The ECM was intact and undisrupted in cPDLSC sheets. Macroscope of cPDLSC sheet (a) and fPDLSC sheet (f) shows that their “sheet-like” structures were intact. H&E staining of cPDLSC sheets (b) and fPDLSC sheets (g) showing a uniform and multilayer tissue structure. Visualization of type I collagen (COLI; c), fibronectin (d), and integrin (e) in cPDLSC sheets by immunostaining. Visualization of type I collagen (h), fibronectin (i), and integrin (j) in fPDLSC sheets by immunostaining. Scale bars = (b,g) 20 μm; (c–e, h–j) 25 μm. Magnification: (b, g) 40×; (c–e, h–j) 100 ×
