Figure 6. BMP9 inhibited the progression of early pulpitis in rats. (A–F) H&E showed the location and extent of pulpitis in the group treated with LPS+HCl and it was greater than in the other two groups. (H–M’) IHC results showed that IL-6 and IL-8 were mainly expressed in the inflammatory region and the expression range and level of IL-6 and IL-8 in the group treated with LPS+HCl were higher compared with the other two groups.
