What are stem cells?
• Unprogrammed cell • Differentiate into cells with specific function • Advantage – Regenerative medicine • Stimulate healing • Extended healthy life span

Stem cells
• Self-renewal • Generate differentiated cells General features of a stem-cell niche.
Sablowski,TRENDS in Cell Biology, Vol.14,2004
Animal and Human Stem Cells • Embryonic stem cells – Pluripotent differentiation potential • Adult stem cells – To maintain and repair tissue • The same DNA and the same gene – Signal inside the cell – epigenetic signals tag DNA – Surrounding histone protein: regulate gene
Plant stem cells
• Shoot apical meristem • Root apical meristem – Epigenetic – Totipotent http :// www .

Meristems • specialized proliferation tissue – the growing tip of roots and shoots – generate new cells Dinneny and Benfey, Cell 132, 2008
Root meristem
• Quiescent center cells (4 cells) • Single layer of stem cells • Daughter cell (2 cells) – Cell renewal – Formation of mature tissue Dinneny and Benfey, Cell 132, 2008
Positioning the Root Stem Cell Niche Dinneny and Benfey, Cell 132, 2008
Shoot meristem
• Organizing center – Several layers of cells – Plant growth hormone • Promote cell cycle activity • Promote growth • Shoot identity Dinneny and Benfey, Cell 132 , 2008
Shoot apical meristem Branch Leaves Flower
Plant shoot apical meristem (SAM) and root apical meristem (RAM) SC niches. The organizing-centre cells provide signals for maintenance of the overlying SCs, which are surrounded by a TA population of cells in the meristem peripheral zone (PZ). In the RAM, the quiescent centre (QC) is the source of SC maintenance signals.

The role of stem cells in the skin • Epidermis – stratified epithelium – interfollicular epidermis • Hair follicles • Sebaceous glands
The hair bulge contains multipotent stem cells that contribute to the lineages of the epidermis, the sebaceous gland and the hair follicle Schmid et al., SÖFW-Journal | 134 | 5-2008
Epidermal stem cell generates transit amplifying cells that differentiate to form the stratified layers Schmid et al., SÖFW-Journal | 134 | 5-2008

Plant stem cell and their propagation in culture • Sterile condition • Standardized condition
Plant stem cell products
• Centella asiatica cell culture 20% • Echinacea angustifolia cell culture 20% • Buddleja davidii cell culture 20% • Leontopodium alpinum cell culture 20% • Malus domestica fruit cell culture extract
Claims
• Stimulate human stem cell growth • Maintains the self renewal capacity of stem cells • Increases longevity of human skin stem cells • Delays senescence of essential cells • Combat chronological aging • Preserve the youthful look and the vitality of skin • neutralize, often reversing, the effects of aging on the skin • protect stem cells from death due to UV overexposure • protects human skin stem cells from stress, thus decreasing wrinkles and producing younger, fresher looking skin .
