Tempo’s iOligo: human oligodendrocyte progenitor cells are derived from non-diseased human dermal cells, using integration-free induced pluripotent stem cell (iPSC) lines under a fully defined proprietary astroglial induction condition. Tempo’s iOligo (OPC) cells are branched structures when plated as a monolayer in culture and express oligodendrocyte markers such as O4, PDGFalphaR, NG2, and CNPase. iOligo can be used under T3 induction to express MBP, a marker protein of more mature oligodendrocytes.
