In other words, they recreate lost or damaged tissues, organs and limbs, sometimes slowing, or even stopping aging. Adult stem cells have been identified in many organs and tissues, including brain, bone marrow, peripheral blood, blood vessels, skeletal muscle, skin, teeth, heart, gut, liver, ovarian epithelium, and testis. The liver can regenerate itself up to a point, but once cirrhosis (liver damage in which scar tissue replaces normal liver tissue) has set in, the damage to the liver is irreversible and symptoms are more severe. The process stops, for reasons that are unknown, when the liver volume is within 5 to 10% of its initial value. This regenerative capacity can be enhanced by exogenously supplied plant hormones in vitro , wherein the balance between auxin and cytokinin determines the developmental fate of regenerating organs. Lizards, salamanders, crabs and starfish can all regenerate lost appendages. The Greeks considered the liver to be the home of all human emotions. The investigation of these regenerative processes can provide essential information for understanding the underlining mechanisms of regeneration, for controlling the regenerative processes, and for enhancing the restoration of impaired tissues and organs. Before that can happen, researchers must understand the signals that control regeneration. The complexity of the signaling pathways initiating and terminating this process have provided paradigms for regenerative medicine. How do they regenerate a specific organ and how does it integrate and function properly? By performing an RNAi screen of the planarian pharynx, Sánchez Alvarado and his lab were able to identify genes required for different steps in these complex processes. It functions as the means by which our bodies stay alive and continue forging on. Start studying Tissues (Chapter 4). In a particularly preferred embodiment, erythropoietin (EPO) or a derivative, analogue or parts thereof administered. We evaluated liver regeneration by liver-volume determinations with serial computed tomography scans in four recipients (aged 9 months to 12 years) and their donors (all fathers of the recipients) after living-related liver transplantation. A single organ donor can provide a liver, two kidneys, intestine, pancreas, heart, two lungs that can potentially save the lives of nine others who are suffering from failure of their own organs.
