Figure 3

HBMSCs attachment on the PDL60/Col and PDL60/Gel electrospun scaffolds. (a, b) are SEM images of PDL60/Col scaffolds and PDL60/Gel scaffolds, respectively. (c, d) are maximum projection fluorescence images of PDL60/Col and PDL60/Gel cell-scaffold constructs, respectively. (e) Cell numbers were counted based on the confocal images (originally adapted from [69]). ^∗∗∗PDL60.
