Fig. 7. Transfating of pronephric cells in the mind bomb mutant. (A,B) shippo1 expression in control wild-type embryos is restricted to single cells (A), whereas, in mind bomb homozygotes (B), pronephric distal segment cells (ds) are uniformly positive and there is an increase in shippo1-positive cells in the proximal segment (ps). (C,D) Wild-type jagged 2 expression (C) is also expanded in mind bomb homozygotes (D). (E,G) trpM7 (E) and slc13a1 (G) expression is almost completely lost in mind bomb homozygotes (F and H, respectively).
