Administration of cord blood cells with plasma in the 6-OHDA PD rat model: Assessment of immune cell activation, and pro-inflammatory cytokine production in the intestine. Confocal imaging shows a significant reduction in OX-6 (MHC II) expression in the intestinal mucosa of 6-OHDA animals that were given a combination of cord blood cells and plasma. This therapy also resulted in a significant decrease in TNF expression in this animal model. Quantitative analyses of the estimated OX-6 expression and TNF are displayed in the graphs above. Representative merged images above show co-localization of OX-6 (Green) or TNF (Red) with DAPI+ (Blue) expression from cells in the small intestine of 6-OHDA PD animals. Arrow heads indicate positive staining of OX-6 and TNF expression in intestinal villi. Scale bar = 100 μm
