Rspo1-Wnt-vegfc signaling does not interact with Notch signaling. Vascular Notch signaling is not affected in rspo1 MO-injected animals. (A,B) Expression of mCherry in the mid-trunk of 24 hpf Tg(T2KTp1bglob:hmgb1-mCherry)jh11 transgenic Notch reporter embryos (Parsons et al., 2009) injected with either control MO (A) or rspo1 MO (B). Notch-dependent expression of mCherry in the vasculature (arrows) is unchanged in rspo1 MO- compared with control MO-injected animals. The expression of vegfc is not affected by ubiquitous heatshock-inducible transgenic activation of Notch signaling. (C,D) In situ hybridization of the mid-trunk of 24 hpf wild-type sibling embryos (C) or Tg(hsp70:Gal4)1.5kca4, Tg(UAS:myc-notch1a-intra)kca3 double transgenic embryos for heatshock-inducible activation of Notch signaling (D), as described previously by Lawson et al. (Lawson et al., 2001). Vascular expression of vegfc (arrows) is unchanged in Notch-activated embryos when compared with their control siblings. Lateral views, anterior towards the left. |
