SACK-Xs Lig-8 Clonal Adult Rat Hepatocytic 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 xanthosine (Xs)-supplemented medium

  • Suppressed asymmetric cell kinetics

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

Hepatocyte Properties

  • Albumin secretion
  • Alpha-fetoprotein secretion (indicates presence of hepatoblasts)
  • Alpha 1-antitrypsin expression
  • H4 hepatocyte antigen expression
  • Inducible cytochrome P450 activity (CYP1A1, CYP1A2)
  • Constitutive cytochrome P450 metabolism (CYP2E1)
  • Spheroid formation
  • Binucleation

Biliary Properties

  • CK7 expression (biliary epithelial cell marker)

*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.
