Presence and distribution of TNF-α and IL-1β in the prostate tissue were analyzed by immunohistochemical staining (scale bar: 20 μm).
Representative images of TNF-α staining in the (a) CBP, (b) ultrasound, (c) BMMSCs and (d) MMUS groups. Red arrows highlight TNF-α staining. Representative images of IL-1β staining in the (e) CBP, (f) ultrasound, (g) BMMSCs and (h) MMUS groups. Black arrows highlight IL-1β staining. i) Mean optical densities (mean ± SD) of the TNF-α and IL-1β staining from four rats per group. * and #P<0.05 vs. the CBP, ultrasound and BMMSCs groups.
