Western Blot for MMP1. (A) MMP1 expression of HFs and MG-63 cells independently grown and (B) co-cultured. (C) Densitometric analysis of MMP1 expression relative to HFs and MG-63 cells independently grown and co-cultured. *represents a significant difference from the HF control sample, P < 0.05. # represents a significant difference from the MG-63 control cells, P < 0.05.
