These human hippocampal stem cells have been launched for use in neuroscience and cytotoxicity testing. These cells have been extensively characterized for neural stem cell and mature neural markers. This human organ-derived product differentiates into functionally mature neurons, astrocytes, and oligodendrocytes, with neurons displaying abundant and mature excitatory and inhibitory synapses. The neural progenitors coupled with their growth medium enables expansion to a scale for high-throughput screening in 384-well cell culture plates with expansion from a characterized starting bank.
