Contractile fibroblasts form a transient niche for the branching mammary epithelium (fibroblasts)

Single-cell RNA-seq of fibroblasts, FACS-sorted from microdissected regions of pubertal mouse mammary gland. The microdissected regions contained either terminal end buds with their surrounding stroma ("TEB" sample), or mature ducts with their surrounding stroma ("duct" sample). The animals were 5 weeks old females and each sample was pooled from 11 animals.本数据集为针对青春期小鼠乳腺显微切割区域中通过荧光激活细胞分选（Fluorescence Activated Cell Sorting，FACS）获取的成纤维细胞的单细胞RNA测序（single-cell RNA-seq）数据。所涉及的显微切割区域分为两类：一类为带有周围基质的末端芽体（terminal end buds，TEB）样本，另一类为带有周围基质的成熟导管样本。实验动物为5周龄雌性小鼠，每份样本均由11只小鼠的组织混合制备而成。
