In tissue engineering, decellularized scaffolds have been proved to have remarkable capacity to promote regeneration in various organs such as kidney, heart, lung, and liver. Marrying the field of cryobiology and reproductive medicine resulted in considerable progress and breakthroughs, which led to the emergence of ovarian tissue cryopreservation and transplantation as a promising option for fertility preservation. Here we describe an innovative application of decellularized tissue scaffolds as a regenerative platform for reconstruction of ovarian grafts for auto-transplantation.

The reconstruction of large-sized soft tissue defects remains a substantial clinical challenge, with adipose tissue engineering emerging as a promising solution. The acellular dermal matrix (ADM), known for its intricate spatial arrangement and active cytokine involvement, is widely employed as a scaffold in soft tissue engineering. Since ADM shares high similarity with decellularized adipose matrix, it holds potential as a substitute for adipose tissue.

Organoid technology, as an innovative approach in biomedicine, exhibits promising prospects in disease modeling, pharmaceutical screening, regenerative medicine, and oncology research. However, the use of tumor-derived Matrigel as the primary method for culturing organoids has significantly impeded the clinical translation of organoid technology due to concerns about potential risks, batch-to-batch instability, and high costs. To address these challenges, this study innovatively introduced a photo-crosslinkable hydrogel made from a porcine small intestinal submucosa decellularized matrix (SIS), fish collagen (FC), and methacrylate gelatin (GelMA).

Corneal substitutes with structural and compositional characteristics resembling those of natural corneas have attracted considerable attention. However, biomimicking the complex hierarchical organization of corneal stroma is challenging. In this study, humanized corneal stroma-like adhesive patches (HCSPs) are prepared through a multi-step process.

Currently, there are no therapies that prevent the negative myocardial remodeling process that occurs after a heart attack. Injectable hydrogels are a treatment option because they may replace the damaged extracellular matrix and, in addition, can be administered minimally invasively. Reactive oxygen species generated by ischemia-reperfusion damage can limit the therapeutic efficacy of injectable hydrogels.
