Abstract

Mesenchymal stem cells (MSCs) are known for their ability to repair liver damage. However, their therapeutic potential still needs to be enhanced. In the present study, we produced genome-edited MSCs that secrete interleukin 10 (IL-10) and evaluated their therapeutic potential in a liver fibrosis model. Multiple copies of the IL-10 gene were inserted into a safe harbor genomic locus in amniotic mesenchymal stem cells (AMMs) using transcription activator-like effector nucleases (TALENs). The IL-10 gene-edited AMMs (AMM/I) were characterized by reverse transcription PCR (RT-PCR), quantitative RT-PCR (qRT-PCR), and microarray. The effects of AMM/I-conditioned cell medium (CM) on the activation of hepatic stellate cells (HSC) were analyzed in vitro and in vivo therapeutic assays were performed on a mouse liver fibrosis model. The engineered AMM/I expressed high levels of IL-10. AMM/I-CM inhibited the activation of HSC (in vitro) and TNF-α expression of T cells/macrophage derived from fibrotic liver. In addition, human IL-10 was detected in the serum of the mice transplanted with AMM/I and transplantation of AMM/I significantly inhibited thioacetamide (TAA)-induced liver fibrosis and ameliorated abnormal liver function. Furthermore, a high number of human albumin-expressing AMM/I were successfully engrafted into the liver of recipient mice. Overall, genome-edited AMMs overexpressing anti-fibrotic IL-10 might be a promising alternative therapeutic option for the treatment of liver cirrhosis.
