Using the atomic force microscopy methods the morphology of cell structures, cultivated on films from collagen and chitosan fibers, has been studied. The specific features of the growing cells morphology on a submicron level have been investigated, in particular, it has been shown that the number of the flagella of diameter up to 100 nm of the cells grown on the films from the collagen and hitosan fibers is larger than that one of the control samples, grown on glass substrates.
