Figure 1. DMP1 is expressed in the processes of odontoblasts and the dendrites of osteocytes. (a) Dmp1-lacZ staining. The freshly isolated incisor from a 10-day-old Dmp1 lacZ knock-in pup was stained with x-gal overnight at 37° C, followed by sectioning and counter-staining with methyl green. Note the lacZ staining, reflecting endogenous Dmp1 expression. (b) DMP1 immunostaining of a 10-day-old incisor. The lower incisor was decalcified and processed for immunohistochemistry staining with an affinity-purified polyclonal antibody against DMP1 C-terminal. (c) DMP1 immunostaining of a 10-day-old long bone. DMP1 is highly expressed in dendritic processes and the canaliculi of osteocytes.

Figure 2. E-11 is highly expressed in both the processes of odontoblasts and dendrites of osteocytes. A 10-day-old mandible was stained with a polyclonal antibody against E-11. E-11, a membrane protein used as a marker for newly formed osteocytes, can be detected in odontoblast processes and dentinal tubules, as well as in osteocytes in alveolar bone.
