Background: Infertility is a special reproductive health defect. For women, congenital uterine malformations, extensive adhesions in the uterine cavity, and hysterectomy are associated with infertility. Uterine transplantation is technically feasible, but its clinical application and development are limited by donor shortages and immune rejection.

Periodontitis is a chronic inflammatory disease that destroys tooth-supporting structures and poses significant public health challenges due to its high prevalence and links to systemic health conditions. Traditional treatments are effective in reducing the inflammatory response and improving the clinical symptoms of periodontitis. However, these methods are challenging to achieve an ideal treatment effect in alveolar bone repair.

We are witnessing an ongoing global biodiversity crisis, and an increasing number of mammalian populations are at risk of decline. Species that have survived severe historic bottlenecks, such as the cheetah (Acinonyx jubatus) exhibit symptoms of inbreeding depression including reproductive and developmental defects. Although it has long been suggested that such defects stem from an accumulation of weakly deleterious mutations, the implications of such mutations leading to pseudogenization has not been assessed.

Adult hippocampal neurogenesis is linked to memory formation In the adult brain, with new neurons in the hippocampus exhibiting greater plasticity during their immature stages compared to mature neurons. Abnormal adult hippocampal neurogenesis is closely associated with cognitive impairment in central nervous system diseases. Targeting and regulating adult hippocampal neurogenesis have been shown to improve cognitive deficits.

Traditional polymer systems often rely on toxic initiators or catalysts for cross-linking, posing significant safety risks. For bone tissue engineering, another issue is that the scaffolds often take a longer time to degrade, inconsistent with bone formation pace. Here, we developed an enzyme-responsive biodegradable poly(propylene fumarate) (PPF) and polycaprolactone (PCL) polyphosphoester (PPE) dendrimer cross-linked utilizing click chemistry (EnzDeg-click-PFCLPE scaffold) for enhanced biocompatibility and degradation.
