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

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.
Singh and Bhalla, TRENDS in Plant Science, Vol.11, 2006
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

•
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
