The results at the cellular level showed that EI24 was significantly elevated in NASH, and the level of EI24 was significantly overexpressed after treatment (Supplementary Fig. 20 online); meanwhile, at the animal level, the p-EI24 protein level was significantly increased after the action of HucMSC-Ex (Supplementary Figs. 21–26 online). The gene discussed is EI24; the disease is metabolic dysfunction-associated steatohepatitis.
