Hydrogel Embedding of Mesenchymal Stem Cells Supports Extracellular Vesicle Production

open access: yesBiotechnology and Bioengineering, EarlyView.
This study investigates the effects of 3D culture conditions on extracellular vesicle (EV) production by mesenchymal stem cells (MSCs) in a gelatin‐based hydrogel matrix (GelMA). The EVs from both conditions were found to have similar morphological, molecular, and functional properties, but 3D cultures produced more total EVs per volume.
