Abstract (original English)
To investigate the application of tissue-engineering bone with ADSCs (adipose-derived stem cells) and coral scaffold for repairing of cranial bone defect in canine. Autologous ADSCs isolated from canine subcutaneous fat were expanded, osteogenically induced, and seeded on coral scaffolds. Bilateral full-thickness defects (20 mm x 20 mm) of parietal bone were created (n = 7). The defects were either repaired with ADSC-coral constructs (experimental group) or with coral alone (control group). Radiological, gross, biomechanical and histological observations were done to evaluate the bone regeneration. Three-dimensional CT scan showed that new bones were formed in the experimental group at 12 weeks after implantation, while coral scaffolds were partially degraded in the control group. By radiographic analysis at 24 weeks post-transplantation, it showed that an average repair percentage of each defect was (84.19 +/- 6.45)% in experimental group, and (25.04 +/- 18.82)% in control group (P < 0.01). The maximum compression loading was (73.45 +/- 17.26) N in experimental group, and (104.27 +/- 22.71) N in control group (P <0.01). Histological examination revealed that the defect was repaired by typical bone tissue in experimental group, while only minimal bone formation with fibrous connection in the control group. The tissue-engineering bone with autologous osteogenic ADSCs and scaffol
What this study does not prove
- • This study does not prove SVF is an approved treatment or a replacement for standard care.
