“…Despite the ectomesenchyme origin of these cells, the DPSCs exhibit all the criteria for defining MSCs, as defined by the International Society of Cellular Therapy [ 22 ] (ISCT). These characteristics can be related to the biological function of these cells, which are responsible for the maintenance and repair of the periodontal tissue [ 23 ], supporting the DPSC application in dentistry for the regeneration of tooth structures [ 24 , 25 , 26 ] and neurogenesis [ 27 , 28 ]. Based on this, we investigated here, for the first time, the therapeutic potential of human immature dental pulp stem cells (hIDPSCs) for the treatment of AA in a mouse model for AA because the safety and therapeutic potential and multifunctionality of these cells have previously been demonstrated [ 20 , 21 , 29 , 30 , 31 , 32 , 33 ].…”
