Abstract (original English)
This study aimed to assess the efficacy of hepatocyte growth factor (HGF)-transfected adipose-derived mesenchymal stem cell (ADSC) transplantation in the injured vocal folds (VFs) of canines. A lentiviral vector encoding HGF was successfully produced via Gateway cloning, which was used to infect ADSCs. Four weeks after transoral laser microsurgery (type II) with CO 2 laser, the beagles of each group were injected with HGF-transfected ADSCs or uninfected ADSCs into VFs. The results showed that the retention of HGF-transfected ADSCs in the VFs persisted about three months post-injection. The VFs in the HGF-transfected ADSCs group exhibited a closer-to-normal structure with less collagen deposition and higher amounts of hyaluronic acid (HA) in the third month. The short microvilli in the HGF-transfected ADSCs group showed a dense and uniform distribution. These results revealed that HGF-transfected ADSC is a potential treatment option for injured VFs.
What this study does not prove
- • This study does not prove SVF is an approved treatment or a replacement for standard care.
- • This is preclinical work; animal or laboratory results cannot be applied to humans.
Evidence level
