Abstract
The invention discloses a soft tissue filler of platelet rich plasma, which comprises autologous PRP, autologous SVF and a scaffold material, and is prepared by mixing the autologous PRP, the autologous SVF and the scaffold material. The support material provides a reliable three-dimensional growth environment for SVF, improves the survival rate of adipose-derived stem cells, and promotes the regeneration of adipose-derived cells, and on the other hand, the support material realizes the repair of soft tissue defects by virtue of physical space occupation, so that the mixture can promote the regeneration of tissues while realizing the repair of tissue defects. The soft tissue filler prepared by the invention has the advantages of easy revascularization after injection, slight inflammatory reaction, safety and reliability, and is suitable for soft tissue filling, sunken deformity caused by soft tissue defect repair, and facial and body beautifying and shaping.
Description
Technical Field
The invention belongs to the technical field of plastic cosmetology, and particularly relates to a soft tissue filler of Platelet Rich Plasma (PRP) and a preparation method thereof.
Background
With the improvement of living standard, people have higher and higher requirements on the appearance of the temperament, and the anti-wrinkle effect has become the demand of more and more people. People have higher requirements on the safety of related products while pursuing beauty. Traditional subcutaneous injection of hyaluronic acid can achieve temporary wrinkle removal, but the effect is not durable enough, and once the implant material degrades, wrinkles and depressions reappear.
Autologous fat, which is derived from autologous tissue, does not have a risk of immunological rejection, has good compatibility, and is considered as the most ideal orthopedic implant, but the greatest problem after fat transplantation is that the survival rate is too low, fat liquefaction easily occurs, the effect is maintained for a short time, and the application of fat transplantation is severely limited.
Chinese patent CN 104739862A discloses a mixture of PRP and SVF, which is directly mixed for cosmetic injection filling. The composition can improve certain filling effect compared with the single use of PRP, but PRP can not provide reliable three-vitamin long space for SVF, and has low cell survival rate and short wrinkle repair duration. In addition, the PRP source of the invention is cord blood, not autologous blood, and also risks of viral transmission and immune rejection.
In summary, in the aspect of cosmetic injection filling materials, a pure sodium hyaluronate filling agent, autologous fat transplantation filling and a filling agent mixed with autologous fat extract and PRP are all applied, and the integral injection cosmetic market is mixed with fish dragons, but products with good true compatibility, long maintenance time and few complications are not abundant. In combination with the appeal of the beauty seeking people, the market needs an injection beauty filling product with high safety, good compatibility and long lasting time.
Disclosure of Invention
In view of the above problems, the present invention provides a soft tissue filler of Platelet Rich Plasma (PRP), which overcomes the disadvantages of the conventional hyaluronic acid alone and PRP with short filling duration or poor tissue regeneration promoting ability. Also provides a preparation method of the filler.
One technical scheme of the invention is that the soft tissue filler comprises autologous PRP, autologous SVF and a scaffold material; the scaffold material is a biodegradable material or an autologous component which can be accepted by organisms.
The SVF is a vascular stromal component (vascular stromal) in adipose tissue, is a cell mixture, comprises stromal cells, high-concentration adipose-derived stem cells, blood cells such as vascular endothelial cells, white blood cells and red blood cells, and can promote growth factors of the surrounding environment such as: PDGF, EGF, FGF, VEGF, IGF and the like are secreted, so that the angiogenesis function is promoted, and the survival rate of various cells is improved; on the other hand, SVF has an immunomodulatory effect and is able to reduce inflammatory responses.
The scaffold material can be selected from commercialized products or prepared by self, and is made of biodegradable materials or self-components acceptable by organisms, and the material comprises any one or combination of several of collagen, hyaluronic acid, sodium hyaluronate, polylactic acid, hydroxyapatite and self fat.
The bracket material is a common clinical injection filling material, and is safe and reliable. The use of the scaffold material can provide support and space for the new cells, and is convenient for the growth of the cells and the growth of new blood vessels; in the initial stage of transplantation, the scaffold material can play a good auxiliary type effect, and along with the metabolic absorption of the scaffold material, the new tissue fills the original space of the scaffold material, so that the overall filling effect and the tissue survival rate are improved.
Preferably, the number of viable cells of autologous SVF per 10ml of soft tissue filler is 106-107(ii) a The number of platelets was 105-107(ii) a The volume ratio of the autologous PRP to the autologous SVF is 1:1, and the volume of the scaffold material is 1-4 times of the total volume of the autologous PRP and the autologous SVF.
The invention also provides a preparation method of the soft tissue filler, which comprises the following steps:
step 1, preparation of autologous PRP

Example 1
Step one, preparation of PRP
20mL of autologous blood was collected, and sodium citrate anticoagulant (2.2 mL of 3.8% aqueous sodium citrate solution) was added. First, whole blood was centrifuged at 250 Xg for 8 min; sucking the upper plasma layer into a new centrifuge tube at 700 Xg, and centrifuging for 6 min twice; removing part of plasma, and resuspending the pellet in the remaining plasma to obtain PRP with a volume of about 1.0 mL. The number of platelets in PRP was 8.2X 108And (4) respectively.
Step two, preparation of SVF
Extracting 20mL of adipose tissue, standing for 20 min at room temperature, removing tumescent liquid in the anesthesia process to further purify fat, and removing a liquid part to obtain 15mL of fat particles; adding 15mL of normal saline for washing, centrifuging at 1200r/min at 21 ℃ for 6 min, and removing liquid part to obtain 10mL of solid fat particles. Adding 10mL of collagenase solution (200U/mL) prepared by normal saline, carrying out shake digestion at constant temperature of 37 ℃ for 40min, collecting the digestion solution, centrifuging at 1000r/min and 21 ℃ for 8 min, removing the supernatant, taking cell sediment, adding 6 mL of normal saline, centrifuging at 800r/min and 21 ℃ for 6 min, taking cell sediment again, and carrying out resuspension by using 1mL of normal saline to obtain the fat SVF. Counting with a cell counter to obtain total cell number of 4.2 × 107The cell survival rate is 89 percent, and the total number of living cells is 3.7 multiplied by 107And (4) respectively.
Step three, mixing the preparation
The stent material of the present example was selected from commercially available Rayleigh blue®2 modified sodium hyaluronate gel for injection.
First, 0.1M CaCl was added to the PRP2Solution (50 muL CaCl added per 1ml PRP)2Solution of CaCl2For activating PRP to form a gel), 0.5mL of the solution was taken, mixed with 0.5mL of SVF, and finally mixed with 1mL of rayleigh blue®2, mixing the hyaluronic acid stent by adopting a luer syringe. The obtained preparation has platelet number of 4.1 × 108Number of viable cells of SVF was 2.1X 107And (4) respectively.
As shown in fig. 1, with the addition of the scaffold material, blood circulation around the implant was good and new blood vessels were clearly visible. As can be seen from FIGS. 3, 5 and 6, hyaluronic acid provides a three-dimensional space for SVF cells, local blood circulation is good, and the survival rate of the cells is high; and with hyaluronic acid degradation, PRP and SVF cells have obvious effect of promoting regeneration of peripheral tissues, and the overall maintenance time is longer.
Example 2
