Microencapsulation preparation and in vitro culture. Photoencapsulation of alginate microspheres and MSCs into Methacrylated HA (MeHA) hydrogel disks (A); fabricated HA hydrogel disk and fluorescent and bright field microscopic images of MSCs (membrane labeled with red dye) and alginate microspheres (containing FITC-labeled protein) encapsulated in HA gels (B); release of encapsulated BSA-FITC from bare and coated alginate microspheres over 7 days in PBS (C), scale bar = 50 μm.
