Mesenchymal Stem Cells in Oriented PLGA/ACECM Composite Scaffolds Enhance Structure-Specific Regeneration of Hyaline Cartilage in a Rabbit Model

Figure 1

Schematic illustration of the experimental design. Autologous bone marrow-derived MSCs were loaded into oriented PLGA/ACECM composite scaffolds and implanted to regenerate cartilage defects in a rabbit model. The study involved three groups: a cell-loaded scaffold group, a scaffold-alone group, and an untreated (control) group.
