driven by the Cx45 promoter in place of endogenous Cx45
expression. A) Wild-type B-E) Heterozygous Cx45 knockout,
F) Homozygous Cx45 knockout.

A micropipette injects fluorescent dye into the middle cell,
which then slowly spreads through gap junctions into neighboring
cells. (Image Provided by Richard Francis)

migration in cultured embryo sections demonstrating primordial
germ cell migration in mouse embryos (embryonic day 9.5).
Primordial germ cells appear fluorescent because they contain
the transgene Oct4-EGFP.
