Wound Repair and Regeneration jy to tissue fibroblasts with disorganized ECM Scar Non f nctional tissue Lung-functional tissue Kidney Heart Skin Liver Spleen Classic Stages of Wound Repair • Inflammation – until 48 hrs. As nouns the difference between restoration and regeneration is that restoration is the process of bringing an object back to its original state; the process of restoring something while regeneration is rebuilding or restructuring; large scale repair or renewal. By definition, regeneration is the proliferation of cells and tissues to replace lost tissues whereas repair is a fibroproliferative response in a combination of regeneratation and scar formation. • Injury to cells and tissues sets in motion a series of events that contain the damage and initiate the healing process. In this Division 2 video I just wanted to talk about some of the healing stats I have been testing. Tissue Renewal, Regeneration, and Repair 2.
