Figure 4. Prospero expression in ISCs is regulated by the Robo2 pathway.
(A) Representative images of pros+pH3 double positive cells in the posterior midgut of wild-type flies.
(B) Quantification of the proportion of pros+ cells among dividing pH3+ positive cells in control flies or after knocking-down Robo2 expression in esg-positive cells for 10 days. n represents the number of independent experiments, the numbers indicated below the genotypes represents the total number of pH3+ cells counted.
(C) Representative images of esgGal4>mCherry pH3+ pros+ cells.
(D) Representative image of a mitotic cell expressing both the Delta and Prospero proteins (See Figure S3C for additional examples).
(E) Adult specific knock-down of Prospero in ISCs leads to a decrease in the proportion of EEs in the intestine.
(F) Knock-down of Prospero in esg-positive cells suppresses the increased proportion of EEs induced by leaRNAi expression.
n indicates the number of guts analyzed in B, E and F. p-value from two-tailed Student's t-test. NS, Not Significant. See also Figure S3.
