Fig. 12From: Accelular nanofibrous bilayer scaffold intrapenetrated with polydopamine network and implemented into a full-thickness wound of a white-pig model affects inflammation and healing processThe cell distribution on the scaffolds—day 14. 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. Cytoplasmic membranes (DiOC6[3], green signal), cell nuclei (propidium iodide, red signal). Scale bar 50 µm, objective 20 × Back to article page
