Zusammenfassung
Hepatic stellate cells (HSC) are liver-resident mesenchymal stem cells with progenitor characteristics. HSCs are activated during liver injury and are involved in pivotal processes e.g. liver development, immunoregulation, regeneration and also fibrosis [1,2]. To date, several controversial studies reported the candidate pathways that regulate the plasticity of HSC towards distinct physiological and pathophysiological processes. Here we analyzed the expressional changes and activity of small GTPases of the RAS family, and investigated the signaling networks of quiescent HSC versus activated HSC. For the first ti…
