collagen
a family of closely related proteins forming the white fibers of connective tissue, cartilage and bone
basement membrane
delicate structure at the interface between cells and stroma containing collagen, laminin and other matrix components
fibronectin
a family of glycoproteins in with specialized binding sites
proteoglycans
molecules of the extracellular matrix formed by long. unbranched, polysaccharide chains which are covalently bound to a protein core
integrins
a family of cell surface receptors that bind components of the extracellular matrix
cytokine
soluble proteins that bind to specific cell surface receptors, stimulate mitogenic (growth) factors, in order to modulate cell behavior during embryogenesis, normal tissue maintainance, inflammation, immune responses, and wound healing
healing
a restoration of integrity to a injured tissue
contraction
reduction in the size of a wound mediated principally by myofibroblasts
myofibroblast
cell with features of fibroblasts and smooth muscle cells that migrate into a wound 2-3 days after injury; their active contraction decreases the size of a wound
repair
the orderly process by which a wound is eventually replaced by a scar
erosion
a wound in which only the lining epithelium is affected
granulation tissue
formed in the initial response to tissue injury; consists of a richly vascular connective tissue that contains new capillaries, abundant fibroblasts, and inflammatory cells
angiogenesis
pronounced vascular proliferation starting 48-72 hours after injury and lasting several days
regeneration
the renewal of a lost tissue or part in which the missing cells are replaced by identical ones
dehiscence
bursting of a partially-healed wound
