Functional remodeling of primary and immortalized progenitor and intermediate cells

ABSTRACT: Tissue remodeling or regeneration is believed to initiate from organ-specific stem and/or progenitor cells. We report here the establishment of two spontaneously immortalized adult human benign prostate epithelial cell lines, NHPrE1 and BHPrE1. NHPrE1CD133(++)/CD44(++)/OCT4(++)/CK14(+++) was characterized as a putative progenitor cell, and BHPrE1CD133(+)/CD44(+)/OCT4(+)/CK14(++) as a putative intermediate cell. aCGH analysis demonstrated a largely intact diploid karyotype with DNA amplification of PTEN in NHPrE1 or Beta-Catenin in BHPrE1 cells, respectively. A tissue recombination-xenografting model was utilized to compare remodeling of human prostatic tissues in vivo by the NHPrE1 and BHPrE1 cell lines and their parental primary cells. A series of tissue recombinants, made by mixing diffe
