Project description:The aim of this study was to compare the most common immortalized cardiac cell lines (human: AC16, rat: H9C2, mouse: HL-1) to primary cultures (neonatal rat or mouse cardiomyocytes, and human induced pluripotent stem cells) and left ventricular tissues from the corresponding species. To characterize cardiac cell lines, cardiac cell lines were seeded onto plates, and their differentiation towards a more cardiac phenotype was induced on the basis of most commonly used protocols in literature. The cells were harvested either in stage of proliferation or differentiation, and left ventricular tissue from each corresponding species, and isolated neonatal primary cardiac myocytes (for mouse and rat) or human induced pluripotent stem cells were applied as references for comparison. Transcriptomic analysis was performed on all samples. Generally, the mRNA expression pattern of cardiac markers in the cell lines showed significant differences compared to corresponding tissue or primary cultures. mRNA profile of cell lines indicates poor cardiac characteristics regardless the differentiation protocol used. Limitations of these cell lines should be taken into account when these cells are used as in vitro platforms to model cardiomyocytes and cardiovascular diseases.

Project description:Müller cells (MCs) play a crucial role in the retina, and cultured MC lines are an important tool with which to study MC function. Transformed MC lines have been widely used; however, the transformation process can also lead to unwanted changes compared to the primary cells from which they were derived. A monoclonal spontaneously immortalized rat Müller cell line, SIRMu-1, was derived from primary rat MCs and characterized by RNA-sequencing (in addition to immunofluorescence and western blotting) in comparison to primary MCs and the SV40-immortalized MC line, rMC-1.

Project description:Fundamental research and drug development for personalized medicine necessitates cell cultures from defined genetic backgrounds. However, providing sufficient numbers of authentic cells from individuals poses a challenge. Here, we present a new strategy for rapid cell expansion that overcomes current limitations. Using a small gene library, we expanded primary cells from different tissues, donors and species. Cell type specific regimens that allow the reproducible creation of cell lines were identified. In depth characterization of a series of endothelial and hepatocytic cell lines confirmed phenotypic stability and functionality. Applying this technology enables rapid, efficient and reliable production of unlimited numbers of personalized cells. As such, these cell systems support mechanistic studies, epidemiological research and tailored drug development. In these experiments primary HUVEC were compared to immortalized HUVEC with respect to their global gene expression pattern.
