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.
Immunohistochemical panels for the diagnosis of Hodgkins disease typically employ CD15 along with CD30 and CD45; the latter does not stain Reed-Sternberg cells, but does stain almost all other lymphoid cells.
