This figure indicates normal histological structure in the negative control (A), showing parakeratosis (black arrow), infiltration of dermis by high number of mononuclear inflammatory cells (blue arrow) with sever edema(arrow head) in the untreated samples (positive control) (B), showing parakeratosis (black arrow) with normal histological structure of epidermis and dermis in the treated group with Mesenchymal stem cells (C), showing parakeratosis (black arrow), infiltration of dermis by few number of mononuclear inflammatory cells (blue arrow) with mild edema (arrow head) in the sample treated with EGCG Nanoparticles (D). While a mild parakeratosis (black arrow) with mild infiltration with mononuclear inflammatory cells was observed in the samples treated with exosomes (E). The photomicrograph of the treated group, EGCG Nanoparticles loaded into Exosomes (F), shows normal histological structure of dermis and epidermis.
