随着我们应用从组织工程、合成生物学、微制造和纳米技术、系统生物学和发育生物学等子学科获得的知识,开发日益复杂的集成细胞系统将是下一个十年及以后的主要挑战。在这种前景下,我们在区分源细胞和更原始的、多能细胞的背景下描述当前的最新技术,并将这些细胞组织成单一细胞类型的群体,以产生更高级系统的组件或构件,最后,结合多种细胞类型,可能与具有特定物理或化学特性的支架相结合,以产生更大的功能。随着这些“活着的机器”能力的增强,表现出新的行为,并可能揭示自我组装、自我修复、甚至自我复制的能力,关于这项工作的伦理含义的问题就出现了。未来的前景以及解决这些复杂的伦理问题的方法将被讨论。
Development of increasingly complex integrated cellular systems will be a major challenge for the next decade and beyond, as we apply the knowledge gained from the sub-disciplines of tissue engineering, synthetic biology, micro-fabrication and nanotechnology, systems biology, and developmental biology. In this prospective, we describe the current state-of-the-art in the context of differentiating source cells from more primitive, pluripotent cells, and organizing these cells into populations of a single cell type to produce the components or building blocks of higher order systems and finally, combining multiple cell types, possibly in combination with scaffolds possessing specific physical or chemical properties, to produce greater functionality. As these “living machines” increase in capabilities, exhibit emergent behavior and potentially reveal the ability for self-assembly, self-repair, and even self-replication, questions arise regarding the ethical implications of this work. Future prospects as well as ways of addressing these complex ethical questions will be addressed.
