3 © Mibelle Biochemistry, Switzerland 2010 PhytoCellTec TM Malus Domestica Innovation Price BSB Innovation Price for most innovative natural active Received during incosmetics 2008 Patent pending in CH, EU, USA and Korea

4 © Mibelle Biochemistry, Switzerland 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)

5 © Mibelle Biochemistry, Switzerland 2010 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

6 © Mibelle Biochemistry, Switzerland 2010 Plant Cellculture Technology (PhytoCellTec TM =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

7 © Mibelle Biochemistry, Switzerland Swiss Apple Story

8 © Mibelle Biochemistry, Switzerland 2010 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

9 © Mibelle Biochemistry, Switzerland 2010 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

10 © Mibelle Biochemistry, Switzerland 2010 Uttwiler Spätlauber The importance of the Uttwiler Spätlauber apple was honored by the release of a stamp.

15 © Mibelle Biochemistry, Switzerland 2010 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

16 © Mibelle Biochemistry, Switzerland 2010 Adult Stem Cells in Skin In skin, different types of stem cells have been found: TypePlace Epidermal skin stem cellsBasal layer of the epidermis Hair bulge stem cellsHair follicle

17 © Mibelle Biochemistry, Switzerland 2010 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

18 © Mibelle Biochemistry, Switzerland 2010 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

19 © Mibelle Biochemistry, Switzerland 2010 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

20 © Mibelle Biochemistry, Switzerland 2010 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

21 © Mibelle Biochemistry, Switzerland 2010 PhytoCellTec TM Malus Domestica Provides two Different Modes of Activity 1. Use of plant stem cells to protect skin stem cells The 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

22 © Mibelle Biochemistry, Switzerland 2010 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

23 © Mibelle Biochemistry, Switzerland 2010 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 + apple stem cell extract Incubation Determination of CFE

24 © Mibelle Biochemistry, Switzerland % Result Number of active and healthy stem cells is increased compared to untreated cultures S-234 Increase of CFE by PhytoCellTec TM Malus Domestica

25 © Mibelle Biochemistry, Switzerland 2010 Result PhytoCellTec apple stem cell extract enhanced CFE up to 92% compared to the control. Maintenance of the stem cell vitality of epidermal stem cells was improved.

31 © Mibelle Biochemistry, Switzerland 2010 Capacity to Form 3D Epidermis Study design Comparison of 3D epidermis formed by early passage (young) and by late passage (old) epidermal progenitor cells. Test substance without test substance (control) 0.01% PhytoCellTec TM Malus Domestica S-244

32 © Mibelle Biochemistry, Switzerland 2010 Old cells (P14) (control) Old cells (P14) + PhytoCellTec MD No cell growth Day 14Day 21Day 28 Young cells (P5) (control) S-244

33 © Mibelle Biochemistry, Switzerland 2010 Epidermal progenitor (stem) cells of late passage (P14) loose the capacity to form a 3D epidermis. But when these cells are cultured with PhytoCellTec TM Malus Domestica, they retain the capacity to form a 3D epidermis similar to early passage progenitor cells. PhytoCellTec TM 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. Result
