Study:
- To examine the cellular effects of testicular trauma in *Cnemidophorus 1. lemniscatus*.
- To elucidate the formation and potential causes of multinucleate spermatogenic cells.
Main Methods:
- Testes from affected lizards were immediately collected post-autopsy.
- Light microscopy was used to examine testicular tissue structure and cellular morphology.
Main Results:
- Extravasated blood was confined to interstitial spaces.
- Numerous multinucleate spermatogenic cells were observed in seminiferous tubules near hemorrhages.
- Nuclei within multinucleate cells were in the same developmental stage, with divisions occurring independently.
Conclusions:
- Multinucleate cell formation is likely due to cell fusion via cytoplasmic interconnections, possibly augmented by nuclear division without cytokinesis.
- Local circulatory disturbances, particularly hypoxia, are implicated as the cause of these observed cellular alterations.
