Project description:Highly purified subpopulations of primitive bipotent and committed luminal progenitor cells as well as mature luminal and myoepithelial cells from normal human mammary tissue were isolated and compared their transcriptomes obtained using the Affymetrix GeneChip Human X3P Array. Experiment Overall Design: 12 Afffymetrix array hybridizations were performed on RNA samples extracted from highly purified subpopulations of primitive bipotent and committed luminal progenitor cells as well as mature luminal and myoepithelial cells isolate from 3 different normal human mammary tissue.

Project description:Currently, much effort is directed to the development of new cell sources for clinical therapy using cell fate conversion approaches by small molecules. Direct lineage reprogramming to a progenitor state has been reported in terminally differentiated rodent hepatocytes, yet remains a challenge in human hepatocytes. Human hepatocytes were isolated from healthy and diseased donor livers and reprogrammed into progenitor cells by two small molecules, A83-01 and CHIR99021 (AC), in the presence of EGF and HGF. The stemness properties of human chemically derived hepatic progenitors (hCdHs) were tested by standard in vitro and in vivo assays and transcriptome profiling. We developed a robust culture system for generating hCdHs with therapeutic potential. The use of HGF proved to be an essential determinant of fate conversion process. Based on functional evidence, activation of HGF/MET signal transduction system collaborated with A83-01 and CHIR99021 to allow a rapid expansion of progenitor cells through activation of ERK pathway. hCdHs expressed hepatic progenitor marker genes and proteins, and could self-renew for at least 10 passages while retaining normal karyotype and potential to differentiate into functional hepatocytes and biliary epithelial cells in vitro. RNASeq gene expression profiling confirmed transcriptional reprogramming of hCdHs toward a progenitor state and suppression of mature hepatocyte transcripts. Upon intrasplenic transplantation into immunocompromised mice with acute liver injury, hCdHs effectively repopulated damaged parenchyma. Our study is a first report of successful reprogramming of human hepatocytes to a population of proliferating bipotent cells with regenerative potential. hCdHs may provide a nove tool that permits expansion and genetic manipulation of patient-specific progenitors to study regeneration and repair of diseased liver.

Project description:PURPOSE: To provide a detailed gene expression profile of the normal postnatal mouse cornea. METHODS: Serial analysis of gene expression (SAGE) was performed on postnatal day (PN)9 and adult mouse (6 week) total corneas. The expression of selected genes was analyzed by in situ hybridization. RESULTS: A total of 64,272 PN9 and 62,206 adult tags were sequenced. Mouse corneal transcriptomes are composed of at least 19,544 and 18,509 unique mRNAs, respectively. One third of the unique tags were expressed at both stages, whereas a third was identified exclusively in PN9 or adult corneas. Three hundred thirty-four PN9 and 339 adult tags were enriched more than fivefold over other published nonocular libraries. Abundant transcripts were associated with metabolic functions, redox activities, and barrier integrity. Three members of the Ly-6/uPAR family whose functions are unknown in the cornea constitute more than 1% of the total mRNA. Aquaporin 5, epithelial membrane protein and glutathione-S-transferase (GST) omega-1, and GST alpha-4 mRNAs were preferentially expressed in distinct corneal epithelial layers, providing new markers for stratification. More than 200 tags were differentially expressed, of which 25 mediate transcription. CONCLUSIONS: In addition to providing a detailed profile of expressed genes in the PN9 and mature mouse cornea, the present SAGE data demonstrate dynamic changes in gene expression after eye opening and provide new probes for exploring corneal epithelial cell stratification, development, and function and for exploring the intricate relationship between programmed and environmentally induced gene expression in the cornea.
