Objective: To highlight the in vivo protein markers in human peritoneal mesothelial cells according to their anatomical distribution and their interest in theories of peritoneal repair.
Design: Clinical laboratory study.
Setting: University Hospital, France.
Patients: Sampling of mesothelial cells during 8 laparotomies by impression smears.
Main Outcome Measures: Immunochemical semiquantitative measures of proteins.
Results: There were uniform ratios of protein markers among the whole peritoneal mesothelial cell population, whatever their anatomical origin (liver, stomach, omentum, small bowel, and abdominal wall).
Conclusion: This is consistent with the surrounding uninjured mesothelial cells or the exfoliated mesothelial cells, or both, having a role in postoperative peritoneal mesothelial repair.

Pleural mesothelioma (PM) is a rare and highly aggressive malignancy originating from the pleural lining, with a median overall survival of merely 1 year. This cancer primarily arises from mesothelial cells following exposure to carcinogenic, biopersistent mineral fibers, particularly asbestos. The histological subtypes of mesothelioma are epithelioid (approximately 60%), sarcomatoid (20%), and biphasic (20%), exhibiting epithelioid and sarcomatoid characteristics.

Background: Impairment of the visceral pleura following thoracic surgery often leads to air leaks and intrathoracic adhesions. For preventing such complications, mesothelial cell proliferation at the pleural defects can be effective. To develop new materials for pleural defects restoration, we constructed a hybrid artificial pleural tissue (H-APLT) combining polyglycolic acid (PGA) nanofiber sheets with a three-dimensional culture of mesothelial cells and fibroblasts and evaluated its therapeutic efficacy in a rat pleural defect model.

Embryonic hematopoietic cells develop in the fetal liver (FL), surrounded by diverse non-hematopoietic stromal cells. However, the spatial organization and cytokine production patterns of the stroma during FL development remain poorly understood. Here, we characterized and mapped the hematopoietic and stromal cell populations at early (E12.

Long-term exposure of the peritoneum to peritoneal dialysate results in pathophysiological changes in the anatomical organization of the peritoneum and progressive development of peritoneal fibrosis. This leads to a decline in peritoneal function and ultrafiltration failure, ultimately necessitating the discontinuation of peritoneal dialysis, severely limiting the potential for long-term maintenance. Additionally, encapsulating peritoneal sclerosis, a serious consequence of peritoneal fibrosis, resulting in patients discontinuing PD and significant mortality.
