WebPTHrP is produced by the enamel organ and loss of PTHrP leads to a lack of postnatal tooth eruption, a classic result of aberrant osteoclastogenesis (Philbrick et al., 1998 ). Replacement of PTHrP in the enamel epithelial cells allows tooth eruption. Further studies have revealed that PTHrP drives osteoclasts to resorb bone to form crypts as a ...
