Temporal expression of canonical Wnt signaling components in in vivo and SCNT embryos. The relative fold-change of each gene was calculated following normalization to the expression level of β-actin in SCNT embryos at the 2-cell stage (Fz4 at the 4-cell stage). SCNT, somatic cell nuclear transfer; Fz4, frizzled homolog 4; Fz3, frizzled homolog 3; APC, adenomatous polyposis coli; GSK, glycogen synthase kinase; LEF1, lymphoid enhancer binding factor 1; PPAR δ, peroxisome proliferator activated receptor δ.
