Tempo-iOligo™: Human iPS-derived Oligodendrocyte Progenitor Cells (OPCs)

Availability: In stock



Oligodendrocytes belong to the family of glial cells in the human central and peripheral nervous system. They are multifunctional cells and are implicated in many disabling neurological disorders, including adult-onset demyelinating disorders, as well as leukodystrophies and cerebral palsy.

Tempo’s iOligo™ are induced oligodendrocyte progenitors reprogrammed from human fibroblasts cells using proprietary foot-print-free stem cell technologies. iOligo™ cells are cryopreserved at low passage numbers. Each vial contains ~1.05 x 10cells. iOligo™ cells are characterized via standard morphological examinations and via immunocytochemistry methods against known marker proteins (such as O4, PDGFalphaR, NG2, and CNPase) and can be induced to express MBP upon T3 hormone induction.

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.
