Fig. 6: Immunofluorescence staining of 3D model.

a Immunofluorescence staining of sarcomere with the primary antibodies of CD31, WT1, cTNT, and α-actinin in 3D-model. b–e The fluorescence intensity was calculated by Fiji/ImageJ and normalized to cell counts. b CD31, c cTNT, d WT1, e α-actinin. * indicates p < 0.05. ns indicates no significance. n = 3 biological replicates for all groups.
