(Submitter supplied) The mammary epithelial cell (MEC) system is a bi-layered ductal epithelial network consisting of luminal and basal cells, maintained by a lineage of stem and progenitor cell populations. Here, we used integrated single-cell transcriptomics and chromatin accessibility analysis to reconstruct the cell types of the mouse MEC system and their underlying gene regulatory features in an unbiased manner. We define differentiation states within the secretory type of luminal cells, which can be defined as a continuous spectrum of progenitor and mature secretory cells. 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) 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 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) 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...

(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) Chromatin remodeling is a key requirement for transcriptional control of cellular differentiation. However, the factors that alter chromatin architecture in mammary stem cells (MaSCs) are poorly understood. Here we show that Bptf, the largest subunit of the NURF chromatin remodeling complex, is essential for MaSC self-renewal and differentiation of epithelial cells in the mammary gland. Bptf depletion arrests cells at a previously undefined stage of epithelial differentiation that is associated with an incapacity to achieve the luminal cell fate. more...

The FACS sorted mammary stem cell (MaSC)/basal population from Pygo2 SSKO mammary gland displays biased differentiation towards luminal/alveolar lineage in vitro, and reduced regeneration rate of new mammary gland in vivo
