Osteosarcoma, a malignant bone tumor that occurs in adolescents, proliferates and is prone to pulmonary metastasis. Osteosarcoma is characterized by high genotypic heterogeneity, making it difficult to identify reliable anti-osteosarcoma targets. The genotype of osteosarcoma may be highly dynamic, but its high dependence on energy remains constant.

Osteosarcoma (OS) is the most commonly diagnosed primary malignant bone tumor in children and adolescents. Despite significant advancements in therapeutic strategies against OS over the past few decades, the prognosis for this disease remains poor, largely due to its high invasiveness and challenges associated with its treatment. N6-methyladenosine (m6A) modification is one of the most abundant epigenetic modifications of RNAs, and many studies have highlighted its crucial role in OS.

Cancer cells demonstrate remarkable resilience by adapting to oxidative stress and undergoing metabolic reprogramming, making oxidative stress a critical target for cancer therapy. This study explores, for the first time, the redox-dependent anticancer effects of Polydatin (PD), a glucoside derivative of resveratrol, on the human Osteosarcoma (OS) cells SAOS-2 and U2OS. Using cell-based biochemical assays, we found that cytotoxic doses of PD (100-200 µM) promote ROS production, deplete glutathione (GSH), and elevate levels of both total iron and intracellular malondialdehyde (MDA), which are key markers of ferroptosis.

Spheroids, as three-dimensional (3D) cell aggregates, can be prepared using various methods, including hanging drops, microwells, microfluidics, magnetic manipulation, and bioreactors. However, current spheroid manufacturing techniques face challenges such as complex workflows, the need for specialized personnel, and poor batch reproducibility. In this study, we designed a support-free, 3D-printed microwell chip and developed a compatible low-cell-adhesion process.
