Levels of cytokines in PDR, ED and MH vitreous used for tubulogenesis assay.

The cytokine levels were analysed by cytokine bio-chip array for 5 PDR, 2 ED vitreous (indicated by †) and the remaining (PDR = 5, ED = 3, MH = 4) by sandwich ELISA (indicated by*). The values in the table represent the mean concentration duplicate of each sample. For the two ED (†) samples, cytokines not included in this table are: IL-2, 8.1 pg/ml; IL-4, 7.14 pg/ml; IFN- γ, 12.8 pg/ml and less than 1.6 pg/ml for IL-10, TNF-α, IL-1α. 0- Less than the detectable limit; - cytokine not analysed; > Higher than the maximum detectable limit. PDR - Proliferative diabetic retinopathy; ED - Eales' disease; MH - Macular Hole.Levels of cytokines in PDR, ED and MH vitreous used for tubulogenesis assay.
