The ENStem-A Human Neural progenitor Expansion Kit contains ENStem-A Human Neural Progenitors and optimized Expansion medium. ENStem-A Human Neural Progenitor Cells are derived from NIH approved H9 human embryonic stem cells (hESCs). Using a proprietary method developed by Aruna Biomedical, these hESC derived neural progenitors proliferate as an adherent cell monolayer and can readily differentiate into different neuronal subtypes. Detailed spectral analyses indicate ENStem-A cells retained a normal diploid karyotype in culture after ten passages. ENStem-ATM human neural progenitor cells may be used for a variety of research applications such as studies of neurotoxicity, neurogenesis, electrophysiology, neurotransmitter and receptor functions. ENStem-A Neural Expansion Medium is a defined serum-free formulation that has been optimized for the culture and expansion of ENStem-A Human Neural Progenitor Cells. When used in conjunction with FGF-2 (provided), the expansion medium will allow for the maintenance and proliferation of ENStem-A Human Neural Progenitor Cells.
