The methods involve the use of conditioned medium derived from specific cell types, such as human mesenchymal stem cells (hMSCs) or ethically sourced human fibroblasts, to support the self-renewal and pluripotency of hPSCs. The conditioned medium is characterized by a specific composition of growth factors and extracellular matrix components that are essential for maintaining stem cell integrity and preventing spontaneous differentiation. Furthermore, the disclosure describes a novel culture system that utilizes a bioreactor or a tissue culture flask with improved gas exchange and nutrient supply, allowing for efficient and scalable expansion of hPSCs. This approach enables the generation of large quantities of high-quality hPSCs for various applications, including regenerative medicine, drug discovery, and disease modeling. The methods disclosed are cost-effective, reproducible, and overcome the limitations of current hPSC culture techniques, paving the way for the clinical translation of stem cell-based therapies.",{"@graph":14,"@context":72},[15,34,55],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/template/","Template",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/template/general/","General",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/template/united-states-patent-amith-et-al/256775/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/united-states-patent-amith-et-al/256775.png","ImageObject",442,249,{"name":42,"@type":43},"Liam","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-09-20","2026-09-13",true,{"@type":52,"interactionType":53,"userInteractionCount":26},"InteractionCounter",{"@type":54},"ViewAction",{"@type":56,"mainEntity":57},"FAQPage",[58,64,68],{"name":59,"@type":60,"acceptedAnswer":61},"What
