What's up with the rabbit penis, doc?

By | November 10, 2009, 8:57am PST

Summary: This is a proof-of-concept test for Dr. Anthony Atala, the center’s director. The concept is that cells from a reduced organ are sprayed onto a collagen matrix, then bathed with compounds that stimulate cell growth and left in kept in an environment that duplicates the temperature and chemical makeup of living tissue.

News that the Wake Forest Institute for Regenerative Medicine (yep, WFIRM) has successfully grown rabbit penises in a lab set off a media feeding frenzy.

These are fully-functioning organs. The rabbit recipients went at it like, well, rabbits.

But there is more to this story than meets the snark.

This is an important proof-of-concept test for Dr. Anthony Atala (right), the center’s director.

The concept is that cells from a reduced organ are sprayed onto a collagen matrix, then bathed with compounds that stimulate cell growth and left in kept in an environment that duplicates the temperature and chemical makeup of living tissue.

The success of the technique means Dr. Atala could also grow new noses, new ears, perhaps even new fingers that are fully compatible with, and in many cases nearly identical to, the originals. This is not a fancy “stem cell” technique but a more straightforward one with wide application.

The news comes just months after Dr. Atala formed an Alliance for Regenerative Medicine that not only includes other colleges like Stanford and Georgia Tech but corporations like Geron and Johnson & Johnson, along with venture capitalists like Kleiner Perkins.

The aim of the group is to maintain political support for research and for the technique itself, said Geron CEO Thomas Okarma in the group’s initial press release.

The apparent success of the technique may be the best advertisement of all.

Although we know what Jay Leno will say about it. “Does this mean Cher can finally become a grandmother?” Rimshot optional.

Could it apply to......
Economister 10th Nov 2009
brain and spinal cord injuries? Damaged hearts, lungs or kidneys/livers? A new finger/arm would be nice for amputees etc, but the above are far more debilitating and the victims in greater need of organ regeneration.

I believe it might

Since this work was done with organs, I extrapolated to organs. But I assume nerves could also be created. The problem is grafting them...

Interesting

Besides the obvious medical benefits from growing new tissue and organs, another thought comes to mind. Would not this technique be usable for food production? Could we grow chicken legs without the chicken? Steaks without the cow? Fillets without the fish? Cost would be an issue, but if the technique is viable, it could increase food production, free up land, and take pressure off of the oceans. This could also make colonization of space more viable.

I think it's possible by other methods

The idea of creating meat without creating animals has been conceptualized for quite a while, and a version of this might work for that.

But the actual experiment involved building a working organ on a collagen scaffold. Wrong methodology for filets. And you don't want bones in yours anyway.

Collegen, in a culinary sense, makes gravy.

Oh boy, I can just see it now

This will open up a whole new opportunities for Smilin' Bob and his ilk. Now I won't just be getting spam about pills I can pop to "enhance my member", now they'll tell me I can get a new bigger one custom grown and attached by a plastic surgeon. Enzyte? Plttht! We'll grow you your very own horse dong!

Won't solve that problem
DanaBlankenhorn 10th Nov 2009
The problem solved by scams like Enzyte isn't the size of the member, but the difficulty in executing its growth.

High blood pressure is one condition that can cause this, so if you have ED do see your doctor, not just for your sex life but for your continued life.
GUYS - YOU MIGHT HAVE TO 'SPLAIN THIS TO enny GURLS THAT
READ THIS . . . but this research project was incredibly
well planned. Over the past few years researchers have
performed similar "feats" starting with "gelatinous,
cartilaginous scaffolds" and creating portions of the
human esophagus, various animal organs (beating hearts,
lungs, etc) but nothing so creative as a rabbit dong.
Indeed, a few years back when a portion of a human
esophagus was implanted and allowed a woman from Spain to
function "normally" again, the accomplishment was
considered a miracle. (And so it was.) But to create
such a highly vascular structure as this wabbit wong so
that the rabbit uses it without hesitation - well this
accomplishment is far more miraculous. (Gurls - ask a
male or just trust me on this topic.) This "giant leap"
forward gives great hope that the next trials for humans
will "leapfrog" the simple replacement of a tuberculous-
damaged portion of a human esophagus. (And yes ? maybe
this story is more striking to me since I still remember
back when I was 10 years old - when we got this female
rabbit for to be a friend for the male rabbit we already
had. And I remember how shocked I was that the male
rabbit had "a pair" that were as large as a ten year old
human's. On that itsy bitsy body! No wonder food was
his second interest in life.)
