Fig. 3From: Wnt11 plays an important role in the osteogenesis of human mesenchymal stem cells in a PHA/FN/ALG composite scaffold: possible treatment for infected bone defectPHA was modified with FN and ALG and was transplanted into the infected bone defect after loading with Wnt11-modified MSCs. a Gross appearance of PHA. b Schematic illustration of PHA modified with FN and ALG. c Representative shape of the transfected MSCs. d An infected bone defect (1.0 cm long and 0.5 cm in width) was made for implantation. e PHA/FN/ALG with or without Wnt11-modified MSCs were transplanted into the bone defect site.
