New research suggests that wound fluid induced macrophage clustering shows improved healing.
Tissue damage is repaired by the proliferation of normal cells, tissue stem cell maturation, and scar formation. However, the inflammation associated with tissue damage or injury promotes cell plasticity as part of the tissue repair process. Fibroblasts that are critical for wound healing are mesenchymal cells that are actually derived from myeloid cells such as macrophages. Macrophages are immune cells that are the first line of defense against pathogens. They are also important in wound healing and inflammatory processes.
