With age, AT undergoes significant remodeling, marked by altered fat distribution, visceral fat expansion, impaired thermogenesis, and chronic low-grade inflammation, which disrupts metabolic and immune homeostasis. Emerging insights from single-cell and spatial transcriptomics highlight the critical roles of adipose progenitors, immune cells, and senescent cells in driving local dysfunction and systemic decline. Through inflammatory and metabolic signaling, dysfunctional AT actively contributes to age-related pathologies.

Although automated generation techniques for 3D ECM-encapsulated organoids have been established, limitations in operational simplicity and time efficiency remain barriers to achieving high throughput. Here, we develop a whole-process 3D ECM-encapsulated organoid-based automated HTS (wp3D-OAHTS) platform, which achieves superior throughput compared to existing reported systems for 3D organoid drug screening. Utilizing this automated platform, we generated more than 10,000 homogeneous 3D organoid domes of neuroendocrine cervical cancer (NECC) and evaluated their drug responses to 2802 compounds in 13 days. This highly efficient and reproducible approach finally enabled the identification of 5 top hits that significantly inhibited NECC organoids <i>in vitro</i> with half-maximal inhibitory concentration (IC<sub>50</sub>) of lower than 10 nM. The representative candidate, Quisinostat 2HCl, demonstrated significantly stronger anti-tumor efficacy than clinically used agents <i>in vivo</i>.
