Human Renal Cortical Epithelial Cells (HRCEpC)
Primary Human Renal Cortical Epithelial Cells (HRCEpC) are isolated from the cortex of the human kidney and stain positive for cytokeratin. The renal cortex is the outer portion of the kidney between the renal capsule and the renal medulla. It contains the renal corpuscles, the proximal and distal convoluted tubules, and the cortical collecting ducts.
Important physiological processes like osmoregulation and excretion can be studied with HRCEpC in vitro.
- Our HRCEpC are now also available from HLA-typed donors
Recommended plating density | 10000 - 15000 cells per cm2 |
Passage after thawing | P2 |
Tested markers | Cytokeratin positive |
Guaranteed population doubling | > 15 |
PromoCell provides two types of Renal Epithelial Cells: Human Renal Epithelial Cells (HREpC) and Human Renal Cortical Epithelial Cells (HRCEpC). HREpC are isolated from the adult kidney and stain positive for cytokeratin. They comprise a heterogeneous population of renal epithelial cells. HRCEpC are isolated from the cortex of the kidney and comprise cells from proximal and distal tubuli. They also stain positive for cytokeratin.
Short protocol:
- Trypsinize the cells as usual
- Centrifuge and resuspend in suitable cold freezing medium at a density of 1-4 x 106 cells/ml
- Cool down the cells slowly to -80°C (approx. -1°C per min). We recommend to use "Mr. Frosty" from Nalge or "CoolCell" from Biocision; which both provide gradual and controlled cooling rates when placed in a -80°C freezer overnight.
- Transfer the vials into liquid nitrogen for long-term storage
- Mesenchymal Stem Cells (C-12974/C-12971/C-12977) need Fibronectin-coating when grown in PromoCell MSC Growth Medium XF (C-28019) and when differentiated in MSC Neurogenic (C-28015); Adipogenic (C-28016); or Osteogenic (C-28013) Differentiation Media.
- Human monocyte-derived macrophages (C-12914/C-12916/C-12915/C-12917) must be seeded into Fibronectin-coated culture vessels in combination with PromoCell's M1- and M2-Generation Media XF (C-28055; C-28056).
- For efficient induction of osteoblast mineralization with PromoCell's Osteoblast Mineralization Medium (C-27020); the TC plates should be pre-coated with collagen type I.
- Liquid phase storage provides a consistent temperature of -196°C; a longer holding time and a greater vial capacity but involves the risk of contamination issues.
- Storage in the gas phase is very safe with respect to contaminations but the holding time of the cells is shorter and the vial capacity is reduced.
