Excretory System Epithelial Cells: Bladder and Renal Epithelial Cells

The excretory system processes the body’s waste and excretes waste as urine. The two kidneys filter waste products from the blood, creating urine. The urine is then passed from the kidney to ureters, finally reaching the bladder from where urine is excreted. Renal cancer and bladder cancer are both initiated in kidney (renal) and bladder epithelial cells, respectively.

Lifeline® provides both bladder and renal epithelial cells for your research needs.

  • Bladder epithelial cell types include bladder dome epithelial and apex bladder epithelial cells, isolated from different areas of the bladder and optimized for growth in UroLife™
  • Renal epithelial cells offered by Lifeline® and optimized for growth in RenaLife™ medium include: renal medullary epithelial cells, renal proximal tubule epithelial cells, and renal cortical epithelial cells.

Both renal and bladder epithelial cells can be used for multiple research applications. Studies using these cells for such applications are listed below.

Studies Using Lifeline® Bladder and Renal Cells for Research Applications

Studies that investigated the anti-tumor activity of a new peptide or a new combination of chemotherapeutic agents in cancer cell lines versus Lifeline® normal human bladder cells:
