JAGGED1 modulates bull spermatozoa acrosome reaction and fertilization [PDF]
Reproduction and FertilityTo acquire fertilizing ability, mammalian spermatozoa (SPZ) must undergo acrosome reaction, which is associated with protein remodeling and relocation. Previous studies showed that Notch ligand JAGGED1 is relocated from the apical to the post-equatorial ...

Localization of Acrosomal Proteinase after Vesculation of the Acrosome [PDF]
Development, Growth & Differentiation, 1981 The freshly ovulated egg is covered by the zona pellucida and follicular‐cell layer. The former is reported to dissolved by acrosomal proteinase and the latter may be dispersed by hyaluronidase. If these two enzymes have different targets, two possibilities can be taken into consideration concerning the timing of release of the two enzymes from the ...

Inceptor facilitates acrosomal vesicle formation in spermatids and is required for male fertility
Frontiers in Cell and Developmental Biology, 2023 Spermatogenesis is a crucial biological process that enables the production of functional sperm, allowing for successful reproduction. Proper germ cell differentiation and maturation require tight regulation of hormonal signals, cellular signaling ...

STUDIES ON THE ACROSOME. X. DIFFERENTIATION OF THE STARFISH ACROSOME* [PDF]
Development, Growth and Differentiation, 1971 The course of acrosomal differentiation observed during spermiogenesis in two starfishes shows that the central components of the mature acrosome are produced by Golgi activity. In the early spermatid, small Golgi-derived vesicles enter the hydrated acrosomal mass and appear to contribute their membrane constituents to the acrosomal-membrane precursor ...
