Intraductal tubulopapillary neoplasms (ITPNs) are composed of tubulopapillary glands with high-grade dysplasia in the pancreatic duct. Intraductal papillary mucinous neoplasms of the gastric type,(More)
To test whether yeast artificial chromosomes (YACs) can be used in the investigation of mammalian development, we analyzed the phenotypes of transgenic mice carrying two types of beta-globin locus(More)
BACKGROUND There are no established guidelines for pathologic diagnosis/reporting of intraductal papillary mucinous neoplasms (IPMNs). DESIGN An international multidisciplinary group, brought(More)
Transgenic mice were generated using a purified 248-kb yeast artificial chromosome (YAC) bearing an intact 82-kb human beta-globin locus and 148 kb of flanking sequence. Seventeen of 148 F0 pups were(More)
