OCT4B1 Regulates the Cellular Stress Response of Human Dental Pulp Cells with Inflammation

Figure 1

Expression of OCT4B1 in the dental pulp tissues with inflammation. (a) HE indicated that odontoblasts lined along the pulp-dentin border below which the tubular dentin was regularly presented in noninflamed pulp (×200). (b) Odontoblasts were disorderly arranged with inflammatory cell infiltration in the inflammatory pulp-dentin complex (×200). ((c) and (e)) In situ hybridization assay revealed that, in the noninflamed dental pulp tissues, OCT4B1 (white arrows) was weakly expressed in the cytoplasm of DPCs (×200, ×400), whereas OCT4B1 was expressed in both the cytoplasm and nucleus of the inflamed DPCs ((d) and (f), ×200 and  ×400).
