Total pulp regeneration 12 weeks after allogeneic transplantation of mobilized dental pulp stem cells (MDPSCs) in pulpectomized teeth in dogs. a–f First transplantation. g–n Second transplantation. a–c, g–j DLA matched transplant. d–f, k–n DLA mismatched transplant. b, e, h, l Newly formed blood vessels (v) in the regenerated tissue. c, f, i, m Odontoblast-like cells (arrows) lining along with the wall of the newly formed osteodentin/tubular dentin (d). j, n Periapical region of the transplanted teeth. Inferior alveolar nerve fiber bundle (n). Hematoxylin and eosin (HE) staining. o Morphometric statistical analysis. Ratio of newly regenerated area to root canal area. Data are mean ± standard deviation (n = 5). Tukey’s multiple comparison test method
