SACK-Xn 3C5 Adult Mouse Hair Follicle Stem Cells

Growing and expanding primary, differentiated adult cells in culture is difficult and laborious because many differentiated cells can only be maintained in vitro for a limited period of time. However, for controlled experiments, it may be necessary to maintain a consistent population of cells.

Maintaining a population of adult stem cells (ASCs), allows one to exponentially propagate a population of cells in vitro, and induce differentiation when desired. This is possible with SACK cell strains and specified cell culture conditions.

SACK ASC cell properties – Long-term propagation in xanthine (Xn)-supplemented medium

  • Suppressed asymmetric cell kinetics
  • Express the epithelial stem cell biomarker LGR-5
  • Xn-suppressed non-random sister chromatid segregation

Differentiated progeny cell properties – Xn-free medium, confluent monolayer, serum reduction

  • Sebocyte differentiation as well as other undefined cell types
  • Induced expression of K5, K10, and filaggrin

*Additional similar, but less well characterized, independent clonal cell strains are available. For more information, contact us.

Replacement of the SACK medium with differentiation conditions allows the expanded tissue stem cells to regain their in vivo homeostatic state of asymmetric self-renewal, which yields cells committed to tissue-specific differentiation.
