Characterization of decellularized porcine oviduct- and uterine-derived scaffolds evaluated by spermatozoa-based biocompatibility and biotoxicity.

Decellularized extracellular matrix (dECM) are widely utilized in regenerative medicine and tissue engineering due to their ability to promote cell growth, proliferation, and differentiation. In reproduction, research is focused on the utilization of these scaffolds to treat pathologies causing reproductive dysfunction or to improve assisted reproduction technologies (ARTs). We developed an efficient protocol employing the immersion-agitation technique to decellularize porcine oviductal and uterine sections, comparing the efficacy of fresh versus frozen treatments.

In vitro exposure of porcine sperm to functionalized superparamagnetic nanoparticles.

Nanotechnology and its applications have advanced significantly in recent decades, contributing to various fields, including reproduction. This study introduces a novel method to label porcine oocytes with nanoparticles (NPs) bound to oviductin (OVGP1, Ov) for use in Assisted Reproductive Technologies (ARTs). Despite promising developments, concerns about NP toxicity in gametes necessitate thorough investigation.

Development of decellularization protocols for female cat reproductive organs.

Decellularization is an innovative method to create natural scaffolds by removing all cellular materials while preserving the composition and three-dimensional ultrastructure of the extracellular matrix (ECM). The obtention of decellularized reproductive organs in cats might facilitate the development of assisted reproductive techniques not only in this species but also in other felids. The aim was to compare the efficiency of three decellularization protocols on reproductive organs (ovary, oviduct, and uterine horn) in domestic cats.
