Mesothelial cell transplantation

Mesothelial cells are an integral part of the peritoneum and play an important role in maintaining its structural and functional properties. In the recent years a number of studies on mesothelial cells have been performed to evaluate the localization, secretional properties and the ability of regeneration and transdifferentiation of these cells. They are also involved in the repair of the peritoneum damage following surgery or peritonitis. Mesothelial cells produce several cytokines, growth factors and extracellular matrix components, possessing anti-inflammatory and immunomodulatory properties. Because of their plasticity, these cells are able to form a new cell type like fibroblast, endothelial and smooth muscle cell, chondrocyte, osteoblast, adipocyte or neuron. The first step involves mesothelial cell transdifferentiation into progenitor cells with the capacity of further differentiation. In this paper the current knowledge concerning the mesothelial cell differentiation and transplantation has been reviewed. Own mesothelial cells of a patient are used in transplantation. They are sampled, cultured in vitro and then they can be used in the prevention and treatment of post-operative abdominal adhesions, incisional hernias, repair of peritoneal membrane of patients on long-term peritoneal dialysis, the prevention of ischemic myocardial damage, nerve regeneration and genetically modified recombinant protein secretion. Inevitably, more potential applications of transplanted mesothelial cell will be available over the next few years.
