In vivo experimental design. a Photographs of the experimental implant (left panel) and implant in the rat oral cavity (right panel). b Experimental protocol of in vivo study: Implantation was performed at the same time as tooth extraction, then 1 day after implantation, mesenchymal stem cells (MSCs) were injected via the tail vein or into the gingivobuccal fold around the dental implant. Epithelial tissue structure around the implant was observed after 4 weeks. MSC accumulation into various tissues was observed 1, 3, 5, and 7 days after MSCs injection. c Photograph of MSC administration into the model rat with the experimental implant
