A microphysiologic human cervical model recapitulates microbial, immune, and pathogenic properties of sexually transmitted infections.

Sexually transmitted infections (STIs) of the cervicovaginal mucosa are among the most common global infections. Current monolayer cell culture and animal models fail to reproduce the multilevel complexity required to investigate host-microbiota-pathogen relationships simultaneously and/or with sufficient physiological relevance. To address this limitation, we have developed a microphysiologic system (MPS) that models human cervical tissue and its microbiota and is susceptible to infection by two prominent genital pathogens, Chlamydia trachomatis and Neisseria gonorrhoeae. Notably, this MPS platform recapitulates essential dynamic, polymicrobial, immune, and pathogenic features of chlamydial and gonococcal infections as they occur in humans. The low-cost MPS device requires no specialized equipment or specific expertise and was experimentally validated across multiple nonengineering, remotely located laboratories, demonstrating its transferability and reproducibility. The platform provides a tool for research into genital infections in a system that closely mimics the cervical epithelium, an important advance over existing models.
