Abstract:
:Myostatin (GDF-8) inhibits the activation, proliferation, and differentiation of myogenic satellite cells. The relative importance of this growth factor is demonstrated in myostatin-null mice and cattle possessing defective myostatin genes. These defects result in greatly enhanced musculature. In the present study, the effect of myostatin on chicken myogenic satellite cells derived from two different skeletal muscles was studied. The effect of anti-myostatin antibodies on cellular responses was also examined. Satellite cells isolated from the pectoralis major (PM) muscles were more responsive to the proliferation depressing effects of myostatin compared to cells from the biceps femoris (BF; P
