I say, \My darling, you were wonderful tonight. Oh my darling, you were wonderful tonight.\. It's late in the evening; she's wondering what clothes to wear. She puts on her make-up and brushes her long blonde hair.
(A) CD31 expression in lymph nodes showing positive marginal (subcapsular) sinuses, high endothelial venules (HEV), and capillaries. In contrast, marginal sinuses are negative for CD34 (B) and vWF (C). (D) Most of the cells present in lymph nodes including EC from capillaries and HEV are stained for Fli-1.D31, a member of the immunoglobulin superfamily, is a 130-kDa transmembrane glycoprotein also designated as PECAM-1 (platelet endothelial cell adhesion molecule 1). It is present on the surface of platelets, monocytes, macrophages, and neutrophils and is a constituent of the endothelial intercellular junction.
However, if the cells are TdT positive, MPO negative, CD33 negative, and demonstrate lymphoid markers, the leukemia is considered ALL. See an example of a flow cytometry study below. Diagnostic workup of a patient with preâB-cell acute lymphoblastic leukemia. Flow cytometry shows that the cells were positive for CD10, CD19, CD22, CD34, and terminal deoxynucleotidyl transferase. Cytogenetic abnormalities occur in approximately 70% of cases of ALL in adults (see Table 2, below).
