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.
Result:
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.
