Cell surface ROR1 expression on primary ALL blasts.

<p>(<b>A</b>) Immunohistochemical analysis of FFPE slides of bone marrow from a pre-B-ALL patient with hyperdiploid genotype (ID 35; <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0052655#pone-0052655-t001" target="_blank">Table 1</a>) probed with normal goat pAbs (control; middle panel) and goat anti-human ROR1 pAbs (ROR1; right panel). The nuclei of ALL blasts were identified by hematoxylin and eosin staining (H&E; left panel). (<b>B</b>) Proportion of ROR1+ cases by genotype based on 56 pediatric ALL patients (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0052655#pone-0052655-t001" target="_blank">Table 1</a>).
