Can Embryo Cells Experience Pain? Posted: 06-25-07 10:23am
Hmmm...up for debate? Scientists say NO:
embryos lack sensory organs or tissues.

From what I understand the “pain
system” ( spino- thalamic ) begins to
develop at 7 weeks. As it develops into
more weeks the pain system would get
stronger. But to say there is no pain at 7
weeks when it is in the first development
stage would be hard to determine. Or prove
unless you where the actual embryo and
could say.. So I think yes. If the spino
thalamic is developing at 7 weeks. I would
say there could be a certain amount of
pain.

I don't think that embryos being used for
stem cells are at 7 weeks gestation, are
they? I really don't know.

That's a good question Silly. I tried to
find a site that told at what stage stem
cells are taken and I can not find at what
gestation time they are taken.
I will keep looking. If anymore finds the
answer, please post.

After about five days of development, the
embryo consists of a ball of 50 to 100
cells called a blastocyst. Embryonic stem
cells are derived from an inner cell mass
within the blastocyst. The blastocyst is
no bigger than a grain of sand and its
cells have no fixed destiny. There is no
trace of any structure such as a nervous
system which would, for example, produce
sensations of pain.
Sounds like the cells are taken at a very
early stage. Knowing that, I would say
there is no pain envolved. But From what I
have read the embyro dies. Is this true?

I should imagine so and even if the
procedure didn't kill it then it would be
destroyed afterwards because embryos for
implantation are not used.

Embryo's used in ESCR can not be
experimented upon after 16 days.
embryos are not "taken" but created
especially.
embryos are kept frozen for upto a year
after experimentation and then
destroyed(killed)
to our understanding of the embryo
regarding what makes more developed human
beings feel pain the embryo is lacking the
ability - however we simply do not know
beyond that understanding if pain can be
felt via some other unknown means.

Scientists do know who can or cannot feel
pain to a much greater degree of certainty
than it would appear is being discussed
here.
The way scientists have learned over the
years what parts of the brain do is by
people that have had traumatic brain
injury. When a person comes to the
hospital with a certain part of his/her
brain injured, the scientists take note as
to which functions the person can no
longer do.
For example, has the person lost their
short term memory? So, after hundreds of
cases of the same part of the brain being
injured and people losing their short term
memory, scientists concluded that brain
part x (the part injured in all of the
patients) was involved/needed for short
term memory.
(Short term memory is, for example, what
you use when trying to remember a phone
number.)
This is also how they know what brain
parts are needed to feel pain. A fetus
cannot feel/experience pain until very,
very late in development, when the brain
is almost completely formed, in the third
trimester, at about 26 weeks.

The problem is defining pain. Pain is a
signal sent to the brain that some organs
are not working properly or are damaged.
The signal is than felt as pain by the
consciousness.
