Fig. 4. TEAD4 is required for the formation of a blastocoel cavity, but not
through regulation of cadherin 1 (Cdh1). (A) E3.5 embryos
were treated as in Fig. 3,
except that they were immunostained with anti-CDH1 antibody (green).
(B) Schematic representation of the relationship between transcription
factor TEAD4 and other genes and events in the establishment of the
trophectoderm lineage. Upward and downward pointing arrows indicate increased
and decreased expression, respectively.
