Graphical AbstractScheme for cultured meat preparation (A) Gelatin–soymilk solution is prepared and then put on the PDMS mold to prepare a GS scaffold with parallel microchannels. (B) The C2C12 myoblasts and 3T3-L1 pre-adipocytes are seeded on the GS scaffold to prepare adipocyte-topped muscle-like layers and adipose-like layers. (C) The two layers are then stacked layer by layer to assemble into cultured meat containing fat.
