Fig. 11From: Accelular nanofibrous bilayer scaffold intrapenetrated with polydopamine network and implemented into a full-thickness wound of a white-pig model affects inflammation and healing processLive-Dead assay of murine fibroblast cell line 3T3-A31 seeded on porous foams on the 14th experimental day. Collagen foam is Coll; collagen/chitosan foam is Coll/Chit, and collagen/oxidized cellulose foam is Coll/CaOC. The mark ‘PDA’ represents an additional polydopamine coating on porous foams.
