- the cells were covered with a solution of PBS / 1% BSA (Albumin, from bovine serum, Sigma), for 30 minutes, at room temperature.
- PBS / 1% BSA Albumin, from bovine serum, Sigma
- the 1% PBS / BSA solution was then replaced with a primary antibody solution corresponding to each labeled protein (see Table 1) diluted in PBS / 1% BSA.
- the plates were incubated overnight at 4 ° C.
- the cells were then rinsed three times with PBS and covered with a solution of secondary antibodies depending on the primary antibody to be targeted (see table 2) and DAPI at 1 / 500th (4 ', 6'-diamidino-2- phenylindole, dihydrochloride, Invitrogen Molecular Probes) diluted in PBS / BSA 1%.
- the plates were stored for one hour in the dark at room temperature.
- the plates were scanned with ArrayScan XTi from Thermo Cellomics.
- the images were then analyzed using Spot detector image analysis software, a bio-application developed for the arrayscan system.
- This program (pipeline) makes it possible to detect the red labeling of the targeted protein, corresponding to its expression.
- the area of the measurement area is delimited as the entire area of the image.
- the number of cells is determined by counting the nuclei by detecting the blue labeling.
- Aquaporins are a class of membrane proteins that form "pores" or channels permeable to water molecules in biological membranes. They allow the supply of water from the deep layers to the superficial layers, the AQP3 expressed in the lower part of the epidermis thus plays a fundamental role in establishing the flow of trans-epidermal water. Its interest in regulating skin hydration has been particularly studied by the Applicant.
- the dermo-epidermal junction or epidermal basement membrane is the acellular region which separates the dermis from the epidermis. It is a mechanical support for the adhesion of the epidermis to the dermis, controls exchanges and plays a fundamental role during skin re-epidermization by serving, through the glycoproteins which constitute it as a support for the adhesion and migration of the skin. keratinocytes. Nidogen (also called entactin), is a glycoprotein found at the level of this basal layer which allows the assembly of the constituents of this basal layer. The results of FIG.
- Collagen 1 is part of a family of so-called structural proteins present in fibrillar form in the dermis. It is abundantly present in the extracellular matrix (ECM), this support protein gives tissues mechanical resistance to stretching. Procollagen is the soluble precursor of type 1 collagen. The deposition and assembly of collagen fibrils in ECM is a complex process involving several proteins including the structural protein fibronectin.
- results of FIG. 4 show that the treatment with pomegranate extract alone leads to a significant decrease in the expression of fibronectin by 6%, while the peony extract alone significantly increases the expression of 5% fibronectin.
- the combination of the two extracts produces a potentiation effect, allowing a significant increase in the expression of fibronectin by 15%.
- the results show that the combination of the two extracts according to the invention exhibits synergistic effects, or even potentiation effects, and therefore a benefit for the maintenance of the cutaneous extracellular matrix.
- This combination of extract therefore makes it possible to prevent and / or reduce the loss of volume, the loss of firmness, the loss of elasticity and the reduction in the thickness of the skin. 3. Examples of formulations
