Fig. 5. mypt1 is expressed in the LPM and endoderm cells.
(A) Northern blot analysis of mypt1 expression in unfertilized
embryos (unf), 12-hpf and 1- to 5-dpf embryos, and adult liver (adl).
(B) Lateral and dorsal views of zebrafish embryos subject to WISH using
the mypt1 probe. fe, foregut endoderm; hd, head region; sm, somites.
(C,D) Sectioning of WISH embryos (34 hpf) with the (C)
mypt1 single probe or (D) prox1 (red) and mypt1
(purple) double probe. Black arrow, liver primordium; green arrow, left LPM;
yellow arrow, right LPM. nt, neural tube.
