1 CD31(+) cells exclusively showed higher colony-forming activity. 2  PECAM-1 may play a role in regulation of apoptosis as well as adhesion of BCR/ABL-expressing cells to modulate their imatinib sensitivity and would be a possible candidate for therapeutic target in Ph+ leukemias. There was close correlation between the CD31 expression, MVD and prostate cancer bone metastasizing. 2  unstimulated monocytes limit the initial phase of platelet activation by collagen via a mechanism that is, at least in part, PECAM-1-dependent.
