基质胶应用于肿瘤体外模型的研究现状

Current status of applying matrigel to in vitro models for cancer reseach

肿瘤微环境的组分构成复杂,在肿瘤演进中发挥重要调节作用。细胞外基质(extracellular matrix,EMC)是肿瘤微环境中调控癌症进展的重要介质,将ECM加入肿瘤模型构建中,可以更完整地在体外模拟肿瘤微环境。作为类器官生长的介质,基质胶起到ECM的功能。常见的此类ECM来自小鼠肉瘤重组基底膜自然衍生的基质胶;因为基质胶存在批次间差异,影响实验的可重复性。为了克服此类问题,研究者们设计了合成基质胶。本文将根据目前肿瘤类器官培养过程中基质胶的研究和应用进展进行概述,为类器官培养、培养细节的不断优化提供参考,让肿瘤类器官的培养实现更高效和低成本,有助于更好地推动肿瘤研究的基础和临床转化,为癌症治疗和预防提供更有效的策略。

The components of the tumor microenvironment have a complex composition and play an important regulatory role in tumor evolution.The extracellular matrix(ECM)serves as a vital mediator in regulating cancer advancement within the TME.Incorporating ECM into tumor modeling allows for a more comprehensive simulation of the TME in vitro.As a medium for organoid growth,the matrix gel fulfills the functions of ECM.ECM is normally derived from the recombinant basement membrane of mouse sarcoma(Matrigel);however,batchto-batch variations in Matrigel affect experiment reproducibility.To overcome such issues,researchers have designed synthetic matrix gels.This paper provides an overview of the current research in the application of matrix gels for tumor organoid modeling,offering insights for continuous optimization of organoid culture,thereby achieving more efficient and cost-effective organoid construction and advancing the translation of basic research to clinical applications.
