Gelatin Microspheres Loaded with Wharton’s Jelly Mesenchymal Stem Cells Promote Acute Full-Thickness Skin Wound Healing and Regeneration in Mice

3D gelatin microspheres (GM) had strong biocompatibility, comparing with two-dimensional adherent culturing, GM loading increased the cell viability, and proliferation ability of Wharton’s jelly MSCs.
