Cytokine and cytolytic granule production of CD8+ T cells remained unchanged in the CM from eMSCs group in the LPS-stimulated condition, while CM from AD-MSCs slightly decreased cytolytic granule production, and CM from UC-MSCs slightly increased TNF-α and cytolytic granule production (Additional file 3: Fig. S2C-E). This evidence concerns the gene CD8A and Alzheimer disease.
