PhytoCellTecTM Malus Domestica Innovation Price

• BSB Innovation Price for most innovative natural active

• Received during incosmetics 2008

• Patent pending in CH, EU, USA and Korea


1. Plant Cell Cultures

• New cell culture technology makes it now possible to cultivate cells of endangered and rare species

• Selected plant material (leave, fruit) is wounded to induce the formation of a callus tissue

• The callus of a plant consists of dedifferentiated, totipotent cells (plant stem cells)


The 3 Steps of PhytoCellTec

1. Preparing a sterile plant preparation

2. Wounding the plant to induce callus tissue

3. Growing callus cells in liquid cultures


Plant Cellculture Technology (PhytoCellTecTM =PCT)

• Suspension cultures from plant stem cells are grown in bioreactors

• Medium consists of sucrose, trace elements and plant hormones (cytokinins and auxins)

• Cultures grow with oxygen and without light (chlorophyll free)• Batch is harvested after all sugar has been metabolized• The cells are washed and homogenized to release the secondary

metabolites• Oil- and water-soluble ingredients are extracted by liposomal

structures


2. Swiss Apple Story


Storage Ability of Apples and Skin Aging

• Apples with very good storage abilities stay fresh over months

• This was an important factor for cultivar selection

• Modern apple cultivars are selected for intensive cultivation and for a sweet flavour since storage is no longer a problem

• Therefore cultivars with excellent storage abilities disappeared from the market


Uttwiler Spätlauber

• An old cultivar is still alive in Switzerland but no longer cultivated

• The Spätlauber variety derives from the middle of the 18th century

• It was famous for its tremendous storability without shrinking

• Today this is a very rare and endangered apple variety with only a few trees left in the world


Uttwiler Spätlauber

The importance of the Uttwiler Spätlauber apple was honored by the release of a stamp.


Young and Old


The Secret of Storage Ability

• High acid and tannin concentrations • Longevity of cells• Undiscovered factors?

This apple can only be used by PCT

3. Stem Cell Cosmetics


What are Skin Stem Cells?

Properties of skin stem cells:

• Self-renewal - the ability to go through numerous cycles and cell divisions while maintaining the undifferentiated state

• Differentiation - the capacity to differentiate into other cell types of the same tissue

• Primary roles - replenish dying cells and regenerate damaged tissues


Adult Stem Cells in Skin

In skin, different types of stem cells have been found:

Type Place

Epidermal skin stem cells Basal layer of the epidermis

Hair bulge stem cells Hair follicle


Epidermal Stem Cells

Stem cells are located in the basal layer where 2-7% of the cells are stem cells

Differentiating progeny of one epidermal stem cell

Epidermal stem cell

Transient amplifying cells

Basement membrane

Dermis

Basal layer

Spinous layer

Granular layer

Stratum corneum


Hair follicle matrix

Epidermal layer

Sebaceous gland

Hair shaft

Inner root sheath

Outer root sheath

Basal layer

Dermal papilla

Hair bulge stem cells

Infundibulum

Lineages derived from bulge stem cells

Differentiation pathways supplied by bulge stem cells

Hair Bulge Stem Cells


Stem Cells and Aging

• Stem cells have a limited life expectation

• Environmental and intrinsic stress factors effect stem cells

• In aged skin the number and activity of stem cells is reduced

• Skin stem cells have to be protected and supported to delay preliminary aging


Epigenetic Factors Composition of Plant Stem Cells

• Plant stem cells contain similar epigenetic factors as human stem cells

• Plant stem cell extracts provide important nutrients to human stem cells

Plant stem cell nutrients improve the viability and healthiness of human stem cells


PhytoCellTecTM Malus Domestica Provides two Different Modes of Activity

1. Use of plant stem cells to protect skin stem cellsThe components of plant stem cells such as Malus domestica are rich in specific factors relevant to protect and maintain the function of skin stem cells

epigenetic factors

2. Use of longevity cell extract to delay skin aging The apple Uttwiler Spätlauber is known to contain ingredients which insure longevity of cells

metabolites


Novel Progenitor Cell Targeting Technology

• Biopsy: human epidermal cells ca. 6% of cells are stem cells (optically not different from normal basal cells)

• Medium: specifically designed, fully defined medium that mimics the physiological environment of the in vivo stem cell niche enrichment of so called progenitor cells (stem cells)

3x


Activity Assay for Epidermal Stem Cells

Stimulation of growth or over-expression of markers are not good parameters for the activity of stem cells

• Colony forming efficiency (CFE)

Cell cultures are seeded at low density. The number of colonies formed is a value for the concentration and activity of progenitor/stem cells

Epidermal progenitor (stem) cells of late passage (P14) loose the capacity to form a 3D epidermis. But when these cells are cultured with PhytoCellTecTM Malus Domestica, they retain the capacity to form a 3D epidermis similar to early passage progenitor cells.

PhytoCellTecTM Malus Domestica clearly helps to conserve the progenitor cell characteristics. Also cells of late passage are able to proliferate and to undergo the complex process of stratification and differentiation.
