bioGenous^TM Human Kidney Tubular Organoid Kit is a chemically defined cell culture medium for establishing and maintaining of human kidney tubular ductal organoids. This culture medium provides with the essential nutrients needed to self-renewal and self-organization while retaining the ability their original kidney tubular function. Kidney tubular organoids display all hallmarks of the ductal epithelium in terms of architecture, cell type composition, and self-renewal dynamics. The significant expression of biomarkers of kidney tubular stem cells, ductal cells, and progenitor cells indicating the retention of the original kidney tubular properties. Kidney tubular organoids hold great promise for unprecedented studies of human kidney tubular duct regeneration and disease modelling.
