Cohort #2: hGRPs did not express the astrocyte glutamate transporter GLT1 in SOD1^G93A cervical spinal cord.

<p>Immunohistochemical analysis human GRP transplant-derived cells does not reveal expression of the astrocyte glutamate transporter, GLT1, in the SOD1^G93A spinal cord at disease endstage (<b>A</b>–<b>C</b>). Intraspinal levels of GLT1 were measured using Western blotting of whole cervical spinal cord segments at C5. hGRPs did not slow the loss of intraspinal GLT1 protein levels compared to hF controls (<b>D</b>). Asterisks denote regions with large numbers of transplant-derived cells, but no GLT1 expression. Scale bars: 200 µm.
