Ultrastructural, autoradiographic and electrophoretic examinations of Chara tomentosa spermiogenesis [PDF]
Acta Societatis Botanicorum Poloniae, 2014 Ultrastructure of a spermatid nucleus changes many times during spermiogenesis. Condensed chromatin forms irregular clusters during phases I-II, a continuous ring adjacent to a nuclear envelope during phases III-V and a network occupying the whole ...

The deubiquitinase cofactor UAF1 interacts with USP1 and plays an essential role in spermiogenesis [PDF]
iScienceSummary: Spermiogenesis defines the final phase of male germ cell differentiation. While multiple deubiquitinating enzymes have been linked to spermiogenesis, the impacts of deubiquitination on spermiogenesis remain poorly characterized.

Proteomic Analysis of Proteins Involved in Spermiogenesis in Mouse [PDF]
, 2016 Spermiogenesis is a unique process in mammals during which haploid round spermatids mature into spermatozoa in the testis. Its successful completion is necessary for fertilization and its malfunction is an important cause of male infertility.

Running the gauntlet: challenges to genome integrity in spermiogenesis [PDF]
NucleusSpecies’ continuity depends on gametogenesis to produce the only cell types that can transmit genetic information across generations. Spermiogenesis, which encompasses post-meiotic, haploid stages of male gametogenesis, is a process that leads to the ...

HIPK4 is essential for murine spermiogenesis
eLife, 2020 Mammalian spermiogenesis is a remarkable cellular transformation, during which round spermatids elongate into chromatin-condensed spermatozoa. The signaling pathways that coordinate this process are not well understood, and we demonstrate here that ...

Comparative aspects of mammalian spermiogenesis. [PDF]
Scanning electron microscopy, 1986 The testes of some different orders of eutherian mammals were examined by conventional electron microscopy with respect to their pattern of spermiogenesis. In addition, some of the testes were studied by cytochemical methods for demonstration of certain nuclear proteins and of glycoproteins in the acrosome and the plasma membrane of spermatids.

Dynamic profiles and transcriptional preferences of histone modifications during spermiogenesis [PDF]
, 2020 During spermiogenesis, extensive histone modifications take place in developing haploid spermatids besides morphological alterations of the genetic material to form compact nuclei.

Morphological Description and Analysis of Octopus rubescens Testis and Sperm [PDF]
, 2021 The male reproductive system in cephalopods is a topic rarely studied in the field of fertilization biology. The changes the sperm cell undergoes during spermiogenesis varies slightly across the animal kingdom and unravelling the process as it occurs ...

Folia Histochemica et Cytobiologica, 2008 Spermiogenesis in Chara algae, which has been divided into 10 phases (sp I-X), is similar to spermiogenesis in animals. The most important process during spermiogenesis in animals is remodeling of chromatin leading to "sleeping genome", being the result ...

The impact of autophagy in spermiogenesis
Asian Journal of Andrology, 2017 Autophagy is an evolutionarily conserved self-digestion process which is essential to keep basal homeostasis in a cell. During this process, degradation and recycling of many cytoplasmic components including the long-lived, unnecessary or aggregated proteins and damaged organelles is achieved through lysosomal machinery.
