Abstract
The uterus is considered to be a unique wound-healing model and distinguished by the repeated shedding of the endometrium and self-traceless regeneration. Common curettage, cesarean section, and other operations often cause endometrial and myometrial defects and obstetric and gynecological complications, leading to a high demand for uterine repair or partial replacement. However, the structure and function of the uterus are complicated. Functional uterine tissue engineering requires highly specialized biomaterials with a natural extracellular microenvironment. Currently, no biomaterial can fully simulate the structural and biomechanical properties of the uterus. Many efforts have been made to develop highly functional materials and tissue structures that may provide uterine tissue engineering constructs for reducing obstetric and gynecological complications. Continuous efforts will likely facilitate the development of scalable cells and biomaterial technologies for clinical use. This review summarizes the recent applications of biomaterials and tissue engineering in rebuilding a portion of or the entire uterus.
