Freshly isolated uncultured adipose tissue-derived stromal cells (u-ADSCs) are useful for regenerative therapy. However, the detailed characteristics and therapeutic efficacy of u-ADSCs obtained from disease-affected hosts are unknown. We compared the properties and therapeutic efficacy of u-ADSCs obtained from wild-type mice and from a mouse model of non-alcoholic steatohepatitis (NASH). Wild-type u-ADSCs and NASH-derived u-ADSCs did not show marked differences as well as their therapeutic effects on NASH-related cirrhosis resulted highly similar, including reductions in inflammation and fibrosis. NASH-derived u-ADSCs, similar to wild-type u-ADSCs, are applicable for reparative and regenerative therapy in mice with NASH.
