骨骼是癌症转移和恶性肿瘤的常见部位，由此产生的病变通常无法治愈。转移性癌细胞与骨微环境之间的相互作用对于癌细胞的存活、生长和进展至关重要。间充质干细胞 (MSC) 是骨骼中一种重要的基质细胞类型，因其对癌症诱发的骨疾病的影响而受到赞赏，然而，新的证据表明 MSC 在癌骨串扰中具有广泛的作用，包括癌细胞休眠、代谢需求和免疫肿瘤学。新出现的证据还表明，在研究 MSC 生物学时，MSC 组织来源的重要性以及衰老的影响。将这些考虑因素与空间转录组学等开发技术相结合，将有助于定义骨中复杂的间质癌相互作用的分子机制，并有助于识别治疗上易于处理的靶标。© 2024 作者。

The skeleton is a common site of cancer metastasis and malignancy with the resultant lesions often being incurable. Interactions between metastatic cancer cells and the bone microenvironment are critical for cancer cell survival, outgrowth, and progression. Mesenchymal Stem Cells (MSCs) are an essential stromal cell type in bone that are appreciated for their impacts on cancer-induced bone disease, however, newer evidence suggests that MSCs possess extensive roles in cancer-bone crosstalk, including cancer cell dormancy, metabolic demands, and immune-oncology. Emerging evidence has also identified the importance of MSC tissue source and the influence of ageing when studying MSC biology. Combining these considerations together with developing technologies such as spatial transcriptomics will contribute to defining the molecular mechanisms underlying complex stroma-cancer interactions in bone and assist with identification of therapeutically tractable targets.© 2024 The Authors.
