Background: Biochemical and biophysical factors jointly regulate the cellular dynamics in many physiological processes. It is therefore imperative to include multiplexed microenvironment cues when employing in vitro cell-based assays to model physiological processes. Methods: To meet this need. we have developed a modular platform of 3D cell culture. https://allfixelectricales.shop/product-category/spray-arm-retaining-cap/
