Abstract:In vitro transformation of rat urothelial cells is a multi-step process. We have used cell fusion to analyse the role of recessive events during in vitro progression of an immortal urothelial cell line. Somatic cell hybrids were made between the transformed cell line RM2T and a series of immortal urothelial cell lines, including the progenitor line RM2AD, from which RM2T was isolated. The ability to produce colonies in soft agar (anchorage independence) was used as an in vitro marker of transformation, and a s… Show more
