an islet transplant.
Yet the islet of Ulithi is perfectly situated between Hawaii, Japan, and the Philippines.
We did 66 islet transplants at Edmonton.
Well after the islet cell transplant, we can achieve the below the red line or under the red line very reliably without the risk of hypoglycemia.
a biological license for islet transplantation, allowing Medicare, Medicaid, and third party payers to potentially reimburse islet transplant in the US, which
So I mentioned islet transplants today, and stem cells tomorrow.
And the islet cells, the vary in size, from about 50 microns to 150 micrometers in size.
But the islet is sort of an organelle collection of several types.
We think that the islet needs all of those cell types in order to survive in the longer term.
So an islet in some way has a lot more potential
Initially around 5,000 islets per kilogram based on the recipient's weight.
Those are very pure islets ready for infusion.
there are islets surviving quite well, but no beta cells in that biopsy, which is from Dr. Razinia's group in University of Massachusetts.
and repair of injured islets .
So the islets have sensors on them.
But really our indications for islet transplantation have been to try to reduce this risk of hypoglycemia, reducing the risk of lows in patients
This will happen again after an islet transparent to the new cells, unless the anti-rejection drugs are given.
So there's been real progress in islet cell transplantation.
So who do we offer an islet transplant to today?
We gave two sets of islet infusions.
So we recognize today that islet transplantation, the way it is today, because patients need immunosuppression, because there is a shortage of organ
But we don't just get the islets from anywhere.
And here you can see islets surviving in that round area that used to have the little catheter on the top left there.
Now this is what we can achieve today with an islet cell transplant in the lower panel here.
Last year we did a record number of islet transplants in Edmonton.
every one of those represents over 1,500 islet isolations done by our team over the last 15 years.
What he finds in a control group with islet transplant versus conventional, or best medical care insulin therapy, is the islet transplant group has much lower hemoglobin
So this is very encouraging data to suggest that an islet or other cell transplant, or stem cell transplant in the future for diabetes,
The short one is-- do you transplant the entirety of the islet , or just the beta cells?
by the same antibodies that originally killed of the islet cells?
The cells in the pancreas that make insulin are called islets of Langerhans.
So we're looking at alternative retrievable sites to put in islets today, or stem cells potentially tomorrow.
That we're looking now to other alternative sites for infusing islets under the skin.
And so, the islets are taken out of the pancreas in that process.
We could add other products locally around the islets to protect them.
And I'll try and take you along that journey of cutting edge islet and stem cell transplant treatments in the clinic for diabetes as we move forward today.
But it's very typical of what we can achieve routinely with an islet cell transplant.
And here you can see, after the islet transplant, when the patient discontinues insulin, the blood sugar control becomes very tight, is in the normal range
We have two real major categories-- those with patients who have an islet transplant alone.
So you can see that most patients require-- in our center at least-- two islet infusions to provide sufficient mass for them
Because zinc and insulin are very closely linked Studying the zinc inside the islet , so you can see then quite clearly under the microscope.
And that has eliminated the risk of complications such as bleeding after the islet transplant So this is a very safe procedure.
And now there are 6 centers across the world that have insulin-free rates with islet cell transplant of five years, more than 50%.
Several groups have reported the ability to achieve what I showed you with two islet transplants with a single donor islet infusion.
And so the second question was-- Do you do anything to modify the islet cells prior to transplant?
And so I'm going to explain to you know how we get the islets out.
And i didn't mention, the islets have several cell populations int them.
DR. JAMES SHAPIRO: So the islets that we transplant are the collection of all the cells.
I'm going to read a little passage to you where's she gone with this group of people to this little rocky islet to try and lure out
And still I think if you can read and you can Google lots of negative reviews on islet transplantation, because I think the knowledge in this area probably
