WNT5A and B-cell chronic lymphocytic leukemia: Previous studies showed autocrine of Wnt5a in neoplastic B cells [28], whereas WNT5A transcripts only present in neoplastic B cells in around 38% of patients with CLL [29], and high-levels of Wnt5a could be detected universally in their plasma [20, 21], suggesting cell-sources other than CLL neoplastic cells.
