Fibrodysplasia ossificans progressiva is characterized by extensive ossification
within muscle tissues, and its molecular pathogenesis is responsible for the
constitutively activating mutation (R206H) of the bone morphogenetic protein type
1 receptor, activin-like kinase 2 (ALK2). In this study, we investigated the
effects of implanting ALK2 (R206H)-transfected myoblastic C2C12 cells into nude
mice on osteoclast formation during heterotopic ossification in muscle and
subcutaneous tissues. The implantation of ALK2 (R206H)-transfected C2C12 cells
with BMP-2 in nude mice induced robust heterotopic ossification with an increase
in the formation of osteoclasts in muscle tissues but not in subcutaneous
tissues. The implantation of ALK2 (R206H)-transfected C2C12 cells in muscle
induced heterotopic ossification more effectively than that of empty
vector-transfected cells. A co-culture of ALK2 (R206H)-transfected C2C12 cells as
well as the conditioned medium from ALK2 (R206H)-transfected C2C12 cells enhanced
osteoclast formation in Raw264.7 cells more effectively than those with empty
vector-transfected cells. The transfection of ALK2 (R206H) into C2C12 cells
elevated the expression of transforming growth factor (TGF)-?, whereas the
inhibition of TGF-? signaling suppressed the enhanced formation of osteoclasts in
the co-culture with ALK2 (R206H)-transfected C2C12 cells and their conditioned
medium. In conclusion, this study demonstrated that the causal mutation
transfection of fibrodysplasia ossificans progressiva in myoblasts enhanced the
formation of osteoclasts from its precursor through TGF-? in muscle tissues.
