In mice and other mammals, spermatogenesis is maintained by spermatogonial stem cells
(SSCs), a cell population belonging to undifferentiated type A spermatogonia. In the …

Glycobiology is the study of complex carbohydrates in biological systems and represents a
developing field of science that has made huge advances in the last half century. In fact, it …

The initial recognition between mammalian gametes at fertilization occurs at the zona
pellucida of the egg and the plasma membranes of the spermatozoa (Benoff, 1997; …

Lectin histochemistry is a useful method that allows the in situ identification of the terminal
sugar moieties of the carbohydrates that form the glycoconjugates. Moreover, when it is …

We have purified an isoform of protein disulfide isomerase (EC 5.3. 4.1) from rat liver, and
raised a specific antibody against the purified protein in rabbit. Immunohistochemical studies …

Human sex hormone-binding globulin (SHBG) binds estradiol and testosterone with high
affinity. Plasma SHBG is produced by hepatocytes, but the human SHBG gene is also …

Oligosaccharide chains of glycoproteins have been classified into two families according to
the nature of the link between the oligosaccharide and the polypeptide: N-and O-linked …

In the present study, some methodological factors affecting the acrosomal staining of frozen–
thawed Japanese Black bull spermatozoa were investigated by examining; the effect of …

Biochemical surface modifications occur during the capacitation and acrosome reaction of
human sperm and among those, variations in the expression of carbohydrates moieties. A …

The testes of prepubertal and adult horses were investigated using 10 horseradish
