UMSCs target LPS-induced T-cell compartments shift in PBMCs from AIS patients. Frequency and distribution of T cell compartments among CD4⁺ (A) and CD8⁺ (B) T cells under various coculture conditions. Data are represented as percentages of total CD4⁺ (A) and CD8⁺ (B) T cells. The pie charts show the mean relative proportions of different T cell compartments within the CD4⁺ (A) and CD8⁺ (B) T cell populations across different coculture systems. Statistical data are presented as scatter plots with mean values and SD. Comparisons were performed using one-way ANOVA with the LSD post hoc test or Welch’s t-test with Dunnett’s post hoc test, with p < 0.05 considered statistically significant. *p < 0.05, **p < 0.01, and ***p < 0.001
