Abstract: In order to investigate skeletal muscle development mechanism,the expression of follistatin (FST) and fibromodulin (FMOD) gene were comparatively analyzed in fetus different skeletal muscles and different stages between Ujumqin sheep and Texel sheep during early stage.Two gene expression were analyzed including longissimusdorsi,semimembranosus,semitendinosus quadricepsfemoris and biceps femoris muscle were compared by variance analysis methods of four stages (85,100,120 and 135 d).The results of quantitative Real-time PCR showed that the expression of FST gene showed a tendency to increase with the addition of stage,and the expression of FST gene in Texel sheep was higher than that in Ujumqin sheep in semitendinosus (100,120 d),semimembranosus (120 d),and biceps femoris (120 d) (P<0.05).The expression of FST gene in Texel sheep was extremly higher than that of Ujumqin sheep in semitendinosus (100,135 d),longissimusdorsi (85 d),quadricepsfemoris (100 d) and biceps femoris (100 d) (P<0.01).As a whole,the expression of FMOD gene was the highest in quadriceps femoris,and was lower in other four muscles,it's expression in Ujumqin sheep was higher than that in Texel sheep.It was inferred that FST and FMOD genes might be related to muscle development during early stage.
