Stem cells intro

1. STEM CELLS
Stem cells have the remarkable
ability to "differentiate" into any
other type of cell in the body.

2. Introduction
• Our life begins from a single cell.
• A single nondescript cell with a
giant nucleus, cytoplasm, and a
cell membrane, goes on to
replicate and create every cell in
our body.
• This single cell contains within it
the entire genetic code i.e.
necessary to produce everything
that ultimately defines each and
every specialized cell type in the
body.

3. TYPES
These cells have ability to become
anything from a complete human
being to any type of tissue cell.
These cells are derived from inner
cell mass of blastocyst. & can
reproduce a number of tissue and
cells.
The more specialized cells found in adults
and children, replenishes skin cells, blood
cells throughout life.

6. Working with Stem Cells.
In Adults
Extract
cells
•In Adults the Stem cell
Reservoir is Bone marrow,
fat cells or Blood.
Grow or
Replicate
•Culturing of the
Extracted Cells.
Inject to
defect
area
•Differ into Blood
cells, muscle cells,
etc.
In Foetus
Extract
cells
•In Foetus, stem cells obtained
from inner layer of Blastocyst,
from placenta, etc.
Grow or
Replicate
•Culturing of the
Extracted Cells.
Inject to
defect
area
•Differ into Blood
cells, muscle
cells, etc.

8. Why don't we live forever?
• If we have cells with regenerative capacity
then why don’t we live forever?, why we
get aged, why capability of stem cells
decrease upon aging.?
• We deplete our reserves of stem cells
during the course of our lives.
• Our stem cells undergo various
'epigenetic' changes (insertions, deletions,
mutations) over the course of life, making
