  • Preparation of rat uterine decellularized scaffold and extracellular matrix hydrogel

    The chemical extraction method was used to prepare the rat uterine decellularized scaffolds, and to investigate the feasibility of preparing the extracellular matrix (ECM) hydrogel. The rat uterus were collected and extracted by 1%sodium dodecyl sulfate (SDS), 3% TritonX-100 and 4% sodium deoxycholate (SDC) in sequence. Scanning electron microscopy, histochemical staining and immunohistochemistry was used to assess the degree of decellularization of rat uterine scaffold. The prepared decellularized scaffold was digested with pepsin to obtain a uterine ECM hydrogel, and the protein content of ECM was determined by specific ELISA kit. Meanwhile, the mechanical characteristic of ECM hydrogel was measured. The results showed that the chemical extraction method can effectively remove the cells effectively in the rat uterine decellularized scaffold, with the ECM composition preserved completely. ECM hydrogel contains a large amount of ECM protein and shows a good stability, which provides a suitable supporting material for the reconstruction of endometrium in vitro.
