Abstract

Poly (2-hydroxyethyl methacrylate), polyHEMA, is known to prevent cellular attachment and spreading. This hydrogel is used to culture cells not dependent on anchorage. Blending polyHEMA with a copolymer of methyl methacrylate and acrylic acid introduces negative charges to the hydrogel and improves its mechanical characteristics. PolyHEMA and the blend were tested for attachment and proliferation of Vero cells. Dense and porous samples of the hydrogels were used. Attachment assays included cellular quantification with MTT photometry and cellular morphology with the scanning electron microscopy after 2 h culture. Proliferation assays were carried out with 5 and 10 days culture. Cellular morphology included cytochemistry of resin sections and scanning electron microscope observations. Hydrogels allowed a few cells to attach and proliferate. The cells growing on the surface of hydrogels were organized in various layers and showed a differential morphology. Cells located inside the pores remained rounded. The hydrogels showed the possibility of inducing differentiated phenotypic expression.
