The linear excisional wound: an improved model for human ex vivo wound epithelialization studies


Background/purpose: Wound healing is a complex process that involves multiple intercellular and intracellular processes and extracellular interactions. Explanted human skin has been used as a model for the re-epithelialization phase of human wound healing. The currently used standard technique uses a circular punch biopsy tool to make the initial wound. Despite its wide use, the geometry of round wounds makes it difficult to measure them reliably.


Methods: Our group has designed a linear wounding tool, and compared the variability in ex vivo human linear and circular wounds.


Results: An ...
