StemCells


Most cells in the body have a specific
function in particular organs, such as the
liver, skin or brain. Stem cells are
relatively undifferentiated and still have the
ability to develop into different types of
cells to exert different functions.
A stem cell's most notable characteristic is
its ability to reproduce a completely new,
normal, and even younger cell. As a result,
people can use their own or someone else’s
stem cells, or stem cell-derived tissues or
organs, to replace ill or aging tissues or
organs. This permits treatment of a wide
range of diseases and injuries, many of
which cannot be treated with traditional
medical method

Besides reproducing new cells and
providing cell replacement, an equally
important function of the stem cells is to
provide the body with cell factors to help to
encourage the following functions:
1. Immune regulation
2. Reducing cell death
3. Stimulation the differentiation of the
patient’s own stem cells
4. Neo-angiogenesis (the growth of
blood vessels resulting in increased
blood flow to damaged areas)
5. Reducing scarring
6. Improving the effective conduction of
intercellular electrical signals and
transduction
