Bioactive Cellulose Acetate Electrospun Mats as Scaffolds for Bone Tissue Regeneration

Figure 5

(a) hFOB 1.19 BrdU cell proliferation assay against each CA electrospun mat. Blue nuclei represent total cells, and orange overlap represents the BrdU-incorporated nuclei in (A) CA fiber mat, (B) CA-KRSR, (C) CA-RGD, (D) CA-BMP-2, and (E) CA-MP. Scale bar represents 50 µm. (b) BrdU-positive cells in each treated fiber mat.
