23 Jul Transplanting material of fat granule tissues compounded with SVFs (Stromal Vascular Fractions) and PRFs (Platelet-Rich Fibrins) as well as preparation method and application thereof
Abstract
The invention belongs to the technical fields of tissue engineering and biological materials, in particular to a transplanting material of fat granule tissues compounded with SVFs (Stromal Vascular Fractions) and PRF (Platelet-Rich Fibrins) as well as a preparation method and application thereof. The transplanting material comprises fat granules, SVFs and PRF membrane granules. The preparation method comprises the following steps of: extracting fat granules from a patient by adopting liposuction, additionally extracting SVFs obtained by fat granule digestion from the same patient and extracting PRF membrane granules obtained by blood centrifuging from the same patient; mixing the SVFs with the PRF membrane granules; incubating at the temperature 37 DEG C for 10 minutes; and mixing the fatgranules, the SVFs and the PRF membrane granules to obtain the transplanting material of fat granule tissues compounded with the SVFs and the PRFs. The material can be applied to soft tissue molding and soft tissue defect repairing; by adopting the material, the absorption of transplanted fat tissues is effectively reduced, and the fat transplanting effect is improved.
