Benefits of technology

[0037]The main object of the present invention is to create a cosmetic preparation which protects stem cells against intrinsic and extrinsic stress factors, in particular promotes the proliferation of stem cells and protects them against apoptosis.

Problems solved by technology

Unfortunately, for human beings this ability is restricted to the embryonal phase.
However, the capacity of these abilities may be disturbed by genetical problems, environmental influences and the aging process.
However there are restrictions with respect to the use of plants or plant components. i.e.:The availability may be restricted, e.g. by the seasons, limited storage capacities, protection of species, problems in cultivation, or bad harvests.The quality is not unchanging, e.g. due to seasonal variations, different cultivation methods, geographic differences, different suppliers, clones, pollution of the environment, or physical status.
These facts often make the use of plants in cosmetic applications impossible.

Production of a Dedifferentiated Plant Cell Culture

[0079]Mature apples of the cultivar Uttwiler Spaetlauber were rinsed with tap water. In cylindrical pieces of a diameter of about one centimeter diameter the score was out along the axis of the by means of a cork borer. For the surface sterilization, the cylinders were dipped for 30 seconds into 70 percent ethanol and thereafter for 10 minutes into 2.5 percent sodium hypochloride containing 0.1 percent of the surfactant Tween 40. Thereafter, the sterilized cylinders washed tree times with distilled water, cut into slices of about 3 millimeter thickness, and placed on a solid medium of the following composition per liter:

Calcium chloride332mgPotassium dihydrogen phosphate170mgPotassium nitrate1900mgMagnesium sulfate180.54mgAmmonium nitrate1650mgCobalt chloride hexahydrate0.025mgCopper sulfate pentahydrate0.025mgIron-Sodium-EDTA36.7mgBoric acid6.2mgPotassium iodide83mgManganese sulfate hydrate16.9mgDisodium molybdate dihydrate0.25mgZi...

Production of a Suspension Culture

[0082]Dedifferentiated cell clumps growing on said solid medium were taken, homogenized and placed into the same medium without gelling agent. A finely dispersed suspension was obtained which could be use for larger cultivation systems. The suspensions were grown in the dark at 25 centigrade and a shaking velocity of about 100 rpm.

Outbreak

[0083]One tenth of a fully grown culture (percentage of cells being about 50 percent of the total weight of the culture) was used for the seeding of the next volume step. The scale-up was effected in a one-way bag reactor system of Wave Biotech AG, Tagelswangen, Switzerland (so-called Wave Reactor). The scale-up was effected in steps of 1 / 10 / 25 liter. The temperature was held at 25 centigrade and the aeration at about 0.1 vvm. Various mixing speeds were applied in dependence of the bags used. Cultivation was carried out in the dark, and it took about 20 days until a bag was completely grownup.

Abstract

The present invention relates to the use of dedifferentiated plant cells in cosmetic preparations for protecting of stem cells against intrinsic and extrinsic stress factors, in particular for promoting proliferation of stem cells and for protecting them against apoptosis. In particular, the invention relates to the use of dedifferentiated plant cells from fruits of Malus domestica (Apple) cultivar Uttwiler Spaetlauber. Further, the invention relates to a method for cultivating of dedifferentiated plant cells, as well as to the preparation of extracts of plant cell cultures which are suitable for such applications.

Description

FIELD OF INVENTION[0001]The present invention relates to the use of dedifferentiated plant cells in cosmetic preparations for protecting of stem cells against intrinsic and extrinsic stress factors, in particular for promoting proliferation of stem cells and for protecting them against apoptosis. In particular, the invention relates to the use of dedifferentiated plant cells from fruits of Malus domestica (Apple) cultivar Uttwiler Spaetlauber. Further, the invention relates to a method for cultivating of dedifferentiated plant cells, as well as to the preparation of extracts of plant cell cultures which are suitable for such applications.BACKGROUND OF THE INVENTION[0002]Stem cells (SC) are uniform undifferentiated cells having the property of constant regeneration and the unique ability of turning into any other cell type by cleavage and differentiation. By said potential, SC are a renewable source of human tissue. Thus, SC became an important object of medical research for various ...
