SCAMPI: A scalable and accessible micropatterning platform for reproducible organoid morphogenesis

Micropatterning technologies enable biomimetic organoid generation with controlled in vitro morphogenesis but current approaches lack scalability. Here, we develop a mask-based photopatterning platform to enhance organoid culture reproducibility and scalability on diverse substrate formats. We demonstrate its use in generating architecturally defined neural organoids of varying geometries with reproducible morphogenesis. This technology provide a versatile and low-cost strategy for generating geometrically controlled organoids.
