## Abstract

Injuries and diseases of the peripheral nervous system (PNS) often result in irreversible functional deficits. Current therapeutic approaches demonstrate limited efficacy, which has driven the development of regenerative medicine strategies. This review systematizes contemporary gene and cell therapy approaches aimed at PNS repair and regeneration. Key neurotrophic factors (NGF, BDNF, GDNF, VEGF, etc.) and the molecular mechanisms underlying their regenerative effects are discussed. Gene delivery strategies employing viral and plasmid vectors are analyzed, along with the therapeutic application of various cell populations, including Schwann cells, mesenchymal stromal cells, and derivatives of induced pluripotent stem cells. Particular attention is given to combined gene–cell-based approaches, which enable localized and sustained expression of therapeutic molecules. The integration of advances in genetic engineering, cell biology, and tissue engineering is shaping a new treatment paradigm focused on pathogenetic restoration of nerve tissue. These promising strategies pave the way toward achieving complete functional regeneration following PNS injuries.
