Dermal dendrocyte hamartoma is characterized by a rounded, medallion-like lesion on the upper trunk in which there is a proliferation of fusiform CD34, factor XIIIa-positive cells in the mid and reticular dermis.
He further generated monoclonal antibodies specific for the hematopoietic stem cell marker, CD34.
Mastocytosis is a group of rare disorders of both children and adults caused by the presence of too many mast cells (mastocytes) and CD34+ mast cell precursors in a person's body.
The blasts react with antibodies to myeloperoxidase and antibodies to CD13, CD33, and CD34.

However, biomarker data collected during this study showed a decrease in VEGF-C, circulating endothelial cells, and CD146 and CD34/133 counts, and a maximum tolerated dose has still not been established.
Cells clustered on the wall of the dorsal aorta also expressed VE-cadherin as well as CD34, a common hematopoietic and endothelial marker; and CD45, a marker present on hematopoietic cells.
Fluorescence activation suggested that about 1/4 of these cells were CD133 positive CD24, CD34, and CD45 negative.
HEV cuboidal endothelial cells express the adhesion molecules GlyCAM-1 (in mucosal HEV this is MAdCAM-1), ICAM-1 and CD34.
