Western blot analysis of cell lysates and conditioned medium showed comparable amount of FBN in UCMD and control tenocyte cultures, as indicated by densitometric quantification (Figure 5A); COLI was normally expressed in cell lysate, while it was moderately reduced in the patient conditioned medium (Figure 5A). This evidence concerns the gene FBN1 and Congenital muscular dystrophy, Ullrich type.
