Fig. 2From: Three-dimensional printed PLA scaffold and human gingival stem cell-derived extracellular vesicles: a new tool for bone defect repairMicrocomputed tomography three-dimensional rendering and evaluation of porosity, pore size, and wall thickness at different degradation time point. Scaffolds with a design A, b design B, c design C, d design D, and e design E at T0, T14, and T28. mCT values at T0 for porosity, trabecular thickness (TT), and trabecular separation (TS)Back to article page
