23 Jul Decellularized fiber ring matrix preparation method
Abstract
The invention discloses a decellularized fiber ring matrix preparation method and belongs to the technical field of animal cells or tissues. The decellularized fiber ring matrix preparation method includes taking spinal fiber ring of a healthy adult pig, sufficiently rinsing the spinal fiber ring by sterile saline solution; placing the spinal fiber ring into Tris buffer solution of concentration 10mM and with 0.05-0.5% of EDTA (ethylene diamine tetraacetic acid) and 5-50KIU/ml of aprotinin and oscillating at the temperature of 4 DEG C; then placing the spinal fiber ring into the Tris buffer solution containing 1-5% of TritonX-100, oscillating at room temperature; placing the spinal fiber ring into Tris buffer solution containing 0.05-0.5mg/ml of deoxyribonuclease, 5-50microgram/ml of ribonuclease A, and oscillating; and finally, washing by sterile saline solution with oscillating, and storing in sterile PBS (phosphate buffer solution) at the temperature of 4 DEG C. The decellurlarized fiber ring matrix preparation method is simple in preparation process, thorough in decellurlarization and complete in reserved structure, similar in matrix content and mechanical performance as those of natural fibers, and is a good tissue engineering fiber ring support material.
