Enhanced Critical Size Defect Repair in Rabbit Mandible by Electrospun Gelatin/β-TCP Composite Nanofibrous Membranes

Figure 5

Representative immunostaining micrographs of osteocalcin (OCN) at site of defect after 4 weeks ((a)–(c)) and 12 weeks ((d)–(f)) of implantation: untreated group ((a), (d)), gelatin group ((b), (e)), and gelatin/β-TCP group ((c), (f)). The arrows denote positive expression of OCN. M, material and NB, nascent bone; scale bar: 50 μm.
