Fig 7. Blood-brain barrier function is impaired after loss of hb expression in carpet cells.

Fig 7

(A) After injection of fluorescently labelled dextran into the abdomen of adult flies, animals with correctly formed blood-brain barrier show no fluorescence in the compound eye. (A’) In flies with incomplete blood-brain barrier, fluorescent dye can be observed in the compound eye as well as in the body. (B) Quantification of eyes with (green) or without (red) dye penetration. hb knock-down flies have a significant increase in the penetrance of dye into the eye, indicating a defective blood-eye barrier. Pearson’s Chi-squared test was performed to determine significance between the wild type results and the RNAi. ***: p-val < 0.0005.
