Mammary alveologenesis is abrogated in the absence of the transcription factors STAT5A/5B that mediate cytokine signaling. To reveal the underlying causes for this developmental block we studied mammary stem and progenitor cells. While loss of STAT5A/5B did not affect the stem cell population and their ability to form mammary ducts, luminal progenitors were greatly reduced and unable to form alveoli during pregnancy. Temporally-controlled expression of transgenic STAT5A in mammary epithelium lacking STAT5A/5B restored the luminal progenitor population and rescued alveologenesis in a reversible fashion in vivo. Taken together, STAT5A is necessary and sufficient for the establishment of luminal progenitor cells.
Development of mammary luminal progenitor cells is controlled by the transcription factor STAT5A.

PPAR-γ is a major driver of the accumulation and phenotype of adipose tissue Treg cells.
Sex, Age, Specimen part, Treatment
View SamplesWe identified Pparg as a major orchestrator of the phenotype of adipose-tissue resident regulatory T cells (VAT Tregs). To establish the role of Pparg in shaping the VAT Tregs gene profile and cell dynamics, Tregs from lymph nodes and visceral adipose tissue of mice sufficient and deficient of Pparg expression in Tregs were double sorted for microarray analysis.
