electrospinning fibrous polymer scaffolds for tissue engineering and cell culture

<p class="jove_content">作为组织工程领域的的发展，是一个巨大的需求，生产更合适的材料和加工技术，以解决更复杂的器官和组织的要求（如机械和血管）。静电是一种流行的技术来创造，模仿原生细胞外基质的结构和大小规模的纤维支架。这些纤维支架也有用的，因为细胞培养基质的纤维可以被用来直接细胞的行为，包括干细胞的分化（见广泛的审查由莫克<em&gt;等。</em&gt;和西尔<em&gt;等。</em&gt;了解更多信息）。在这篇文章中，我们描述了静电纺丝聚合物的一般过程，作为一个例子，electrospin一个反应的光线照射交联透明质酸（见Ifkovits<em&gt;等。</em&gt;审查photocrosslinkable材料）。我们还介绍了进一步的处理能力，如photopatterning多聚合物支架形成。 Photopatterning可用于创建渠道和多尺度孔隙支架，以增加细胞浸润和组织分布。多聚合物支架是有用的，以便更好地调整棚架的属性（力学和退化），其中包括专为细胞浸润的孔隙度。此外，这些技术可以扩展到包括广泛的聚合物和反应macromers的创建提供必要的线索，开发成功的组织工程结构的复杂支架。</p>
