Fig. 1From: Therapeutic effects of human gingiva-derived mesenchymal stromal cells on murine contact hypersensitivity via prostaglandin E2–EP3 signalingCharacterization of human GMSCs. GMSCs showed a spindle-shaped, fibroblast-like morphology a; multilineage differentiation potency including adipogenesis b, as identified by Oil Red O staining; osteogenesis c, as identified by Alizarin Red S staining; chondrogenesis d, as identified by immunohistochemical staining of collagen type II; and colony-forming ability e, as identified by Toluidine Blue stainingBack to article page
