Figure 5. Cell transmembrane receptor expression.

A) Fluorescence micrographs of β1- and α6-integrin, and E-cadherin and Junctional Adhesion Molecule (JAM)-A expression after two days of culture of HepG2 on PS, ParC/PDMS, or PDMS substrata. Bare scale  = 50 µm. B: Fluorescence intensities normalized to 10⁶ cells, of β1- and α6-integrin and E-cadherin and Junctional Adhesion Molecule (JAM)-A expression after two days of culture on PS, ParC/PDMS, or PDMS substrata. Data are expressed as mean of nine normalized values obtained from three separate experiments.
