FACS-Sorter mit UV-Laser
Zusammenfassung der Projektergebnisse
The FACS-Sorter with UV laser was needed to found a new cell isolation core facility for the SFB/TRR57 “organ fibrosis: from mechanisms of injury to modulation of disease” at the universities of Aachen and Bonn. In the first funding period, the major aim of this core facility was to establish procedures that allow providing researchers of the Collaborative Research Centre with healthy viable primary cells of murine and rat livers and kidneys. Using conventional isolation procedures, we have set up a logistical and methodological platform that routinely provides primary hepatic stellate cells (HSC) and hepatocytes to all projects in Aachen and Bonn upon request. Moreover, we have introduced novel innovative FACS-based sorting protocols that further allow enrichment and characterization of highly purified hepatic stellate cells from murine livers using their autofluorescence in the UV channel and negativity for hematopoietic surface markers. Other protocols were established for the isolation of immune cells from blood, liver, kidney, spleen, bone marrow and peritoneal lavage as well as standard procedures for sorting labeled cells (e.g. GFP, RFP, LacZ). Magnetic bead separation techniques were introduced for the isolation of glomerular cells from mouse kidney. The purified cells were taken as starting material by multiple researchers of the SFB/TRR 57 (P01, P04, P05, P06, P07, P08, P09, P13, P14, P17, P18) to address specific questions on fibrogenesis as outlined in the individual projects. In particular, the highly purified HSC allowed addressing sophisticated questions dealing with cell-specific expression of miRNAs and candidate genes relevant for fibrogenesis as well as studies that analyzed issues of cell-cell interactions.
