Endometriosis is a complex and heterogeneous disorder of unknown aetiology. This benign disease possesses special biological behaviours that mimic those of malignant tumours. A pro-endometriotic niche established by an existing lesion is a supportive micro-environment for the progression of endometriosis. After the accumulation of cells by an existing lesion, these components display distinct characteristics that impair immune surveillance. Subsequent retrograde menstruation of endometrial stromal cells into the pro-endometriotic niche facilitates endometriotic progression from early initiation to an advanced lesion. This study aimed to highlight the innovative role of the pro-endometriotic niche in endometriosis, and to provide valuable treatment targets for endometriosis.
