Hi Patricia, Exten is also well thought of over at wwwDOTstemcellsclubDOTcom EXTI is followed closely by a highly educated group on stem cells and the like. I too believe in the MultiCell products and the abilities of those products to save the Pharma's time and money. The timing of the product to the market place could not have been better either. 2004 will be breath-taking imo.
