J. Mol. Sci. 2020, 21,25 ofFurthermore, several studies showed that some members from the TGF- superfamily promote RANKL-induced osteoclast differentiation (Table two). One example is, Itoh et al. located that RANKL is expected to observe any osteoclast differentiation of mouse bone marrow macrophages inside the presence of rhBMP-2 (300 ng/mL), given that adding rhOPG prevents osteoclastogenesis [333]. Within the very same way, both rhBMP-2 and rhBMP-7 favor the osteoclastogenesis in the RAW264.7 cells within the presence of rhRANKL (50 ng/mL). On the other hand, though rhBMP-2 (550 ng/mL), inside the presence of RANKL, dose dependently increases the calcium phosphate resorption location compared to rhRANKL alone, rhBMP-7 induces much less bone resorption at 150 ng/mL than at 5 ng/mL, after 7 days [326]. The rhBMP-2/7 heterodimers (550 ng/mL) also boost the RANKL-mediated osteoclastogenesis [326]. Precisely the same observation was done working with rhBMP-9, the cytokine at doses varying from 50 to 150 ng/mL, enhanced the osteoclast differentiation of mouse spleen macrophages induced by rhRANKL (one hundred ng/mL) [265]. The authors suggested that BMP-9 inhibits the intracellular ERK1/2 pathways to favor the osteoclastogenesis [265]. Applying human.
