Defects in androgen production or in response to androgen signaling can lead to various congenital penile anomalies in both mice and humans. Due to lack of a high-throughput screening system, identification of crucial regulators of GT sexual differentiation has been slow. To overcome this research barrier, we isolated embryonic GT mesenchymal (GTme) cells to model genitalia growth and differentiation in vitro. Using either a mechanical or fluorescence-activated cell sorting\u2013assisted purification method, GTme cells were isolated and assayed for their proliferation using a microscopy and image analysis system, on a single cell level over time. Male and female GTme cells inherently exhibit different cellular dynamics, consistent with their in-vivo behaviors. This system allows for the rapid quantitative analyses of numerous drug treatments, and enables the discovery of potential genetic modulators of GT morphogenesis on a large scale. Using this system, we completed a 438-compound library screen and identified 82 kinase inhibitor hits. In mice, in-utero exposure to one such candidate kinase inhibitor, Cediranib, resulted in embryos with severe genitalia defects, especially in males. Gene silencing by RNAi was optimized in this system, laying the foundation for future larger-scale genetic screenings. These findings demonstrate the power of this novel high-throughput system to rapidly and successfully identify modulators of genitalia growth and differentiation, expanding the toolbox for the study of functional genomics and environmental factors.<\/jats:p>","DOI":"10.1093\/pnasnexus\/pgac300","type":"journal-article","created":{"date-parts":[[2022,12,28]],"date-time":"2022-12-28T23:02:05Z","timestamp":1672268525000},"source":"Crossref","is-referenced-by-count":2,"title":["Development of an in-vitro high-throughput screening system to identify modulators of genitalia development"],"prefix":"10.1093","volume":"2","author":[{"given":"Yan","family":"Yin","sequence":"first","affiliation":[{"name":"Division of Dermatology, Department of Medicine, Washington University School of Medicine , 660 S.
