Resistance of oral squamous cell carcinomas (OSCC) to conventional chemotherapy or radiation therapy might be due to cancer stem cells (CSCs). The development of novel anticancer drugs requires a simple method for the enrichment of CSCs. CSCs can be enriched from OSCC cell lines, for example, after cultivation in serum-free cell culture medium (SFM). In our(More)
Mouse embryonic endothelial progenitor cells (eEPCs) acquire a mature phenotype after treatment with cyclic adenosine monophosphate (cAMP), suggesting an involvement of Raf serine/threonine kinases in the differentiation process. To test this idea, we investigated the role of B-Raf and C-Raf in proliferation and differentiation of eEPCs by expressing fusion(More)
At present, systemic treatment is not generally recommended for advanced biliary tract and gall bladder carcinomas. In particular cases, however, it may be justified to consider systemic chemotherapy treatment. In four cases we investigated the efficacy of palliative systemic treatment in metastatic biliary tract and gall bladder adenocarcinomas. Similar to(More)
