  Background: To generate an in vitro system of the dermal epithelial-mesenchymal interaction we co‑cultured HaCaT (keratinocytes) and HEPM (embryonic mesenchyme). This model allowed a local disjunction with preserved cell-cell communication. Methods: For the analysis of different protein expression patterns between co- and pure-cultured HaCaTs we performed 2D-electrophoresis and mass spectrometry. Afterwards the mass spectromertically identified protein 14-3- 3σ was silenced by siRNA in HaCaT cells. Results: We analyzed 28 spots and found 17 different expressed mainly metabolic and cytoskeletal proteins. Interestingly, stratifin (14-3-3σ), maspin and Profilin-1 (PFN1) were up-regulated, whereas Peroxiredoxin-5 (PRDX5), PDZ-and-LIM-domain-protein-1 (CLIM1) and Annexin A1 (AN.. View More»
