Wound Healing Flashcards
Enzyme necessary for replacement of type III collagen with type I collagen in scar formation
+ cofactor
collagenase
zinc is cofactor
Granulation tissue is made up of
type III collagen
capillaries
myofibroblasts
Healing by
primary intention
secondary intention
1˚ intention: approximate edges
2˚ intention: granulation tissue fills in gap, no approximation of edges
Complication of healing by 2˚ intention
myofibroblasts may contract scar
TGF-β function
inhibits inflammation
Fibroblast growth factor also important in
angiogenesis
Dehiscence is
rupture of wound
Hypertrophic scar
excess production of scar tissue
localized
Keloid scar
excess production of scar tissue out of proportion for wound
