23 Jul Shell and tube orientation arrangement structure cell holder and its preparation method
Abstract
The present invention relates to a shell-and-tube orientation arranged structure cell scaffold and its preparation method. The material of said cell scaffold includes synthetic aliphatic polyester bio-degradable high-molecular material or natural bio-degradable high-molecular material or their mixture, in the material the growth factor bio-degradable active substance or bio-degradable inorganic substance is contained and used as third component. The solvent for preparing shell-and-tube orientation arranged structure cell scaffold is first solvent or first solvent in which the second solvent is mixed. Said invention adopts a progressively cooling technique from bottom to top, cooling speed is 0.01-2.5deg.C/min and cooling range is t37 to-196deg.C, finally the shell-and tube orientation structure cell scaffold for tissue engineering can be obtained. Said invention also provides the concrete structure of said cell scaffold and the concrete steps of its preparation method.
