<p>这些结果表明，锰输入通过电压门控性钙通道，锰可作为MRI造影剂的使用，还可以显示细胞活力。因此，我们建议，锰制导MRI可有用的监视后，人类胚胎干细胞移植到心肌细胞活力。 </p>

in vitro labeling of human embryonic stem cells for magnetic resonance imaging

<p class="jove_content">人类胚胎干细胞（胚胎干细胞）已经证明能够恢复受伤的心肌。磁共振成像（MRI）已成为主要的成像方法之一来评估受伤的心肌恢复。此外，前体内标签剂，如氧化铁纳米粒子，已被用于跟踪和本地化移植的干细胞。但是，这种方法不监视一个基本的细胞生物学特性，细胞移植的可行性。它已经知道，氯化锰（MnCl <sub>2）</sub>进入细胞，通过电压门控钙（ <sup>钙</sup>离子）当细胞生物活性的渠道，并积累细胞<sup>内</sup>产生T 1缩短的效果。因此，我们建议，锰制导MRI可有用的监视后的人类胚胎干细胞移植到心肌细胞的活力。 </p><p class="jove_content">在这段视频中，我们将展示如何与MnCl <sub>2</sub>和如何使用MRI体外，这些细胞可以清楚地看到标签的人类胚胎干细胞。与此同时，生物活性的Ca <sup>2 +</sup>渠道将调制利用双方的Ca <sup>2 +</sup>通道激动剂和拮抗剂，以评估随之而来的信号变化。 </p>
