Title Cell-selective encapsulation in hydrogel sheaths via biospecific identification and biochemical cross-linking.
Journal Biomaterials
Abstract Selective encapsulation of a particular cell population from heterogeneous cell populations has potential applications such as studies in cell-to-cell communication, regenerative medicine, and cell therapies. However, there are no versatile methods for realizing this. Here we report a method based on biospecific identification of the target cells through antigen-antibody reaction and subsequent enzymatic hydrogel sheath formation on the cell surfaces by horseradish peroxidase (HRP). Human hepatoma cell line HepG2 cells were selectively encapsulated in alginate-based hydrogel sheath from the mixture with mouse embryo fibroblast-like cell line 10T1/2 fibroblasts using anti-human CD326 antibody conjugated with HRP. The viability of the encapsulated cells was 93%. The cells released at 6 days of the encapsulation by degrading the sheath using alginate lyase grew almost the same as those free from encapsulation. The versatility of the method was confirmed using another antibody, cells, and hydrogel sheath material: Only human vein endothelial cells were encapsulated in gelatin-based hydrogel sheath from the mixture with 10T1/2 fibroblasts using anti-human CD31 antibody conjugated with HRP. The cell-selective encapsulation was also achieved by a system using a primary antibody with a secondary antibody conjugated with HRP.
