Abstract

Abstract: Designer self‐assembling peptides form the entangled nanofiber networks in hydrogels by ionic‐complementary self‐assembly. This type of hydrogel has realistic biological and physiochemical properties to serve as biomimetic extracellular matrix (ECM) for biomedical applications. The advantages and benefits are distinct from natural hydrogels and other synthetic or semisynthetic hydrogels. Designer peptides provide diverse alternatives of main building blocks to form various functional nanostructures. The entangled nanofiber networks permit essential compositional complexity and heterogeneity of engineering cell microenvironments in comparison with other hydrogels, which may reconstruct the tumor microenvironments (TMEs) in 3D cell cultures and tissue‐specific modeling in vitro. Either ovarian cancer progression or recurrence and relapse are involved in the multifaceted TMEs in addition to mesothelial cells, fibroblasts, endothelial cells, pericytes, immune cells, adipocytes, and the ECM. Based on the progress in common hydrogel products, this work focuses on the diverse designer self‐assembling peptide hydrogels for instructive cell constructs in tissue‐specific modeling and the precise oncology remodeling for ovarian cancer, which are issued by several research aspects in a 3D context. The advantages and significance of designer peptide hydrogels are discussed, and some common approaches and coming challenges are also addressed in current complex tumor diseases. Abstract : Designer self‐assembling peptides are favorable building blocks compared to other hydrogels, which mimic 3D extracellular matrix at the nanometer scale by bioengineering nanotechnology. In 3D cell cultures, various cell constructs are fabricated by this kind of hydrogels in tissue engineering and regenerative medicine. Herein, the precise oncology remodeling is addressed by several main aspects involved in ovarian cancer.
