PRX1⁺ cells in the reconstruction of PDL. a–c PDL and blood vessels of WT mice (a), Prx1-cre; R26R^tdTtomato mice (b), tooth replantation model mice (c), respectively. c,d Recipient PRX1⁺ cells (labeled in red) migrated to the PDL of the implanted WT M1 to form new blood vessels, and white arrows in c3 and d1 point to the new angiogenesis in WT PDL, white arrowheads point to migrated PRX1⁺ cells. d2, Schematic diagram of PRX1⁺ cells involved in angiogenesis as pericyte during the restoration of PDL. n = 18 in tooth transplantation model (including Fig. 5 and Fig. 6)
