Fig. 5From: Immunosuppressive effect of mesenchymal stem cell-derived exosomes on a concanavalin A-induced liver injury modelHistological findings of the liver at in vivo experiment with exosomes derived from MSCs and fibroblasts. Hematoxylin-eosin, Ki-67, and ssDNA staining of the liver of mice received intravenous injections of PBS only (PBS), MSC-derived exosomes once (E0), MSC-derived exosomes three times (E0/8/16), MSCs (MSC), or fibroblast-derived exosomes three times (Fibro_exo)Back to article page
