Fig. 6. Tead4-/- ES cells appear similar to and express the
same markers as wild-type cells. (A) Tead4+/+
and Tead4-/- ES cells generated from E2.5 embryos at
10x and 40x magnification. (B) ES cells derived from
embryos produced from Tead4 heterozygous matings were genotyped for
Tead4. (C) Semi-quantitative RT-PCR of RNA from
Tead4+/+ and Tead4-/- ES cells for
markers of pluripotentcy including Oct4, Fgf4, Nanog, Sox2 and
Rex1, and differentiation [brachyury (T) at 30 cycles], with
Gapdh as a reference. (D) Semi-quantitative RT-PCR analysis of
embryoid bodies generated from Tead4+/+ and
Tead4-/- ES cells at days 0, 1, 2, 4 and 5.
Differentiation markers include Rex1 for undifferentiated ES cells,
brachyury (T) (at 35 cycles) for mesoderm, Hnf4a and
Gata6 for endoderm, and Fgf5 for ectoderm, with
Gapdh as a reference control. W, wild type; M, mutant.
