Type I collagen expression after 14 days of cell culture. (a) Immunofluorescent analysis for type I collagen expression and quantification of fluorescence intensity in UC-MSC cultures with and without PEMF exposure for 2 hours/day. (b) Immunofluorescent analysis for type I collagen expression and quantification of fluorescence intensity in UC-MSC cultures with and without PEMF exposure for 4 hours/day. (c) Immunofluorescent analysis for type I collagen expression and quantification of fluorescence intensity in UC-MSC cultures with and without PEMF exposure for 8 hours/day. Indicates the -value (probability value, statistical significance level ) between two specific groups of study, ns: indicates a non significant value.
