Fig. 1

(A) Schematic of the chemical structures and proposed in vitro or in vivo degradation mechanism of BAMs. (B) Potential mechanism of degradation fragments mediated bioenergetic effects for enhanced bone regeneration. (C) Representative scanning electron microscopy image (left), as well as longitudinal section (middle) and pseudo-color 3D (right) micro–computed tomography images, showing the uniform and interconnected pore structure of a typical BAM scaffold, with pore diameters ranging from 150 to 250 μm. α-KG, α-ketoglutarate; NADH, reduced form of NAD+.
