This study investigated whether the Intercoat® cellular barrier could prevent the proliferation, adhesion, and invasion of primary endometriosis cells in vitro. Researchers cultured these cells with or without the barrier agent and observed that the presence of a thin layer significantly inhibited cell adhesion, which is necessary for subsequent growth. Furthermore, when a drop of the substance was applied directly to the culture medium, endometriosis cells failed to adhere and grow in the immediate vicinity of the barrier. The authors conclude that such barriers may physically block floating endometrial cells from attaching to peritoneal defects, potentially reducing disease relapse after surgery. This paper is centrally about endometriosis — specifically testing an adhesion barrier to prevent cell implantation and recurrence of the disease.

Background

In the pathogenesis of endometriosis adhesions play a major role. Applying adhesion barrier on the peritoneal wound that might act as a seeding ground could also prevent endometrial cells to adhere, invade and grow and thus cause a relapse of the disease.

Methods

Cultured endometriosis cells were seeded on the media with or without the Intercoat® cellular barrier. Following six days of culture, all cells were collected and counted to determine the total number of live. Additionally a drop of Intercoat® was placed in the middle of a well in another experiment.

Results

After seeding the cells in the well it could be shown that adhesion of cells, which is mandatory for growth and proliferation, was inhibited after application of a thin Intercoat® layer. Moreover when putting a single drop of the substance in the well it could be shown that no cells adhered and grew in the area around and in the drop while growth was unremarkable further away.

Discussion

Our hypothesis was, that peritoneal defects after surgical intervention and tissue remodeling are a seeding ground for floating endometrial cells in the peritoneal fluid. By preventing direct contact with the defect adhesions of these cells could be inhibited and thus relapse rates for endometriosis could be lowered. It is the first time, that a direct interaction between a barrier agent and cells could be shown, especially as growth was inhibited in an area around the Intercoat drop.
