After partial hepatectomy and some chemicals induced acute liver injury, existing hepatocytes can expand to repair the liver function. While adult liver stem/progenitor cells(LPCs) are evoked and differentiate into functional hepatocytes and cholangiocytes to compensate the damaged liver once hepatocyte proliferation is severely impaired. A number of evidences suggest that adjacent hepatic stellate cells(HSCs) or invading leukocytes may be involved in LPCs directed regeneration through governning two major events including fibrogenic and inflammatory responses respectively or simultaneously. As such, a microenvironment(or "niche") composed of different cell sources or factors presents diversity, which eventually mediates LPCs response to biliary or hepatocellular regeneration. This mini review aims at summarizing the latest development on the roles of HSCs, macrophages and lymphocytes as well as corresponding signaling pathways in liver progenitor cells mediated biliary and hepatocellular regeneration, and discussing therapeutic potential of liver progenitor cells in hepatic diseases.展开更多

Despite of the efforts of the negotiators and the support of the US administration, the goal of reaching a final status agreement between the two sides once again could not be achieved. Considering the complexity of the issues, the failure did not surprise most experts who follow the Israeli-Palestinian conflict. The reasons are many, but no doubt, the main issue is the distrust between the two sides. The Palestinians, on the one hand, believe that Israel does not want to leave the West Bank and is pursuing the unilateral security policies implemented by Ariel Sharon and his successors after the Camp David talks in 2000. Israel, on the other hand, believes there is no partner on the Palestinian side, with its leadership divided and with Hamas showing no sign of recognizing Israel＇s very existence. Due to the distrust between them, the two parties are heavily dependent on US mediation. Accordingly, both sides restarted negotiations under pressure from the Barack Obama administration half heartedly. In addition to existing problems, Turkey＇s involvement in the conflict by challenging the Gaza embargo and by supporting Palestinians at the expense of Israel in the international arena jeopardized American efforts. So, the failure of the talks was no surprise for many and no doubt it will have considerable consequences for both sides, as the July War in Gaza proves. This article focuses on the limits of American mediation for building trust between the sides, the micro-reasons of the failure of the talks, the possible consequences of this failure, and Turkey＇s Palestinian policy as a further complicating factor.展开更多
