Snorting Brain Stem Cells is a Viable Implant Option

[quote]When surgeons need to deliver a payload directly to a patient's brain, it usually involves a rather invasive procedure that opens the skull and leaves the delicate grey matter inside inflamed. But researchers at the University of Minnesota have discovered that patients with brain maladies can simply snort stem cells through the nose and directly to the brain, offering an effective and fast alternative to complicated neuro-surgical procedures.
The researchers discovered that when suspended in fluid and snorted, stem cells migrate quickly to the brain, arriving within an hour in most cases. Researchers initially tested the procedure on mice, having them sniff adult rat stem cells suspended in solution. An hour later, the inhaled stem cells were visible within the brain. Testing a second time using stem cells from a human tumor, the cells again migrated straight to the brain, also within an hour's time.
The stem cells likely reach the brain by way of the olfactory nerves, which give us our sense of smell. Fluid-filled spaces surrounding blood vessels that pass from the nose to the brain are also a likely conduit. Only 584 of 300,000 cells reached the brain initially, but researchers found that when they added an enzyme called hyaluronidase that makes connective tissue more permeable, the number of cells that reached the brain nearly tripled.
The convenience of the procedure is a boon to neurosurgeons, but there are added advantages over surgical implanting that go beyond the ease of execution. For one, if a certain treatment doesn't take hold, doctors can easily try again without having to wait for the patient to recover from surgery (and without then conducting a second tricky surgery). The procedure also has vast implications for many neurological diseases like Alzheimer's, Huntington's and Parkinson's, that currently enjoy few treatment options.
There are no approved stem-cell therapies for brain disorders currently, but intra-nasal cell delivery could help persuade the FDA that such procedures can be performed safely. As such, the next step for researchers is to ensure intra-nasal stem cell technology doesn't cause any inflammation or infection of brain tissue, or precipitate any autoimmune response. Even so, the right cocktail of stem cells and anti-inflammatories or antibiotics could mean the next generation of nuero-treatments could be administered as easily as over-the-counter nasal decongestants.[/quote]
I can see this being used alot
Minnesota represent.
That's interesting.
I can see this as a new form of addiction. :v:
I don't want a brain growing out of my nose though

Oh yeah.
Also, cool I guess. You'd think things like this would be discovered at Mayo Clinic.
Wait, how do the cells know to go to the brain?

because god told them to, duh
we should have stem cell cocaine
no i mean seriously, have them think it's a placebo as their brain begins to regrow(is that possible?) back to before their addiction.
Lots of crazy stuff happening at the U of M lately...
Snorting dead fetuses eh?

All the cool kids with brain damage do it.
Kill someone and snort their brain.
I like it.

Not how it works.

God damn sploicers.
I don't even have brain damage and I feel like doing this.
Drugs that make you smarter! :downs:

Like anybody actually cares!
Neat way to deliver the stem cells, but how do you get them to do what you want them to do once they're there.
Reminds me of the novel Dune.

Minnesota has the best healthcare n shit
Nice doctors, clean hospitals, good service, etc...
