HOPE FORTHE
HOPELESS.
THE LATEST DEVELOPMENT
OF
STEM CELL RESEARCH
Stem
cells are the
original
"mother
cell"
that differentiates
into
vari-
ous
types
of
cells, enabling cloning of
new organs
for
replacement
so
that dis-
eases of the liver, blood, cornea and
even dementia,
etc.
can then
be
cured.
Within
10 years,
the cloning
of human
organs would be implemented on
a
wide scale and treatment for many dis-
eases
is no longer too fragmentary
for
cure. Cloned organs do not have rejec-
tion problems. Moreover,
if
one
day,
we
could use our stored cells harvested at
youth
to
restore
our
degenerated
organs, we
would literally
live for everl
At
the Harvard
University, USA,
scien-
tists taught 2
parrots
to
sing.
After
de-
liberately destroying
the
central nervous
system of
1
parrot, singing could
be
"re-
activated"
by
infusing
nerve cells
from
the
normal
parrot.Thus,
stem cells can
actually repair damages
of
the recipi-
ent even according to the message im-
parted so
that
normal and
previous
function could be restored. Aplastic
anaemia
(failure of
the
marrow
to
pro-
duce
red
cells)
may
also
be
cured;
so
can inborn
immuno-deficiency
states
-
born without
the cells
generating
immunity.
At
present, tissues
like
cartilage,
blood
vessels,
heart valves,
muscles, ligaments, cornea or
even
retina can be cloned and clinical use
is
being tried.
