Confocal laser scanning microscopy analysis. Left panels: Human gingival mesenchymal stem cells (hGMSCs) anti-ANA positive nuclei in a 3D-PLA + hGMSCs, b 3D-PLA + extracellular vesicles (EVs) + hGMSCs, and c 3D-PLA + polyethyleneimine (PEI)-EVs + hGMSCs (green fluorescent). Middle panels: Confocal contrast image of 3D-PLA (gray) grafted in mice calvaria after 6 weeks of implantation. Right panels: Merged images of the two abovementioned channels.
