Z-stack images of the KhES-1 colonies treated or untreated with AP for 2 days
Description
Z-stack images of expression of E-cadherin and F-actin. After AP treatment, morphological changes suggestive of a transition from columnar to squamous epithelium, an anatomical feature distinguishing amniotic ectoderm from the epiblast, were observed. AP treatment is addition of the two inhibitors for the ACTIVIN/NODAL and FGF signaling.
