Bright pink gelatiniform liquid with mass ratio of sodium alginate and gelatin of 2:3 was prepared. Rabbit osteoblasts at 5×109/L were mixed with CaCl2 solution to form fruit jelly-shaped sodium alginate-gelatin/osteoblast gel.

Bright pink gelatiniform liquid with mass ratio of sodium alginate and gelatin at ratio of 2:3 was prepared. Rabbit osteoblasts with final concentration of 5×109/L were mixed with CaCl2 solution to form fruit jelly-shaped sodium alginate-gelatin/osteoblast gel. Critical-sized calvarial defects were created in diameter of 1.5 cm in 12 rabbits. After 1 week, cell/scaffold complex (0.5 mL) was implanted to repair the bone defect in the experimental group. There was no treatment in the control group.

METHODS: Titanium nails (1.5 mm in diameter) were separately inserted on two sides of left premaxillary suture in rabbits. A self-made distraction device was used. Gelatum-like substance [V(subscript platelet-rich plasma):V=9:1] was injected into the left premaxillary suture of experimental group rabbits immediately prior to distraction.
