Raw data from cell counting. Column 1: Fluorogold labeling of motoneurons projecting into the sciatic nerve, 4 d after axotomy. Columns 2 and 3: Cell counts of counterstained sections in column 1. Column 2: Ipsilateral to Fluorogold-labeled cells. Column 3: Contralateral to Fluorogold-labeled column. Number of animals in each group was 3; n.d., not determined.
