AmnionChorionMembran

The AmnionChorionMembran refers collectively to the amniotic and chorionic membranes that envelop the developing embryo within the uterus. These fetal membranes are formed from trophoblastic and embryonic tissues and play a crucial role in the early stages of mammalian pregnancy. The amniotic membrane, or amnion, derives from the extraembryonic ectoderm, while the chorionic membrane, or chorion, originates from the trophoblast and extraembryonic mesoderm. Together, they create a protective fluid-filled cavity known as the amniotic sac that surrounds the embryo and placenta.

The primary functions of the AmnionChorionMembran include shielding the fetus from mechanical injury and infection, maintaining a stable in‑situ environment, and facilitating the exchange of gases, nutrients, and wastes between maternal and fetal circulations. The amniotic fluid within the sac also provides buoyancy, allowing the fetus to move freely, which stimulates musculoskeletal development. In addition, the membranes contain cytokines and growth factors that contribute to immunological tolerance during pregnancy.

Clinically, abnormalities or premature rupture of the AmnionChorionMembran can lead to conditions such as preterm premature rupture of membranes (PPROM), which is a major risk factor for preterm birth and neonatal morbidity. Inflammation of these membranes, known as chorioamnionitis, can also compromise fetal health and trigger labor. Medical interventions, including sterile delivery techniques and prophylactic antibiotics, are employed to manage these complications and reduce adverse outcomes.

Research on the structural and biochemical properties of the amniotic and chorionic membranes has advanced regenerative medicine, where amniotic membrane allografts are used to treat ocular surface disorders and wound healing. Ongoing studies continue to explore the therapeutic potential of membrane-derived stem cells and extracellular matrix components.
