Don't think I know this? Pmcb is trying to pass this approach as something new. It's not. You may know this is old technology and those dr's have been working on this and publishing their data as far back as 1998 (I've found) but how many don't?? By reading pmcb pr's one could easily think pmcb has recently come up with a new approach to cell encapsulation. It hasn't. That's attorney's for ya. Word trickery at its finest. Pmcb has made no advances in CIAB. Those are just the facts.
