La greffe de graisse autologue est une nouvelle option thérapeutique. Les tissus adipeux contiennent effectivement un grand nombre de cellules multipotentes (préadipocytes, cellules souches mésenchymateuses…)

Pour diminuer l’altération et la résorption partielle de la graisse, A-PRP est mélangé aux cellules adipeuses.

De grandes quantités de facteurs de croissance sont contenus dans le mélange (PDGF, TGF, IGF, EGF, VEGF, FGF), permettant la prolifération et la différenciation des cellules souches. La stimulation par l’A-PRP des fibroblastes et des cellules endothéliales contribuent à la survie de la graisse

Produit

RegenKit Extracell Adipocytes est conçu pour recueillir, laver et combiner le tissu adipeux du patient avec son propre plasma riche en plaquettes.


RegenKit Extracell Adipocytes - Dispositif médical de Classe IIb - CE0086

Utilisation prévue: Préparation de plasma autologue riche en plaquettes (A-PRP) et d'autres produits dérivés du plasma.

Preuve

Des études in vitro ont montré que l’adjonction 20 % de PRP autologue représente un moyen sûr et efficace pour favoriser la multiplication des cellules souches mésenchymateuses dérivées de l’adipose.

Par conséquent, le PRP devrait être considéré comme une alternative au sérum fœtal bovin ou d’autres dérivés sanguins non autologues dans les cultures cellulaires.1

Des études in vivo que le tissu graisseux et le PRP combinés diminuent la résorption des cellules de graisse post-transplantation, optimisent la survie des greffons graisseux, augmentent la prolifération cellulaire et facilitent les injections (création de moins de nodules graisseux).2-5
 
Par conséquent, RegenLab a conçu un kit dédié à la combinaison du tissu adipeux et du plasma riche en plaquettes (PRP) : le kit RegenExtracell® Adipocyte.

Skin Texture & Elasticity
A-PRP increases revascularisation, neo-callagenesis, tone, skin thickness and elasticity. It can be used as a standalone treatment or as a multi-treatment protocol combining technologies such as fractional laser, LED, chemical peels, dermal fillers, dermabrasion etc.6
Fibroblast proliferation is increased in the A-PRP group. This results in a doubling of the amount of collagen available within the extracellular matrix.3

The Patient’sPlatelet-RichPlasmastimulates cells to regenerate the skin’s connective tissue, resulting in accelerated healing post laser and chemical peels. It also improves the elasticity, tone and thickness of the skin and contributes to the remodelling of collagen fibres. 4-5
Examination of treated regions with A-PRP show new collagen formation, revascularisation, Glycosaminoglycans augmentation and anti-oxidant effect.6
Scars - Acne Scars
Treated scars have a noticeable improvement in colour, size and firmness. The use of A-PRP associated with microneedling is an innovative and represents a promising therapeutic treatment option for the management of keloid and pitted acne scars.7
Wrinkles & Dark Circles
RegenACR PLUS completes the RegenACR Kits line for the preparation of A-PRP® in Aesthetics, offering the exclusive PLUS technology for small to medium treated areas. 5,8,9

The combination of the patient’sPlateletRichPlasmaand its natural activator, Autologous Thrombin Serum (ATS) induces the formation of a biological glue and a three dimensional matrix, 100 % autologous. 8,9

Plateletsare stabilised at the treatment site for a long lasting growth factor delivery. 8,9
A-PRP delivery to the dermo-reticular area of the keloid scar allows for re-organisation of the tissues and decreasing mast cell proliferation and histamine release.7
