Study Notes
-
Stable tissues: quiescent cells, capable of proliferating in response to injury or loss of tissue mass, examples include parenchyma of most solid tissues (liver, kidney, and pancreas), endothelial cells, fibroblasts, and smooth muscle cells.
-
Permanent tissues: non-dividing cells, considered terminally differentiated and non-proliferative in postnatal life, examples include neurons and striated muscle cells (skeletal & heart muscle).
-
Injury to tissues: damage to both parenchymal cells and the stromal framework (extracellular matrix).
-
Tissue repair: starts with the formation of granulation tissue and culminates in the laying down of fibrous tissue.
-
Granulation tissue: pink, soft, granular appearance, composed of new blood vessels, loose extracellular matrix, inflammatory cells, and fibroblasts.
-
Tissue healing: phases of inflammation, granulation tissue formation, and ECM deposition and remodeling.
-
Healing by first intention: clean, uninfected surgical incision, minimal tissue disruption, small scar, minimal wound contraction.
-
Healing by second intention: extensive cell or tissue loss, larger clot, more intense inflammation, abundant granulation tissue, large scar, significant wound contraction by the action of myofibroblasts.
-
Factors delaying wound healing: infections, poor nutrition (protein deficiency, vitamin C deficiency), glucocorticoids (steroids), poor perfusion (arteriosclerosis, diabetes), and foreign bodies.
-
Complications of tissue repair: aberrations of cell growth and ECM production, examples include: fibrosis, keloids, scar contractures, and chronic wounds.
