Lonza’s Human Renal Epithelial (HRE) cells are an expansion of HNK (human neonatal kidney) cells. The kidneys are homogenized and the mixed population of cells are cultured in Lonza REGM™ Renal Epithelial Cell Growth Medium for one passage prior to cryopreservation. These cells are isolated from the whole kidney and will be comprised of any epithelial cells from the kidney including renal proximal tubule epithelial cells, distal tubule epithelial cells and glomerular epithelial cells.
