A mesodermal fate map for adipose tissue. (A) Schematic showing the mesodermal fate map for adipose tissue based on tracing with Meox1-Cre:mTmG, Pax7-Cre:mTmG and HoxB6-Cre:mTmG systems. Red, somitic mesoderm and derivative adipocyte lineages; yellow, central dermomyotome and derivative adipocyte lineages; blue, posterior lateral plate mesoderm and derivative adipocyte lineages. (B) Schematic showing a model fate map for interscapular adipocyte lineages based on Pax7-Cre:mTmG tracing in this study and Pax3/Myf5-Cre:mTmG tracing by Sanchez-Gurmaches and Guertin (2014). It is proposed that a subset of Pax3+ progenitors in the epaxial dermomyotome and Pax7/Pax3+ progenitors in the central dermomyotome are fated to the interscapular adipocyte lineage. These Pax3+ or Pax7/Pax3+ cells acquire Myf5 expression in a Pax3-dependent manner (Sato et al., 2010) and go on to establish interscapular white and brown adipocytes. (C) Schematic of somite subcompartments. (D) Model lineage hierarchy for interscapular adipocytes based on Pax7-Cre:mTmG tracing in this study and Pax3/Myf5-Cre:mTmG tracing by Sanchez-Gurmaches and Guertin (2014).
