What is the most effective method of increasing growth rate? recruiting G0 cells back into cell cycle
What are labile cells? continuously dividing, stem cells
What are the types of cells that are non-dividing? nerve, skeletal muscle, cardiac
What are quiescent cells? Stable cells
Where do adult stem cells reside? niches
What is granulation tissue? hallmark of healing, fibroblasts, angiogenesis and edema
What is VEGF? vascular endothelial growth factor; stimulates proliferation and motility of endothelial cells
What does Ang 1/Tie2 do? receptor on endothelial cell; promotes maturation of vessels
