Transcript of Stem Cells

The Scientists
The Public
There are plenty of stem
cell lines available for
scientific research.
There is an insufficient number
of stem cell lines available for
research, and the lines that
do exist are practically useless.
'Adult' stem cells are
a viable replacement for
embryonic stem cells.
Once the restrictions on embryonic stem cells has been lifted and scientists are able to use them for research, there will be cures for numerous medical problems.
There are many areas that scientists
would like to explore with stem cell research that can only be done with embryonic stem cells, not 'adult'.
Though there will be a lot of
progress when restrictions on
embryonic stem cells are lifted,
it will be atleast 3-5 years before
any significant results are seen
and most likely much longer before
cures to diseases are found.
STEM CELLS
What are Stem Cells??
internal repair system
unspecialized vs. specialized
replication

differentiate into blood cells
bone marrow transplant to cure immunodeficiency disease

it's taking a life
adult stem cells

Adult stem cells in organ/tissue creation.
The 4 Goals: organs/tissues, diseases/conditions, medications, treatments/therapies
2001: Bush. Derivation vs. Line
Funding
Only 22 that are old, contaminated, and not diverse.
2009: Obama - Guidelines on Human Stem Cell Research
Part of the controversy.
A 'fix all'.
Not a 'magic cure', and definitely not quick.
Thanks for listening! Bye!
