Induced Pluripotent Stem Cells (iPSC) From the Thirteen-lined Ground Squirrel


Hibernation in mammals is a seasonal state of metabolic suppression and dormancy characterized by a decrease in body temperature to survive extreme environmental stresses. Small hibernators such as 13-lined ground squirrels use this remarkable strategy to survive extreme environmental stresses like cold and restricted food supply.

Product: A new iPSC line from the neural precursor cells of wild type thirteen-lined ground squirrel (Spermophilus tridecemlineatus).

Use: This ground squirrel iPSC line can be differentiated into many different cell types for hibernation studies, disease modeling, and drug screening for neuronal injuries or other diseases

Competitive Advantage: This is the first iPSC line established from small hibernators like ground squirrel. These lines are useful in generating various cell types and tissue models for in-depth mechanistic studies of hibernation and coldness tolerance in vitro.
