Mouse mammary epithelial cell subpopulations from pregnant and virgin mice

ABSTRACT: To study the effect of pregnancy on mouse mammary epithelial subpopulations, epthelial cells derived from virgin or pregnant (12.5 day pregnant) mice were isolated using fluorescence-activated cell sorting. After elimination of haematopoietic and endothelial cells, two distinct epithelial subpopulations were sorted using antibodies against CD29 and CD24. Based on the immunohistochemical phenotype, and in vivo and in vitro functional assays, these subpopulations were identified as mammary stem cell enriched (CD29hiCD24+) and luminal (CD29loCD24+) respectively (ref: Shackleton et al, Nature 2006). Microarray profiling was used to compare gene expression profiles of the two subpopulations in 12.5 day pregnant and virgin mice. For each biological replicate, mammary gland from virgin or 12.5 day pregnant FVB/NJ mice were collected and digested to obtain a single cell suspension. CD45-CD31-TER119- cells were then sorted based on the expression of cell surface markers CD24 and CD29. There were 4 pools of pregant mice and 3 pools of virgin mice.

Transcriptome profiles of mouse mammary stem cells and progenitor cells

Project description:MaSC, Luminal progenitor enriched subpopulations were isolated from virgin and pregnant mice based on using both surface marker or internal reporter transgene (GFP) expression. (Tiede BJ et al., 2009, PLoS ONE 4(11): e8035. doi:10.1371/journal.pone.0008035), and the transcirptome profiles were determined and compared. Two MaSC differential methods: CD24/CD29 & GFP reporter; two physiolgical condition: virgin vs pregnant; the combination of ((P4, GFPhi) vs (P5, P6, GFPlo)) x (vg vs pg)

Mammary epithelial cell subpopulations from control and ovariectomized mice

Project description:To study the effect of pregnancy on mouse mammary epithelial subpopulations, epthelial cells derived from control or ovariectomized adult mice were isolated using fluorescence-activated cell sorting. After elimination of haematopoietic and endothelial cells, two distinct epithelial subpopulations were sorted using antibodies against CD29 and CD24. Based on the immunohistochemical phenotype, and in vivo and in vitro functional assays, these subpopulations were identified as mammary stem cell enriched (CD29hiCD24+) and luminal (CD29loCD24+) respectively (ref: Shackleton et al, Nature 2006). Microarray profiling was used to compare gene expression profiles of the two subpopulations isolated from ovariectomized and control mice. For each of two biological replicates, 6 FVB/NJ mice were ovariectomized at 8 weeks of age. 4 weeks after ovariectomy (Ovx) mammary gland from control or Ovx animals were collected and digested to obtain a single cell suspension. CD45-CD31-TER119- cells were then sorted based on the expression of cell surface markers CD24 and CD29. Similarly for two pools of control mice. There were also 4 technical replicates, to make 12 BeadChips in total.

Transcriptome characterization of IFNa response in MaSC and luminal progenitor cells

Project description:Transcriptome response to IFNa treatment in MaSC, Luminal progenitor cells were studied. The MaSC, Luminal progenitor cells enriched subpopulations were sorted based on CD24/CD29 expression from mammary epithelial cells of virgin female mice . (Tiede BJ et al., 2009, PLoS ONE 4(11): e8035. doi:10.1371/journal.pone.0008035). The cells were cultured in mammosphere condition in vitro and treated with Ifna for 8 days. The total RNA samples are collected and compared using microarray analysis.

Genome-wide analysis of mRNA expression differences from various stem cell enriched sub-populations of mouse mammary epithelial cells

Project description:Microarrays were used to examine gene expression differences in four different sub-populations of mammary epithelial cells obtained through flow cytometry of stem cell markers for H2BGFP, CD24, and CD29. The present study aims to find the specific differences between these populations that influence their ability to repopulate mammary structures in vivo during transplantation assays. H2GFP+/CD24+/CD29lo cells were found to be multipotent and able to give rise to mammary structures capable of lactation, and this ability increased dramatically if the recipient mice were pregnant.

Transcription profiling of mouse mammary tumor-initiating cells

Project description:Using a syngeneic p53 null mouse mammary gland tumor model that closely mimics human breast cancer, we have identified by limiting dilution transplantation as well as in vitro mammosphere and clonogenic assays a Lin-CD29HighCD24High subpopulation of tumor-initiating cells. Differentially expressed genes in the Lin-CD29HighCD24High mouse mammary gland tumor-initiating cell population include those involved in DNA damage response and repair, as well as genes involved in epigenetic regulation previously shown to be critical for stem cell self-renewal. Experiment Overall Design: The cells were labeled (for FACS sorting) with CD29 and CD24 antibodies, and 4 subpopulations were collected (CD29HighCD24High, CD29HighCD24Low,CD29LowCD24High, and CD29LowCD24Low) to do either in vivo transplantation or to isolate RNA from each of them for array to correlate the in vivo data. Experiment Overall Design: 12 samples (RNA of 4 subpopulations based on expression of CD29 and CD24 for each tumor of 3) were included in the identification of differentially expressed genes of tumor-initiating cells. 5 samples (RNA of subpopulations based on expression of CD29 and CD24 of normal mammary epithelial cells ) were included in the normal group analysis. Reference RNA was used to normalize all samples.
