Fig 1. KISS1 and KISS1R are variably expressed in MSCs, OPCs, and tumor cell lines.

Protein expression of the kisspeptin precursor KISS1 and the receptor KISS1R was investigated in primary MSCs (A) and OPCs (B). Specificity of the KISS1R antibody was confirmed by the addition of a blocking antigen (C). Actin was used as a loading control. Dividing lines indicate samples, which were loaded on different gels.
