干细胞与药物安全

科学家们成功将人类胚胎干细胞进行培养，并用生物高聚的细胞进行连接，这有望给临床前使用药毒性研究带来一场伟大的革新。这项技术的风险降到最低，并为临床研究带来极大益处。由于干细胞培养领域的技术不断进步，人们甚至可以在药物临床前实验开展之前，就用人类细胞甚至器官进行实验来验证药物的治疗效果。

Stem cells for drug safety

Cells cultured from human embryonic stem cells and linked up using biopolymer scaffolds are promising to revolutionise preclinical safety and toxicity studies. This technology holds the potential to minimise risk for human and animal subjects and bring massive benefits to clinical research. Thanks to ongoing research in the field of culturing stem cells, the therapeutic effect of medicines could soon be established in human cells and eventually organs even before preclinical trials begin.
