The molecular functions of polycystins remain uncertain, and therapeutics remain limited for millions of patients. One major roadblock has been the scarcity of assays that re-create PKD-specific cystogenesis in vitro, to complement mouse models. Summary: Over the past decade, a human organoid model of PKD has emerged that promises to bridge this gap. Human kidney organoids derived from PKD1\u2212\/\u2212 or PKD2\u2212\/\u2212 pluripotent stem cells recapitulate the pathognomonic cystic phenotype in a PKD-specific manner. Here we review important achievements, current limitations, and future strategies, with a focus on translational \u201cbench to bedside\u201d potential of PKD organoids as drug development tools. Key Messages: Human PKD organoids reveal that PKD cystogenesis is a cell intrinsic process that can be re-created in vitro. These systems have revealed unexpected mechanisms for PKD cystogenesis and have been utilized to blueprint new therapeutic strategies, but their potential is not yet fully realized. The complexity and cost of organoids remain significant barriers to entry, and dedicated technology development is required to improve their physiological relevance.<\/jats:p>","DOI":"10.1159\/000553552","type":"journal-article","created":{"date-parts":[[2026,7,21]],"date-time":"2026-07-21T16:01:11Z","timestamp":1784649671000},"page":"1-9","source":"Crossref","is-referenced-by-count":0,"title":["Human
