干细胞培养关键因子——HGF - 知乎 - 知乎专栏
HGF首先以无活性的单链蛋白(HGF/SF)形式分泌,经肝细胞生长因子激活因子切割成成熟的异二聚体HGF,机体内HGFA可激活HGF/SF前体,使之从单链前体变成双链活性形式,是调节细胞外HGF/ SF活性的关键步骤。 此外,HGF在促进肝细胞再生的同时参与正常组织的损伤后修复、细胞的运动以及肿瘤的形成、浸润和转移、分化以及肿瘤血管行程中发挥重要的作用。 HGF存在于动物和人体内多种组织和细胞中,主要来源于肝脏 (肝窦内表面的吞噬细胞)、内皮细胞、成纤维 …

The new phase of HgF 2 at high pressure - IOPscience
2013年5月15日 · We here report a stabilization HgF 2 high-pressure phase predicted by the density functional structural searches, which adopts the Pnma symmetric structure (12 atoms/cell, α -PbCl 2 –type, or cotunnite). The phase transition from the ambient conditions phase Fm -3 m (phase I) to the Pnma phase (phase II) was confirmed at 4.7 GPa.
