|
collagen
|
a family of closely related proteins forming the white fibers of CT, cartilage, and bone
|
|
|
basement membrane
|
delicate structure at the interface b/n cells and stroma containing collagen, laminin, and other matrix components
|
|
|
fibronectin
|
family of glycoproteins in which specialized binding sites allow binding to a variety of structures
|
|
|
proteoglycans
|
molecules of extracellular matrix formed by long, unbranched, polysaccaride chains which are covalently bound to a protein core
|
|
|
integrins
|
family of cell surface receptors that bind components of 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 maintenance, inflammation, immune reponses, and wound healing
|
|
|
healing
|
a restoration of integrity to an injured tissue
|
|
|
contraction
|
a reduction in 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
|
orderly process by which a wound is eventually replaced by a scar
|
|
|
erosion
|
wound in which only the lining epithelium is affected
|
|
|
granulation tissue
|
formed in the initial response to tissue injury, consists of a richly vascular CT that contains new capillaries, abundant fibroblasts, and imflammatory cells
|
|
|
angiogenesis
|
pronounced vascular proliferation starting 48-72 hours after injury and lasting several days
|
|
|
regeneration
|
renewal of a lost tissue or part in which the missing cells are replaced by identical ones
|
|
|
dehiscence
|
bursting of a partially-healed wound
|
