Fig. 6From: Enhanced bone regeneration by low-intensity pulsed ultrasound and lipid microbubbles on PLGA/TCP 3D-printed scaffoldsSEW images of scaffolds and BMSCs cultered 7,14 and 21 days. The pores of the scaffolds were covered, and osteogenesis was obvious in the LIPUS + MB group than in the control group. The numbers of cells in the LIPUS + MB group were higher than in the control groupBack to article page
