An integrative approach based on microfluidic design and stem cell biology enables capture of the spatial-temporal environmental evolution underpinning epigenetic remodeling and the morphogenetic process. We examine the body of literature that encompasses microfluidic applications where human induced pluripotent stem cells are derived starting from human somatic cells and where human pluripotent stem cells are differentiated into different cell types. We focus on recent studies where the intrinsic features of microfluidics have been exploited to control the reprogramming and differentiation trajectory at the microscale, including the capability of manipulating the fluid velocity field, mass transport regime, and controllable composition within micro- to nanoliter volumes in space and time. We also discuss studies of emerging microfluidic technologies and applications. Finally, we critically discuss perspectives and challenges in the field and how these could be instrumental for bringing about significant biological advances in the field of stem cell engineering.
基于微流控设计和干细胞生物学的综合方法能够捕捉到表观遗传重塑和形态发生过程的时空环境演变。我们研究了涵盖微流控应用的文献,其中包括从人类体细胞中获得人类诱导多能干细胞的应用,以及将人类多能干细胞分化为不同细胞类型的应用。我们专注于最近的研究,这些研究利用微流控的固有特性在微尺度上控制重编程和分化轨迹,包括操纵流体速度场、质量传输状态以及在微到纳升体积内的可控组成的能力,在空间和时间上。我们还讨论了新兴的微流控技术和应用的研究。最后,我们批判性地讨论了该领域的观点和挑战,以及这些观点和挑战如何为干细胞工程领域带来重大的生物学进展。
