First Embryonic Stem Cell Clinical Trial Imminent

An anonymous reader writes "California-based Geron has announced that the first embryonic stem cell trial may be in the not-so-distant future. Tom Okarma, Geron's CEO, recently announced that the company will be seeking permission from the FDA to begin clinical trials. From the article: 'Geron's plan is to treat people that have acute spinal injuries with oligodendrocyte progenitor cells grown from human ESCs. Oligodendrocyte cells support neurons in the brain and spine by sheathing them in myelin, a fat that helps neurons to transmit signals.'"

      Well, there are two problems with that as presented in the vision of the future of Larry Niven's Gil Hamilton universe (not so hot writing, but good futurism).

      The first is that people would be more likely to take organs from criminals, since they at least can be seen as culpable. This is reputably already popular in China, where if you commit a heinous crime people are going to have no sympathy for you whatsoever. If you're creating human life for the mere extraction of organs, then said human life has an aura of innocence Tabout, and so the matter will weigh heavily on society's hearts. The consequence of taking organs from criminals, however, may be that the death penalty becomes proscribed for all kinds of minor infractions, from driving under the influence to vandalism.

      The second problem is that I don't foresee the need for organs lasting so long that we'd get to the point of creating an entire human being just for organs. New breakthroughs in alloplasty ("gadgets instead of organs") might free us from the problem of donations forever.

    Ethanol does have an effect on transmission (specifically it reduces excitability and increases the effectiveness of GABA, an inhibitory neurotransmitter), but those are effects on action potential generation. Myelination from oligodendrocytes just increases the ability of an already generated action potential to reach the end of the axon and cause synaptic activity. So the oligodendrocytes' effect is sort of like plugging holes in a leaking pipe, whereas the effect of alcohol is more like decreasing the chance that water will actually enter the pipe in the first place. Which is to say: alcohol's work is already done before the myelination comes into play, so increasing the latter won't much affect the former.

Genentech immediately went back to the drawing board and developed Lucentis which is a smaller molecule that can more easily penetrate the retinal membrane.
