Genome Engineering of Human Urine-Derived Stem Cells to Express Lactoferrin and Deoxyribonuclease.

Urine-derived stem cells (USCs) are adult kidney cells that have been isolated from a urine sample and propagated in tissue culture on gelatin-coated plates. Urine is a practical and completely painless source of cells for gene and cell therapy applications. We have isolated, expanded, and optimized transfection of USCs to develop regenerative therapies based on transposon modification.
