(Submitter supplied) The mammary epithelia are mainly composed of two distinct lineages, the basal and luminal cells. Due to the limitation of traditional transcriptome analysis of bulk mammary cells, the hierarchy and heterogeneity of mammary cells within these two lineages remain unclear. Hence, we have performed single cell RNA-seq on mammary epithelial cells of virgin and pregnant mice. Based on the respective gene expression profiles, we found mammary cells are highly heterogeneous and can be classified into distinct subgroups with signature markers. more...

(Submitter supplied) Background: Heterogeneity within the mouse mammary epithelium has been recently explored by single-cell RNA profiling. To further understand how cellular diversity changes during mammary development, we profiled single cells from different developmental stages including late embryogenesis, early postnatal, prepuberty, resting adult, mid-pregnancy, late-pregnancy, lactation and post-involution. We also compared the transcriptomes and chromatin accessibility of micro-dissected ducts versus terminal endbuds (TEBs) to help decipher the molecular properties of these specialized units that drive morphogenesis. more...

(Submitter supplied) Aging of the mammary gland is closely associated with increased susceptibility to breast cancer, yet there have been limited systematic studies of aging-induced alterations within this organ. Here we leveraged the power of high-throughput single-cell RNA-sequencing (scRNA-seq) to generate a detailed transcriptomic atlas of young and aged murine mammary tissues, including both epithelial and stromal cell types. more...

(Submitter supplied) Mammary glands were collected from 8 pregnant (12.5 day) mice and 8 adult (10 week old) female mice. Basal epithelial cells were FACS sorted. Freshly sorted cells were submitted to a Fluidigm C1 System machine for single cell capture and cDNA synthesis. Cells were visualized under the microscope to ensure integrity of the captured single cells prior to cDNA preparation. Libraries were prepared using the Nextera XT kit and sequencing was carried out on an Illumina NextSeq 500 to achieve paired-end 75 bp reads.

(Submitter supplied) CCAAT/enhancer binding protein beta (C/EBPb) is a member of a family of highly conserved transcription factors that regulates numerous genes involved in proliferation and differentiation in a variety of tissues. C/EBPb is deregulated in human breast cancer and germline deletion of this gene results in multiple defects in mammary gland development. We hypothesized that C/EBPb regulates mammary stem cell self-renewal, maintenance and/or differentiation through the regulation of multiple target genes that coordinate mammary gland development. more...

(Submitter supplied) By single-cell RNA-sequencing across 4 stages of embryonic development, we reconstructed the differentiation trajectories of multipotent mammary stem cells towards basal and luminal fate. Our data revealed that MaSCs can already be resolved into distinct populations exhibiting lineage commitment at the time coinciding with the first sprouting events of mammary branching morphogenesis (E15.5). Through an interactive web tool for the visualization of gene expression across our developmental atlas, we provide novel molecular markers for committed and multipotent MaSCs, and define their spatial distribution within the developing tissue. more...

(Submitter supplied) The mammary gland is a unique organ as it undergoes most of its development during puberty and adulthood. Characterising the hierarchy of the various mammary epithelial cells and how they are regulated in response to gestation, lactation and involution is important for understanding how breast cancer develops. Recent studies have used numerous markers to enrich, isolate and characterise the different epithelial cell compartments within the adult mammary gland. more...

(Submitter supplied) The organisation of the mammary epithelial cell hierarchy and how these cells relate to the presentation of human breast tumours is poorly understood. Our results demonstrate that the luminal cell compartment of the mouse mammary gland can be resolved into terminally differentiated oestrogen receptor (ER)+ luminal cells, ER+ luminal progenitors and ER- luminal progenitors. The ER+ luminal progenitors are unique in regards to cell survival, as they are relatively insensitive to loss of oestrogen and progesterone when compared to the other types of mammary epithelial cells. more...
