Method description
Gelatin-methacryloyl-aminoethyl-methacrylate (gel-MA-AEMA)-, and gelatin-methacryloyl-norbornene (gel-MA-NB)-based biomaterial inks fabricated into 3D hydrogels (“villi only” versus “crypts and villi”) with digital light processing and co-cultured Caco-2/HT29-MTX cells.
Lab equipment
- - Printer (CellInk LumenX+)
- - Standard cell culture equipment
Method status
- Published in peer reviewed journal
Pros, cons & Future potential
Advantages
- - Intestinal epithelial cells have more enhanced functional barrier formation and enterocyte differentiation.
- - Biocompatibility of the material.
Modifications
- - Inclusion of primary cells such as gut organoids.
- - Addition of the 3D structures in millifluidics system, adding relevant shear stress to the cells.
