The present application relates to a kind of
polymer composite
microcarrier and its preparation method.It includes:
microcarrier body, the
microcarrier body includes
synthetic polymer, the microcarrier body is hollow structure, the
axial length of the microcarrier body is greater than the radial length of the microcarrier body;Functional area, the functional area is microporous structure, the functional area is formed on the microcarrier body, and the functional area includes natural
macromolecule, or, the functional area includes natural
macromolecule and inorganic salt.The
polymer composite microcarrier of the present application can make
cell adhere to the outer surface of hollow microcarrier, and the internal hollow structure can facilitate the flow of liquid, provide uniform, good microenvironment for large-scale expansion of
cell, it is advantageous to improve the number of
cell expansion.
