The human gut-on-a-chip has demonstrated invivo-relevant cellular fidelity and physiological functions of Caco-2 intestinal epithelium compared to its static cultures. However, transcriptomic dynamics that controls the morphogenic and mechanodynamic perturbation of Caco-2 epithelium in a microphysiological culture remain elusive. Single-cell transcriptomic analysis revealed that a gut-on-a-chip culture drives three clusters that illustrate distinct gene expressions and theirspatial representation in three-dimensional (3D) epithelial layers. A pseudotemporal trajectory analysis elucidated the evolutionary transition from a homogeneous ancestral genotype in Transwell cultures into heterogeneous transcriptomes in gut-on-a-chip cultures, verified in cell cycle perturbation, cytodifferentiation, and intestinal functions in digestion, transport, and drug metabolism. Furthermore, the inversed transcriptomic signature of oncogenes and tumor-suppressor genes of Caco-2 cells confirmed that gut-on-a-chip cultures induce post-mitotic reprogramming of cancer-associated genes. Our study suggests that aphysiological gut-on-a-chip culture induces the transcriptomic perturbation of Caco-2 epithelium to elicit invivo-relevant morphogenesis and restoration of normal physiological functions.
