This is a polarized epithelial cell line which retains many differentiated characteristics of the terminal IMCD including inhibition of apical to basal sodium flux by amiloride and by atrial natriuretic peptide (ANP).
The cells possess an amiloride sensitive sodium channel as determined by Western blot analysis, and accumulate the major organic osmolytes (inositol, sorbitol, betaine and glycerophosphorylcholine) in response to hypertonic stress.
The cells secrete endothelin and form tubules and tight junctions.
mIMCD-3 cells are responsive to Hepatocyte Growth Factor (HGF), and are readily adaptable to growth in hypertonic medium supplemented with NaCl and urea up to 910 mosmol/kg H20. These extreme osmotic conditions exist in the renal medulla in vivo, but are known to be lethal to most other cells.
