TLDR Vesicles from irradiated mouse cheek skin help cells survive radiation.
The study investigated the protective effects of exosome-like vesicles (ELV) secreted from irradiated neonatal mouse cheek skin on hair follicle loss after high-dose radiation. Neonatal mice exposed to 7 Gy X-ray showed overall hair growth defects except on their cheeks, suggesting a protective substance was secreted. The researchers found that ELV from irradiated cheek skin increased cell survival in mouse fibroblast cell lines, indicating that these vesicles might help prevent hair follicle loss after radiation exposure.
