STEMCELL Technologies STEMcircles is a virus-free technique used for the generation of induced pluripotent stem cells.
STEMcircles involves introducing reprogramming factors to cells using tiny
circles of DNA. Unlike other techniques, this method, which is based on
standard molecular biology practices, does not use viruses to introduce
genes into the cells. Instead these DNA minicircles do not integrate into
the genome and are naturally lost as the cells divide, overcoming some the
safety concerns associated with current reprogramming methods.
The technique works because the vector contains the minimal DNA sequences
necessary for reprogramming. Unlike the larger, more commonly used DNA
plasmids, the minicircles contain no bacterial plasmid backbone DNA and as
such are able to evade silencing mechanisms that cells naturally use against
foreign DNA. The result is more robust gene expression, and superior
reprogramming over that of regular DNA plasmids.
