Tempo-iNStem ™

Human iPSC-derived Neural Progenitor Cells


Human iPSC-derived Neural Progenitor Cells

Neural stem cells are self-renewing, multipotent cells that can generate neurons and glial-specific cellular lineages. Primarily, neural stem cells differentiate into neurons, astrocytes, and oligodendrocytes. Neural progenitor cells are adult stem cells committed to their neural and glial lineages.

Tempo-iNStem™ cells are induced neural progenitor cells reprogrammed from human fibroblasts or blood cells using proprietary foot-print-free stem cell technologies. iNStem™ cells are cryopreserved at low passage numbers. Each vial will maintain 5 subsequent passages and expansions without spontaneous differentiations. Cells have been tested to be able to differentiate into multiple neural and glial subtypes. Each vial contains >1 x 106 cells. iNStem™  cells are characterized via standard morphological examinations and via immunocytochemistry methods against known marker proteins (such as Vimentin).

 Tempo’s iNStem™ are human iPSC-derived neural progenitor cells. They are derived from integration-free induced pluripotent stem cell (iPSC) lines under a fully defined proprietary neural induction condition. Tempo’s iNStem™  cells are polarized structures when plated as a monolayer in culture and express markers such as Vimentin. We have validated iNStem™ cells to be multipotent neural and glial progenitor cells, as they can be further differentiated into neural and glial cell types under specific in vitro serum-free/integration-free reprogramming conditions.
