From: BACH1 regulates the proliferation and odontoblastic differentiation of human dental pulp stem cells

Fig. 1

BACH1 was mainly located in the odontoblast layer of human dental pulp tissues. a Immunohistochemical staining was performed to show the BACH1 expression in healthy human dental pulp tissues; arrowheads indicate BACH1 expression. Scale bars = 50 µm. b BACH1 (red) and HO-1 (green) expression was detected by double immunofluorescence staining. Blue, DAPI-stained cells. c Positive cell rate analysis indicated that the expression of BACH1 and HO-1 increased in the odontoblast layer (red) compared with the cell rich zone (yellow). Scale bar = 20 µm. Data were presented as the mean ± standard error of the mean (n = 7). **P < 0.01, ***P < 0.001
