Researchers used embryonic stem (ES) cells to identify genes controlling the early stages of adipogenesis. Studying leukemia inhibitory factor (LIF) deficient cells revealed insights into stem cell commitment to the adipocyte lineage.

Area of Science:

  • Cell Biology
  • Developmental Biology
  • Stem Cell Research

Background:

  • Terminal differentiation of preadipocytes into adipocytes is well-studied.
  • Master genes regulating the transition from mesenchymal stem cells to adipoblasts remain unidentified.

Purpose of the Study:

  • To investigate early adipogenesis using embryonic stem (ES) cells.
  • To identify factors governing stem cell commitment to the adipogenic pathway.
  • To utilize mutant ES cells for studying gene function in adipose development.

Main Methods:

  • Employing embryonic stem (ES) cells, including those deficient in leukemia inhibitory factor (lif-/-) and its receptor (lifr-/-).
  • Assessing the adipocyte differentiation capacity of these mutant ES cells.

Main Results:

  • The study reports on the adipocyte differentiation capacity of lif-/- and lifr-/- ES cells.
  • This application demonstrates the utility of mutant ES cells in dissecting gene function during adipogenesis.

Conclusions:

  • Embryonic stem cells provide a valuable model for studying early adipogenesis.
  • Mutant ES cell lines, such as those lacking LIF signaling, are effective tools for identifying key genes in adipocyte development.
