[Abstract]  We have developed a 2D heterotypic co-culture technique between fibroblasts and cancer cells that enables the study of the stromal reaction. For such, stromal cells are seeded and cultured immediately around a tumour cell line, and the cells establish cell-cell contacts, as well as a gradient of soluble factors throughout the stromal cells, similar to that found in tissues. Thus, this system also enables the researcher to distinguish between events that are caused by direct cell-cell contact and secreted factors. [摘要]  我们在成纤维细胞和癌细胞之间开发了二维异型共培养技术,可以研究基质反应。为此,将基质细胞接种并立即在肿瘤细胞系周围培养,并且细胞建立细胞 - 细胞接触以及遍及基质细胞的可溶性因子的梯度,类似于在组织中发现的。因此,该系统还使得研究者能够区分由直接的细胞 - 细胞接触和分泌因子引起的事件。

背景 组织内肿瘤的生长和存活取决于与周围基质细胞(如成纤维细胞,炎性细胞,内皮细胞和淋巴细胞)的相互作用。研究表明,随着肿瘤生长,癌细胞与周围成纤维细胞之间存在广泛的串扰。此外,肿瘤细胞可以将这些成纤维细胞激活成肿瘤相关成纤维细胞(TAF)。在某些情况下,这些成纤维细胞可能会限制肿瘤生长(Coulson-Thomas等人,2011和2013);然而,在许多情况下,这些TAF帮助肿瘤细胞生长和存活(Coulson-Thomas等,2010和2015)。因此,体外癌症研究也应考虑到TAF对癌细胞的保护作用。考虑到这一点,我们在成纤维细胞和癌细胞之间开发了2D异型共培养技术,可以在同一系统中研究TAF和癌细胞。
