Fetal progenitor cells for treatment of chronic limb ischemia.

Objectives: This study investigated the therapeutic potential of fetal progenitor cells (FPCs) in the treatment of chronic non-healing wounds and ulcers associated with chronic limb ischemia (CLI). The research aimed to elucidate the mechanism of action of FPCs and evaluate their efficacy and safety in CLI patients.

Methods: The researchers isolated FPCs from aborted human fetal liver, brain, and skin tissues and thoroughly characterized them.
