Micromanipulator developed to deliver stem cell

Someone shared the following links which said the micromanipulator tool can deliver stem cells into the inner ear in the future

They brighten my otherwise dull day today; I am today feeling (I feel it from time to time and not always) a bit imbalance on my right side because my left ear's balancing mechanism has probably been knocked out by virus, mini-stroke or whatever which took out my hearing and caused T too!

Genvec CEO shared in Feb 2010 that Atoh1 can restore all hearing freq

It is a very wonderful report. For eg, it tells us that Atoh1 is unlikely to cause cancer (1 of the major worries for this novel gene therapy using Atoh1 to restore hearing). On the contrary, it suppress cancer !

MIT is developing inner ear drug delivery device

Harvard Medical School and MIT seem to be developing a inner ear drug delivery device. See link below.

I surmise from the materials that they must have some sort of effective drug up their sleeve already. It is some sort of solid dry drug, that need to be continuously delivered (controlled by a microprocessor) over years into the inner ear to be effective, something to do with the Atoh1 gene which Genvec is partnering Novartis to co-develop with a war chest of over US$200 million.

And it follows from the above (eg that it need to be continuously delivered over years)that it is not only for repairing damaged hair cells in 10-days old patients only (see my other report or 2nd link below) :

Atoh1 repairs hair cell damaged up to 10-days ie for 10-days old patients

This report says Atoh1 repairs 10-days old patients' hair cells.

One may then ask whether it is the end of the hope that Atoh1 (which in Jan 2010 Genvec is reportedly co-developing with pharma giant Novartis with a war chest of over US$200 million) can cure deafness which has occurred for some time.

I think not.

For one, the same report seems to suggest it is an additional function for Atoh1, on top of regenerative qualities.

Also I found these materials from some good soul that Harvard Medical School and MIT seem to be developing an inner ear drug delivery device. See link below.

Patent for Atoh1/Math1 gene therapy filed - the end is near!

Some good person has alerted me to this very informative and good news that a patent for the Atoh1/Math1 gene therapy has been filed.

It was filed in Feb 08, which is only good news because it means much have been done since.

I expect a real cure is really coming, fast. The end is near !!

Isolation and culture of the cochlea from neonatal mice and proof of Atoh1/Math1 healing agent capability

This link describes a method for the isolation and culture of the organ of Corti from neonatal mice. It also proved Atoh1/Math1 healing agent is able to re-generate inner ear hearing hair cells.
