Simultaneous demonstration of mast cells and blood vessels by the combined method CD34--alcian blue-safranin in lip tumors.
The aim of the study was to evaluate the mast cell-blood vessel relationship using double staining CD34/AAS. Sections from 14 cases with lip tumors have been stained with Hematoxylin-Eosin. On additional sections from each case, we highlighted blood vessels by immunohistochemistry for CD34 antigen using the method LSAB2-HRP/DAB, followed by alcian blue-safranin stain for mast cells. We quantifi...
متن کاملDifferentiation and Proliferation of Embryonic Mast Cells of the Rat
Histochemical reactions and radioautography were used to investigate the sequence of mast cell development in rat embryos. Mast cells arise ubiquitously in and are confined to the loose connective tissue in the embryo. The alcian blue-safranin reaction distinguishes between weakly sulfated and strongly sulfated mucopolysaccharides by a shift from alcian blue to safranin staining. Based on this ...
متن کاملTemperature-dependent staining reaction of chromatin by Alcian blue.
After treatment with Alcian blue at high temperatures, nuclei from chicken blood smears showed an intense staining reaction, which proved to be dependent on the DNA content of chromatin. The possibility that interactions between the phthalocyanine chromophore and unpaired bases accounts for this temperature-dependent staining of chromatin is briefly discussed.
متن کاملEffects of Oxidation upon Alcian Blue Staining of Acid Mucopolysaccharides.
Since Steedman ( 1950) has introduced it into histochemistry, alcian blue has been advocated to reveal a staining selectivity which depends upon the presence of acidic groups in mucopolysaccharides (Mowry, 1956; Pearse, 1960). As a plausible ground of this concept the fact has been presented that the alcian blue staining of polysaccharides can be increased in intensity, when acidic groups are i...
متن کاملBasophil counting with a new staining method using alcian blue.
Difficulties in obtaining reproducible and accurate enumeration of circulating basophils with existing techniques have hampered investigation of this infrequent cell population. A new basophil staining method is described that employs alcian blue dye for staining of heparin within basophils at low pH and in the presence of lanthanum ions. Basophil recognition is facilitated by reducing nonspeci...
