Bone regeneration using cell-laden GelMA microspheres. (A) Schematic
illustration for the fabrication of cell-laden GelMA microspheres using a
photo-cross-linking-microfluidic method, and in vitro and in vivo applications
for osteogenesis and bone regeneration in a rabbit model. (B) Alizarin red
staining results of cell-laden GelMA microspheres after (a) 1, (b) 2, (c) 3, and
(d) 4 weeks of culture for in vitro osteogenesis. Scale bar: 100 μm. (C)
Histomorphometric results (%) of new bone (left) and osteoid (right) formation.
