Influences of keratinocyte growth factor - mesenchymal stem cells on chronic liver injury in rats.

To study the effects of keratinocyte growth factor (KGF) modified umbilical cord mesenchymal stem cells (MSC) on chronic liver injury in rats, adenovirus carrying human KGF gene (Ad-KGF) was used. Rat liver injury model was established by subcutaneous injection of CCl4 - olive oil solution; 56 male Wistar rats were randomly divided into normal control, model, MSC, KGF, and KGF/MSC groups. Of all three treatments, KGF/MSC had the most obvious therapeutic effects on liver injury, and cell injections did not cause adverse reaction. The experiment provides new data for clinical research of KGF/MSC and possible methods for liver injury treatment.
