1245-健康乳腺组织单细胞衰老图谱研究

from 聊聊Sci

这项研究通过单细胞测序技术,构建了健康小鼠乳腺组织老化的全面分子图谱。研究人员发现,随着年龄增长,乳腺中的上皮细胞、免疫细胞和基质细胞在比例和功能特征上均发生了显著偏移。具体而言,老年上皮细胞展现出明显的表观遗传重塑,其代谢、炎症及癌症相关基因的表达有所增强,且细胞谱系的保真度有所下降。在基质环境中,成纤维细胞转化为具有衰老特征及癌症相关表型,同时特定免疫细胞群体也发生了扩张。空间转录组分析进一步证实了这些衰老细胞在原位的空间交互。最后,研究指出小鼠乳腺的老化特征与人类乳腺肿瘤的基因表达谱存在关联,暗示了衰老微环境在癌症诱发中的潜在作用。References:Angarola B L, Sharma S, Katiyar N, et al.
