Abstract

A tissue engineering particle tissue and preparing process is characterized in that the tissue engineering particle tissue which is formed by cells to be compounded on micro-carriers comprises larger particle tissues which are formed by mutual connection of a plurality of particle tissues. The invention uses the tissue engineering technology to culture highly active tissue engineering particle tissues to implant in the body for repairing defected tissues and organs. The invention has a good cell growth state and higher cell activity, and can clinically solve the difficulties of less donor tissues and large repairing area, and the micro-carriers can finally be degraded, after the body is cured, no influences can be caused to the body. In the clinical treatment, the invention can be used as a transplant for repairing large area tissue defection and as filling material for repairing body depressed deformation, and can be transplanted to wound surfaces. The invention can also be used by injection, and is extensive in application range and convenient in utilization.

Description

technical field

[0001] The invention belongs to the technical field of tissue engineering of biological materials, and in particular relates to a tissue engineered microparticle tissue and a preparation method thereof. Background technique

[0002] In the field of surgical repair, the problem of insufficient skin source is often encountered, especially the large-scale skin defects caused by large-scale deep burns bring difficulties to surgery and treatment. Micro-skin technology is a commonly used autologous skin transplantation technique in clinical practice of burns. When the autologous skin is seriously insufficient, the remaining limited skin source of the patient is used to physically make it 0.5mm 3 ~1mm 3 The skin fragments are scattered and transplanted on the wound at a certain interval, and the proliferation ability of skin cells is used to form skin islands and gradually connect with each other to heal the wound; its advantage is that it can maximize the use of i...
