Front Vet Sci
. 2025 Feb;
12:1547175.
PMID: 39896847
We have previously reported a difference in the composition of epididymal extracellular vesicles (EVs) between normospermic and teratospermic domestic cats. The objective of the present study was to investigate whether...

Methods Mol Biol
. 2024 Oct;
2861:247-256.
PMID: 39395110
Calcium signaling is a critical regulator of sperm activation and function during the processes of capacitation and fertilization. Here, we describe a combined method for calcium imaging of single, live...

Biol Reprod
. 2024 Aug;
111(5):1056-1070.
PMID: 39190878
Sperm maturation depends on exposure to microenvironments within the different segments of the epididymis, but mechanisms underlying how these microenvironments are produced or maintained are not well understood. We hypothesized...

J Vis Exp
. 2023 Oct;
(200).
PMID: 37902325
Acrosome exocytosis (AE), in which the sperm's single exocytotic vesicle fuses with the plasma membrane, is a complex, calcium-dependent process essential for fertilization. However, our understanding of how calcium signaling...

. 2023 Sep;
109(6):864-877.
PMID: 37694824
The murine epididymis has 10 distinct segments that provide the opportunity to identify compartmentalized cell physiological mechanisms underlying sperm maturation. However, despite the essential role of the epididymis in reproduction,...

PMID: 35346690
Secretion of the acrosome, a single vesicle located rostrally in the head of a mammalian sperm, through a process known as "acrosome exocytosis" (AE), is essential for fertilization. However, the...
