This paper reviews how cyclic bleeding in endometriotic lesions triggers a wound-like tissue repair program, focusing on the sequential phases of hemostasis, inflammation, proliferation, and remodeling and the role of platelets as first responders. It synthesizes evidence that repeated tissue injury and repair elicit molecular events that promote lesional progression and eventually lead to lesional fibrosis, highlighting platelet-driven signaling and fibrogenic mechanisms. The chapter’s limitation is that it is a narrative review rather than a primary study, so it does not report a single original dataset or a uniform methodology across cited findings. This paper is centrally about endometriosis — it focuses on the role of platelets in endometriosis pathogenesis and progression toward fibrosis.

Abstract

Endometriosis is often likened to cancer, since endometriotic lesions also exhibit proliferation, apoptosis resistance, invasion, inflammation, angiogenesis, epigenetic aberration, and even cancer-driver mutations. Unlike cancer, however, endometriotic lesions simply do not grow unbridled. In fact, one defining hallmark of endometriotic lesions that sets it apart from cancer cells is cyclic bleeding as in eutopic endometrium. Yet bleeding is a quintessential hallmark of vascular injury and thus tissue injury. Once there is a tissue injury, the evolutionarily conserved tissue repair program would kick in in all organisms. Consequently, endometriotic lesions resemble wounds. Following each bleeding episode, endometriotic lesions go through four, somewhat overlapping, phases of tissue repair: hemostasis, inflammation, proliferation, and remodeling. Among these four phases, platelets are the first responder that participates in tissue repair. It turns out that this repeated tissue injury and repair would elicit several molecular events crucial for lesional progression, eventually leading to lesional fibrosis. Platelets actively participate into these events, promoting the lesional progression and fibrogenesis. In this chapter, the role of platelets in the progression of endometriosis is reviewed, along with therapeutic implication.
