Aiming at identification of tissue and species origin of mammalian cell lines collected at Ivanovsky Institute of Virology, Russian Academy of Medical Sciences, we analyzed 31 cell lines initially isolated in the institute or donated by collaborators. The species-specific polymerase chain reaction...

Inclusion of compounds containing selenium to the ration of hens influences positively the hystogenesis of bursa cloacalis of hens that is manifesting in the extension of surfaces and cortical substance of follicles. Besides that the control group had the most striking involutional processes that...

In the paper the questions of perspective directions of studying of the mechanism of damage of reproductive cells of fish after storage at ultralow temperature are discussed. The necessity of the morphological analysis of generative cells of fish before freezing at a cellular and subcellular level, ...

Bovine embryos at stage of development 7-8 days were estimated morfologically after nonsurgical recovery. Repeated morfological estimation was carried out after cryopreservation and thawing. The prediction of the pregnancy rate after transplantation of thawed embryos was made by the comparison of...
