Thank you, again, for your professional and well researched response.
I re-reviewed most of the abstracts of their researchers cited in the
biliography and stand by my conclusion that they have published nothing in
regards to tissue regeneration. Their product, Dermagraft-TC, apparently is
headed toward FDA approval and it could be of help to burm victims if their
process turns out to be cost effective. Their research papers reflect these
efforts and I hope they're successful.
The question they don't appear to answer in any of their research papers is
how do they get these human fibroblasts to live beyond their "Hayflick
Limit"? If human cells, dermal, epidermal or otherwise could just grow on a
matrix of synthetic fibers this would have been done years ago.
Other "published" research seems to suggest that transforming growth factor
beta2 has an effect on cellular communication and age related genetic
expression. Some of these effects have the result of neo-natal skin cells
failing to differentiate and continuing to reproduce for an extended period
during this stage.
Advanced Tissue Sciences, Genzyme and a number of other companies are
expanding on these and other results to develop their "propriatary" processes
to develop a patentable end product. By keeping the results of this
underlying research secret, these companies are hindering the research into
life-extension.
I may be "demonizing" these companies but they are "killing" us! Each day
they refuse to share information on processes that have a direct relation to
cellular aging is a days delay in the research into longevity. How many days
do you have left?
