When the tissue has been damaged during the inflammatory process or in other ways, but the body itself is still alive, the tissue will either REGENERATE or BE REPAIRED ("organized") BY FIBROUS TISSUE. The relative contribution of regeneration and scarring in tissue repair depends on the ability of the tissue to regenerate and the extent of the injury. However, mechanisms controlling endometrial repair and regeneration are yet to be fully elucidated.

Musculoskeletal regeneration researchers in the Center for Regenerative Medicine study musculoskeletal tissue injury and repair using molecular, cellular, tissue, organ and whole body-level approaches, including molecular profiling, histology, imaging and biomechanics. The primary goal in regenerative medicine is to facilitate the replacement of injured, diseased or aged tissues with fully functional counterparts, thus extending the healthy life expectancy of our aging population. However, some minor regeneration may occur due to stem cells found in the blood that occasionally enter cardiac tissue. The everchanging knowledge of cell biology still remains largely obscure; however, we can take into account that an indissoluble link between cell apoptosis and tissue regeneration do exist, and it has been consistently confirmed in the last years. Regeneration is a critical biological process that allows preserving tissue function in multi-cellular organisms. This reinvigorates clinical and research efforts directed at replacing or regenerating larger volumes of muscle tissue. of generating a scar or less functional tissue of different form and/or composition than the original is termed repair. Replacement of lost parenchymal cells by division of adjacent surviving parenchymal cells (regeneration) can also restore injured tissue to normal.

The main aim of wound healing is to prevent or limit further damage, to clean and seal the wound against infection, to restore tissue strength, and, if possible, tissue function.

In this proposal, we will examine the skeletal regenerative potential of autologous and allogeneic placental stem cells. Fibrosis- repair by dense fibrous tissue (scarring) Tissue Injury sets a series of events into motion Capillaries become extremely permeable- fluids rich in clotting proteins are allowed to seep into the injured area. The restorative methodology for regeneration of cartilage purposes rapid cartilage repair. Factors related to periodontal regeneration. Restoring the function of injured orthopedic soft tissues to their native state. Regeneration with regression of scar tissue and functional recovery can furthermore be optimized with fat grafting.
