Table 2. Summary of the Different Strategies to Increase Reprogramming Efficiencies and iPSC Colony Formation.

This table summarizes the various ways researchers have increased reprogramming efficiencies and iPSC colony formation. Table includes the specific reference associated with the method and the species of cells used. Method described in table is what is included in addition to the usual forced transcription of the reprogramming genes. This table is not an exhaustive list and is meant to be representative.
