PASK phosphorylates Wdr5 to trigger epigenetic changes at lineage specifying promoters resulting in transcriptional derepression and differentiation of stem or progenitor cells.
Fibro-inflammatory progenitors represent a subpopulation of perivascular cells in visceral adipose tissues of mice that promote inflammation and fibrosis.
A group of cells that can become adipocytes controls the formation of blood vessels in the bone marrow, and also regulates the differentiation of resident mesenchymal progenitor cells.
Combined fate mapping and genetic deletion studies reveal that PDGFRα+ cells and PDGFRα gene itself are required for adipose tissue development but not for adult tissue homeostasis.
Murine periosteum is highly enriched for osteoprogenitors, many of which express αSMA, but fracture callus chondrocytes are partially derived from other sources.
The regulation of sympathetic innervation density by beige adipocytes in subcutaneous fat is important during a critical developmental window, but dispensable during adulthood.
