| pubmed-article:15110608 | pubmed:abstractText | We describe a method to consistently prepare human islets for transplantation. By combining a simple collagenase digestion method and a density gradient purification system, we were able to obtain successful isolations (>/=200,000 islet equivalents, >/=50% purity) in 69% of processed glands. No reagent of animal source was used. Isolated islets were morphologically well maintained and functionally competent, with sterility confirmed in 97% of cases. Two patients were transplanted with islets prepared by this method; graft function was demonstrated for a few months. Improved simplicity and consistency, together with adequate quality of the preparations, are the main features of this isolation method. | lld:pubmed |
