808-人类皮肤解剖结构的单细胞空间转录组图谱
from 聊聊Sci
这项研究通过 MERFISH 技术构建了涵盖 120万个细胞 的人体皮肤单细胞空间图谱。研究人员分析了来自 22名受试者、15个解剖部位 的样本,精确识别并定位了 45种细胞亚型。该研究揭示了皮肤在不同部位的细胞组成差异,并定义了 十个多细胞邻域,这些邻域共同维持着皮肤的结构和功能。通过对 配体-受体 对的分析,科学家发现 肿瘤坏死因子(TNF) 在维持免疫与间质细胞交流中起关键作用。最后,该图谱还揭示了皮肤疾病中邻域结构的失衡,为理解 疾病发病机制 和实现皮肤 解剖部位特异性治疗 提供了重要的分子生物学基础。References: Restrepo P, Wilder A, Houser A, et al.
