Abstract

Extracellular vesicles (EVs) are lipid bilayer enclosed nanovesicles involved in intercellular communication. EVs are emerging as potential cancer biomarkers, providing insights into the condition of parent cancer cells. Their composition and entry into the bloodstream are influenced by factors such as tumor grade, type, and the configuration of the vascular network at the release site. In this work, we propose a computer simulation model to emulate the penetration of EVs into the bloodstream. We take into account convective and diffusive parameters that are influenced by the tumor’s characteristics, and the configuration of the vasculature and lymphatic network. We investigate the penetration rate of EVs into the bloodstream in terms of various parameters such as vessel wall permeability and the configuration of the vasculature and lymphatic networks. Our parametric study using a 2D model demonstrates that increasing the permeability coefficient, as observed in tumor tissue, could lead to a two-fold increase in EV penetration rate into the bloodstream. We believe that this model offers pre-experimental insights concerning liquid biopsy assays and the metastatic progression of the disease.

血液穿透细胞外囊泡的硅片研究

细胞外囊泡（EVs）是脂质双分子层封闭的纳米囊泡，参与细胞间的通讯。电动汽车正在成为潜在的癌症生物标志物，提供了对母体癌细胞状况的洞察。它们的组成和进入血流受到诸如肿瘤分级、类型和释放部位血管网络结构等因素的影响。在这项工作中，我们提出了一个计算机模拟模型来模拟电动汽车进入血液的渗透。我们考虑到对流和扩散参数是由肿瘤的特点，以及配置的血管和淋巴网络的影响。我们根据各种参数，如血管壁通透性和血管和淋巴网络的配置，研究了ev进入血液的渗透率。我们使用二维模型进行的参数化研究表明，在肿瘤组织中观察到，增加渗透系数可能导致EV进入血液的渗透率增加两倍。我们相信该模型提供了关于液体活检测定和疾病转移进展的实验前见解。

期刊介绍： As a result of recent advances in MEMS/NEMS and systems biology, as well as the emergence of synthetic bacteria and lab/process-on-a-chip techniques, it is now possible to design chemical “circuits”, custom organisms, micro/nanoscale swarms of devices, and a host of other new systems. This success opens up a new frontier for interdisciplinary communications techniques using chemistry, biology, and other principles that have not been considered in the communications literature. The IEEE Transactions on Molecular, Biological, and Multi-Scale Communications (T-MBMSC) is devoted to the principles, design, and analysis of communication systems that use physics beyond classical electromagnetism. This includes molecular, quantum, and other physical, chemical and biological techniques; as well as new communication techniques at small scales or across multiple scales (e.g., nano to micro to macro; note that strictly nanoscale systems, 1-100 nm, are outside the scope of this journal). Original research articles on one or more of the following topics are within scope: mathematical modeling, information/communication and network theoretic analysis, standardization and industrial applications, and analytical or experimental studies on communication processes or networks in biology. Contributions on related topics may also be considered for publication. Contributions from researchers outside the IEEE’s typical audience are encouraged.
