| Over the past five years, he has studied spermiogenesis as a major determinant of the genetic integrity of the male gamete. |
|
| Knowledge of spermiogenesis in reptiles, especially in lizards, is very limited. |
|
| Thus, PP1γ2 might have a fundamental, isoform-specific role in mammalian spermiogenesis. |
|
| This distribution pattern at the beginning of spermiogenesis was not observed in O. tankahkeei. |
|
| There were severe disturbances in spermiogenesis and atrophy of the prostate gland in all treatment groups. |
|
| Thymus involution was also noted as well as atrophy of lymphoid follicles and lymph nodes, absent spermiogenesis, and increased centrolobular fat in the liver. |
|
| The most dramatic change in chromatin composition is observed during spermiogenesis where nucleosomal chromatin is transformed into nucleoprotamine fiber. |
|
| Although spermiogenesis and spermatozoan morphology are similar among most insect species, many species also exhibit certain distinctive characteristics. |
|
| Chromatin structure anomalies usually appear during spermiogenesis. |
|
| Nuclear changes during spermiogenesis in two chrysomelid beetles. |
|
| The final step in the developmental process, termed spermiogenesis, is the conversion of a haploid round spermatid to a polarized, flagellated, motile spermatozoon or sperm. |
|
| Spermiogenesis involves the differentiation of spermatids into spermatozoa without further cell division. |
