Figure 9.

(a) Preparation scheme of BP-BG composite scaffolds. (b) Infrared thermographic photographs of osteosarcoma-bearing nude mice implanted with BG and BP-BG scaffolds. (c) Tumor growth curves of mice after different treatments. (d) Photographs of osteosarcoma-bearing mice after different treatments on day 14. (e) Micro-CT imaging after treatment for 8 weeks. The defect areas were implanted with BP-BG and BG scaffold, respectively. (f) Stepwise therapeutic strategy for the elimination of osteosarcoma followed by osteogenesis in BP-BG composite scaffolds. Reproduced with permission [162]. (g) Preparation scheme of nanofibrous scaffolds and the underlying mechanisms of PTT/chemotherapy and tissue regeneration. (h) Representative images of the tumors on days 0, 4, 8, 12 and 15 after treatment with control (I), GP (II), GP+laser (III), 5BP-PEG-FA-GP (IV), 5BP-PEG-FA-GP+laser (V), 5BP@DOX-PEG-FA-GP (VI) and 5BP@DOX-PEG-FA-GP+laser (VII). (i) Representative images of dermal wounds in different treatment groups on days 0, 4, 8, 12 and 15. The treatments include control (I), GP(II), 5BP-PEG-FA-GP (III) and 5BP@DOX-PEG-FA-GP (IV).
