In vivo cell viability in the implanted films. a. Cells adhered well when the film was not treated. b. Higher magnification shows cell-adhering filopods with normal shapes. c. Few cells or cell residues are shown from the treated film. d. Higher magnification shows morphological changes and the loss of cell-adhering filopods. e. Histogram from three readings shows the difference in cell adherence rate in the control group compared with the nontreated group (P < 0.0131)
