简介：
Overview
This protocol outlines the use of an Open-Top Organ-Chip designed to establish and mature full-thickness organ-on-chip cultures from primary tissues such as skin, alveolus, airway, and intestine. It allows for the investigation of the human epithelial/mesenchymal and vascular niche interface in vitro.
Key Study Components
Area of Science
