Fig. 3From: Collagen and fibronectin surface modification of nanoporous anodic alumina and macroporous silicon for endothelial cell culturesCell cytotoxicity. Cytotoxicity observed after D1-D7 of HAEC incubation on a regular 12-well plate (blank condition) and in the presence of different substrates functionalized silicon coated with Col or Fn (Flat-Col, PSi-Col, Flat-Fn, and PSi-Fn) and alumina coated with Fn (NAA-Fn). No statistical differences were found in any condition tested. *p < 0.05 versus blank cells conditionBack to article page
