Fig. 4From: Therapeutic potential of small extracellular vesicles derived from lipoma tissue in adipose tissue regeneration—an in vitro and in vivo studysEV-LT promotes adipose tissue regeneration in vivo. a Histology of Matrigel group, sEV-LT group, and sEV-AT group sections at weeks 2, 4, 8, and 12 after transplantation. Sections were stained with hematoxylin and eosin. b Comparison of the average adipocyte areas in experimental and control groups at 2, 4, 8, and 12 weeks after transplantation (n = 4). c Comparison of the mean capillary numbers of neotissue sections in the experimental and control groups at 2, 4, 8, and 12 weeks (n = 4).
