title: [Preparation of a composite membrane with collagen scaffold material for tissue culture].
abstract: OBJECTIVE
  To prepare a composite membrane with collagen scaffold material for tissue culture.
  
  
  METHODS
  Pure collagen membrane, collagen/hyaluronic acid (HA) membrane, collagen/chitosan membrane and collagen/chitosan/ HA membrane (abbreviated as composite collagen membrane) were prepared respectively, and their respective biodegradation time and the number of the cells proliferated on them were examined in vitro.
  
  
  RESULTS
  The biodegradation time of pure collagen, collagen/HA and composite collagen membranes in vitro was 1 380, 1 376 and 1 560 min respectively, and the number of cells proliferated on the collagen/HA membrane and the composite collagen membrane were greater than that on the pure collagen membrane.
  
  
  CONCLUSIONS
  Addition of chitosan can decrease the biodegradation of the collagen membrane in vitro, while HA can not; HA Can contribute to cell adhesion and proliferation on the collagen membranes, but chitosan does not.
