However, we observed a significantly higher percentage of Annexin V+ B cells under the influence of MSC factors compared to the control group of B cells in HVs (0.79 ± 0.40% vs. 0.56 ± 0.28%; p = 0.0059) and lupus patients (1.23 ± 0.67% vs. 0.65 ± 0.47%; p = 0.0007) (Figure 6A). The gene discussed is ANXA5; the disease is systemic lupus erythematosus.
