(A) Typical representation of the chronic wound bed microenvironment. (B) Key features of the chronic wound bed-capillary interface. From a bioengineering standpoint, the microenvironment can be represented by a two-compartment system, where the upper compartment consists of the “infected wound bed” with host cells, matrix and microbial biofilms and the lower compartment represents the capillary interface (endothelial cells) with immune components. (C) A simplified representation of key interactions between chronic wound biofilms and other key components of the chronic wound microenvironment, which can be suitably dissected on human-relevant bioengineered platform.
