Lectin histochemistry of mucus-secreting cells in the calf bulbourethral gland
1991
More, J.
The bulbourethral glands of 2-month-old calves were studied by means of lectin histochemical methods. The lectin-binding sites for each considered lectin can be divided into three groups according to their zonal topography. In the first group including PNA, MPA, RCA1, SBA and BPA binding sites were seen in most of the secreting tubules and end pieces. In the second group (WGA, GS1, DBA, UEA, and Con A) the reactive cells were limited to a reduced number of tubuloalveolar units generally located at the periphery of the gland. The third group was composed of two lectins, GSII and LTA for which the bulbourethral parenchyma was unreactive. These findings can be related to the glandular activity of the calf bulbourethral gland except for restricted peripheral areas with an appearing functional differentiation. This duality in the histochemical nature of glycoconjugates was compared with previous results obtained in other groups of mammals.
