The invention provides a method for building a vascularized
tissue engineering periosteum. The method is characterized by comprising the following steps: 1, preparing a macromolecular micro / nano-fibermembrane by an electrostatic
spinning method; 2, inoculating seed cells to the nano-
fiber membrane, performing cultivation
in vitro and performing directional induction for a period of time; 3, implanting a seed
cell / nano-
fiber membrane composite body subjected for in-vitro directional induction for a period of time
in vivo, performing in-vivo vascularization for a period of time and then takingout to obtain the
tissue engineering periosteum. By the method, the rejection reaction of an
autologous tissue can be effectively reduced and the vascularization degree of the
tissue engineering periosteum can be greatly increased; furthermore, the tissue
engineering periosteum is vascularize
in vivo in advance, so that the integration time of a
blood vessel at the defect position and a
blood vessel of the implanted tissue
engineering periosteum can be shortened, the healing process of the
bone defect is shortened, and the method has a very wide application prospect in the fields of
wound healing and tissue
engineering.
