Our StoryHow VitaCyte Began
VitaCyte’s co-founders, Bob McCarthy and Francis Dwulet, were key contributors to the development of the first commercial, purified collagenase-protease enzyme mixture used to prepare cells for subsequent transplantation. This improved tissue dissociation enzyme reagent contributed to success of the “Edmonton Protocol,” the first report of successful treatment of adult patients with Type 1 Diabetes where 7 of 7 patients were “insulin independent” one year after islet transplantation. Prior to the introduction of this purified enzyme reagent, most laboratories performing this clinical research procedure were spending significant amounts of time qualifying collagenase lots for their effectiveness to isolate human islets. Once a lot was selected, the lot qualification procedure was repeated within a year, often because of the instability of the enzymes on storage.

Published Standards for Ancillary Materials
Andrew G. Breite Two published Standards on ancillary materials (AMs) are the US Pharmacopeia (USP) <1043> and ISO 20399 International Standard. The ISO standard defines AMs as "materials that come in contact with the cellular therapeutic product during cell...
Why the Adoption of Ancillary Material Standards is Important for Cell Therapy
Bob McCarthy Windermere's "Buying Hierarchy" model categorizes the life cycle of a product into four categories: functionality, reliability, convenience, and price.(1) At the product launch, the customer asks, "Is it doing what it is supposed to do?"...
