Cell proliferation on the seeding matrices printed with various inks was measured for HDF (a) and for SW-1990 (b) after 24 h of incubation (D1) and after 72 h of incubation (D3) at a density of 4 × 103 cells/96-well for HDF and at a density of 3 × 103 cells/96-well for SW/1990 using the MTT assay. The value was reported as the average of two parallel samples.
