Hope for Stroke Victims-Transplanting STEMEZ hNP1 Cells

In a recent publication (Jen et al., 2009) Neuromics'/ArunA’s STEMEZTM human neural progenitor (hNP1) cells when injected (sterotaxic) into a rat stroke model produced significant beneficial results. The hNP1 cells reduced the infarct area by 50% and were positive for neuronal marker proteins, cleaved caspase-3 and 40% of the cells showed spontaneous action potentials and excitatory postsynaptic currents measured by patch clamp recordings at 8 weeks post hNP1 cell injections. The treated rats had improves cognitive and sensorimotor functions between four to nine months post injection. These Sprague–Dawley rats were not immunosuppressed.

Transplantation of human neural precursor cells in Matrigel scaffolding improves outcome from focal cerebral ischemia after delayed postischemic treatment in rats.
