Effect of musk soluble components on the growth, the differentiation and the transfection efficiency of rat neural stem cells (NSC) in vitro / 中国应用生理学杂志

<p><b>AIM</b>To investigate the effect of musk soluble components on the growth, the differentiation and the transfection efficiency of rat neural stem cell (NSC) in vitro.</p><p><b>METHODS</b>The growth and the differentiation of rat NSC were observed when musk soluble components were added into the culture medium of NSC. Meanwhile, the pEGFP-C1, which expressed the enhanced GFP protein, was transfected into the NSC by method of electro- transfection.</p><p><b>RESULTS</b>When NSC was treated with musk soluble components, the neurites were outgrowth around NSC and attached to the plate, and the neural spheres were disassociated. The glia-like cells appeared at the concentration of 0.3 per thousand. When the concentration of musk soluble components was lower than 3 per thousand, the transformative cells could recover. Furthermore, the efficiency of transfection pEGFP into NSC was remarkably increased after the treatment with musk.</p><p><b>CONCLUSION</b>After the treatment of NSC with musk soluble components, the neural spheres were disassociated, and then attached to the plate. Musk soluble components could induce NSC differentiation into glia-like cells and improve the transfection efficiency of pEGFP-C1 in vitro.</p>

Expressions of hepatocyte growth factor and its receptor protein in human thyroid neoplasms / 中华内分泌代谢杂志

The expressions of hepatocyte growth factor (HGF) and its receptor (c-Met) protein were examined by immunohistochemistry in benign and malignant thyroid neoplasms.The results showed that the positive rates of HGF and c-Met protein expressions in thyroid carcinomas were significantly higher than those of thyroid adenomas,and especially the expressions of HGF and c-Met proteins in follicular thyroid carcinomas were significantly higher than those in follicular thyroid adenomas.There existed significantly positive correlation between the expression degrees of HGF and c-Met in follicular thyroid carcinoma.Thus,the expressions of HGF and c-Met may be valuable in predicting prognosis of thyroid carcinomas and differentiating benign from malignant thyroid neoplasms.
