FIG. 1.
Fibronectin expression is restored in cadherin-transfected cells by transient cotransfection of β-catenin or Xwnt-8 or by lithium treatment. (A) Immunoblot analyses of fibronectin expression with monoclonal antibody 6D9, specific for Xenopus fibronectin. (B) RT-PCR analyses showing the 550-bp fragment of fibronectin and, as an internal standard, the 220-bp fragment of histone H4.
