The trial you linked (as well as the two other registered trials using mesenchymal stem cells for Ankylosing Spondylitis that I found) are using allogeneic (donor) MSCs. I've been in MSC research/development for 17 years and now c

Ponzi schemes are terrible. Many ICOs aren't much more. However, blockchain enables digital scarcity. That's an interesting piece of technology right there. Using it as a state-machine is a very interesting application of it. IMHO

TBH part of what makes me so bullish on Ethereum is how much of an emotional reaction it produces, both for and against the technology, all the while it continues to gain mindshare and utility.

I feel the same. I can't fathom the lack of imagination, and IMHO that's what it is. I've loaded Lemonade Stand on an audio cassette, and with the same fingers, I now type this on a black wafer on a plane.

Outside of the body in culture? They do seem to age if grown for very long periods of time. This is why we cryopreserve them, it essentially freezes them in time.

In most cases, you cannot. Cells that are not your own are cleared from the body or rejected in a short time.

We collect 60mL, less than 10% of what may be drawn in a bone marrow donation by this method, of which there are no known deleterious effects. Our physicians suggest you take it easy for a day or so, but aside from a tender spot, recovery i

The discomfort is difficult to describe. I best describe it as a cramp. We believe that the negative pressure is in part to blame, and we have filed IP on a possible solution.

We aren't propagating at intervals currently. However, it's something that could be done; batch samples could be set aside for that purpose alone, also, one control sample could be divided and tested every 5 years. It's an in

If expanded over many passages in culture, the cells can degrade, much like they do due to age. For this reason, it is advantageous to start with sufficient numbers (thousands), rather than a few cells. However, as mentioned, we have improv

Thanks! We do perform QA on samples post-freeze process. We are working on some uses of these cells for rejuvenation purposes. We will be sharing specifics on that in the coming months. Here are a couple of posts that I made about one exper

We collect 60mL. There are normally about 10-15M nucleated cells recovered per mL of bone marrow. Stem cell counts are typically 0.01% of this (MSCs are about 1000/mL). We bank the cells in multiple chambers (3 larger ones, 5-6 smaller

A bone marrow biopsy is much more painful than an aspiration, which is what our physicians do. There is variability, but my own experience was a fleeting cramp (3 out of 10), that lasted about 15 seconds. I have been many of our collections
