Mesenchymal stem cells
Development of mesenchymal stem cells (MSCs) is a new technology for treatment of various degenerative diseases in cats. Stem cells are multipotent cells that can differentiate into a variety of cell types and have been generated from feline cardiac cells, neural cells and renal cells.
Intrarenal injection of mesenchymal cells did not induce immediate or long-term adverse effects and two cats with renal disease that received stem cells experienced modest improvement in glomerular filtration rate and a mild decrease in serum creatinine concentration.
Despite the possible benefits of intrarenal MSC injections for CKD cats, the number of sedations and interventions required to implement this approach would likely preclude widespread clinical application.
