Expansion of functional personalized cells with specific transgene combinations.

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.

Generation and characterization of two immortalized human osteoblastic cell lines useful for epigenetic studies.

Different model systems using osteoblastic cell lines have been developed to help understand the process of bone formation. Here, we report the establishment of two human osteoblastic cell lines obtained from primary cultures upon transduction of immortalizing genes. The resulting cell lines had no major differences to their parental lines in their gene expression profiles.

Rapid establishment of G-protein-coupled receptor-expressing cell lines by site-specific integration.

The establishment of mammalian cell lines reliably expressing G-protein-coupled receptors (GPCRs) can be a tedious and often time-consuming process. A strategy has been developed to allow the rapid production of such cell lines. The first step of this approach was the generation of a specialized master cell line, characterized by optimized stable expression of a membrane-bound reporter protein.
