peritoneal cell

Endometrial cells in women with endometriosis demonstrate increased expression of splice variants of CD44, and increased adherence to peritoneal cells.

The existence of this interferon, which early in its history was known as immune interferon, was recognized in 1970 when tuberculin-sensitized peritoneal cells were challenged with PPD and resulting supernatants were shown to inhibit growth of vesicular stomatitis virus.

Coelomic metaplasia: This theory is based on the fact that coelomic epithelium is the common ancestor of endometrial and peritoneal cells and hypothesizes that later metaplasia (transformation) from one type of cell to the other is possible, perhaps triggered by inflammation.
