Cell Membrane-Coated Electrospun Fibers Enhance Keratinocyte Growth through Cell-Type Specific Interactions

Although cell membrane-coated fiber scaffolds can be useful for regenerative medicine by presenting both cell surface antigens and topographical cues, it remains unknown whether changes in cellular behavior on cell membrane-coated scaffolds are due to specific cell-cell interactions. In this work, the effects of scaffold fiber diameters and surface charges on the cell membrane coating efficiency were explored. Furthermore, fibroblast membrane-coated scaffolds improved the growth of human keratinocytes as compared to red blood cell membrane-coated and plain scaffolds. These results suggest the biofunctionality of cell membrane-coated scaffolds and the specific cell-cell interactions that are preserved to modulate cellular response.
