Fig. 7From: Exosomes secreted by stem cells from human exfoliated deciduous teeth contribute to functional recovery after traumatic brain injury by shifting microglia M1/M2 polarization in ratsSchematic of SHED-Ex repair of impaired CNS: SHED-Ex shifts microglia M1/M2 polarization. SHED-Ex contact with activated microglia to promote robust M2 polarization. As a result, anti-inflammatory cytokines were released to repair.
