Pig semen exosomes shown to shuttle chemo to back-of-eye cancer in mice
Researchers used semen-derived exosomes from pig semen to deliver a chemotherapy-like payload to the retina in a mouse model of retinoblastoma, via eye drops. The approach successfully reached the back of the eye and reduced tumor size after 30 days, suggesting a potential noninvasive treatment route for this pediatric eye cancer, though safety and effectiveness in humans remain to be tested in trials.
