Abstract
There are several pathologies associated with the peritoneum, such as mesothelioma and peritonitis. Moreover, the peritoneum is widely used in ultrafiltration procedures, i.e., peritoneal dialysis, presenting advantages over hemodialysis. On the other hand, ultrafiltration failure may lead to dialysis-induced fibrosis and hypervolemia. Therefore, the pathophysiological study of this tissue is of extreme biomedical importance. Studies investigating the biology of the cells dwelling in the peritoneum wall provide evidence of their plasticity and progenitor features. For instance, both mesothelial and submesothelial cells present characteristics similar to mesenchymal stem cells, including osteogenic and adipogenic differentiation potential, support of extramedullary hematopoiesis, modulation of inflammatory responses, and regulation of tumor progression. Indeed, the participation of each cell type in peritoneal pathological and physiological phenomena is still under debate, especially regarding a possible differentiation pathway connecting these peritoneal cells. The primary aim of this review is to raise this discussion. In order to do so, we will firstly provide an overview of the peritoneum anatomy, histology, and ontology, and finally we will address how a better understanding of peritoneal cell biology may contribute to future cell therapy and tissue engineering approaches.
