This action funds Joshua M. Grolman of the University of Illinois at Urbana-Champaign to conduct a research project in Biology and Engineering during the summer of 2013 at Yonsei University in Seoul, South Korea. The project title is "Nerves on a Chip: Artificial Neuronal Fibers as Model Biological Systems." The host scientist is Professor Injae Shin.Alginate hydrogels have been widely used as encapsulant materials due to their biocompatibility and ease of forming a gel. However, producing alginate hydrogels in the desired form and function can be impractical, particularly when considering the complicated patterns required for tissue engineering applications. To address these limitations, this work demonstrates a method of forming intricate fibers using a simple micro-scale device and subsequently seeding the constructs with P19 cancer cells. These cell-laden fibers can then be mounted and exposed to retinoic acid to induce change into neural tissue, which may serve as biological models to study White Matter Tracks and neural networks. The implications of a successful biological model of neuronal fibers would be far-reaching, both in treatement applications, as well as a tool for deeper understanding of the underlying biology. Typically, such systems in vivo are very complex and difficult to study due to a lack of control over many of the variables. Broader impacts of an EAPSI fellowship include providing the Fellow a first-hand research experience outside the U.S.; an introduction to the science, science policy, and scientific infrastructure of the respective location; and an orientation to the society, culture and language. These activities meet the NSF goal to educate for international collaborations early in the career of its scientists, engineers, and educators, thus ensuring a globally aware U.S. scientific workforce. Furthermore, the results of these studies will be published in a peer-reviewed journal and disseminated within the academic community help further medical research.

这项行动资助了约书亚·M。2013年夏天，伊利诺伊大学厄巴纳-香槟分校的Grolman在韩国首尔的延世大学进行了一个生物学和工程学的研究项目。 该项目的名称是“芯片上的神经：作为生物系统模型的人工神经纤维”。“主持科学家是Injae Shin教授。海藻酸盐水凝胶由于其生物相容性和易于形成凝胶而被广泛用作密封材料。 然而，以所需的形式和功能生产藻酸盐水凝胶可能是不切实际的，特别是当考虑到组织工程应用所需的复杂图案时。 为了解决这些局限性，这项工作展示了一种使用简单的微型装置形成复杂纤维的方法，随后用P19癌细胞接种构建体。 然后可以固定这些载有细胞的纤维并暴露于视黄酸以诱导神经组织的变化，其可以用作研究白色物质轨道和神经网络的生物模型。成功的神经元纤维生物模型的意义将是深远的，无论是在治疗应用，以及更深入地了解潜在的生物学的工具。 通常，由于缺乏对许多变量的控制，体内的这种系统非常复杂且难以研究。 EAPSI奖学金的更广泛的影响包括为研究员提供美国以外的第一手研究经验;介绍各自所在地的科学，科学政策和科学基础设施;以及社会，文化和语言的方向。 这些活动符合美国国家科学基金会的目标，即在科学家、工程师和教育工作者职业生涯的早期进行国际合作教育，从而确保美国科学劳动力具有全球意识。 此外，这些研究的结果将发表在同行评审的期刊上，并在学术界传播，以帮助进一步的医学研究。
