An internal scaffold supports microtubule architectural diversity in Xenopus spermatids

It is established that an organized microtubule network is present in Xenopus spermatids and shares key architectural and molecular hallmarks of the mammalian manchette, and a large structural heterogeneity of spermatid microtubules is uncovered, suggesting an internal reinforcement mechanism necessary for extensive nu...

Deciphering Gamete Differentiation in Ostrea edulis using Laser Capture Microdissection and RNA-seq

This study showed that gonia cells represent an immature, proliferative, and highly plastic germ-cell population, with a transcriptomic program largely shared between the male and female developmental pathways, and characterized that early oocyte development is associated with activation of meiotic, cell-cycle, proteos...

An internal scaffold supports microtubule architectural diversity in Xenopus spermatids

During spermiogenesis, early round spermatids differentiate into specialized spermatozoa through an extensive reshaping of the nucleus driven by coordinated cytoskeletal and chromatin-based mechanisms. In mammals, this process critically relies on the transient manchette, a microtubule-based structure that remodels the...
