Medical Oddities: Pig Semen, Meet Eye Drops

Evolution, sex, soil, and diets—this lineup covers a little bit of everything.

1

Investigators used pig semen-derived exosomes as eye drop carriers, achieving significant corneal penetration in mouse models.
2

The engineered exosomes inhibited tumor cells by 83% in vitro and reduced retinoblastoma burden to 2.35% of control levels in vivo.
3

Treatment with these eye drops induced oxidative stress and apoptosis in tumor cells while preserving retinal function.
4

The drops showed minimal toxicity and cleared within 24 hours, presenting a novel approach to ophthalmic drug delivery.
5

This study highlights innovative uses of biological materials in medicine, showcasing unexpected advancements in treatment methods.
