Protease activity involvement in the passage of mammalian sperm through the zona pellucida
(Sociedad de Biología de Chile, 2011)
QUANTITATIVE AND TOPOGRAPHIC ANALYSIS OF SULPHUR IN THE ZONA PELLUCIDA FROM MOUSE, HAMSTER AND RABBIT OOCYTES
(Sociedad Chilena de Anatomía, 1997)
Zona pellucida: An extracellular matrix with applications in the study of immunocontraception in domestic carnivores
(UNIV ZULIA, FACULTAD CIENCIAS VETERINARIAS, 2004-10)
Zona pellucida (ZP) is an extracellular matrix surrounding the mammalian oocyte. In most mammalian species this matrix consists of three families of glycoproteins likely to suffer several postraductional modifications to ...
Recombinant human zona pellucida protein C produced in Chinese hamster ovary cells binds to human spermatozoa and inhibits sperm-zona pellucida interaction
(Elsevier Science Inc, 2008-09)
Recombinant human zona pellucida protein C expressed in Chinese hamster ovary cells associates to the acrosomal region of human spermatozoa and inhibits sperm-zona pellucida interaction in the hemizona assay. Recombinant ...
Characterization of the functional domains of boar acrosin involved in nonenzymatic binding to homologous zona pellucida glycoproteins
(1998)
During the first steps of the gamete interaction, the proacrosin/acrosin system seems to play a crucial role in the secondary binding, holding acrosome-reacted spermatozoa during their passage through the zona pellucida. ...
Structural modifications induced by an in vitro maturation process in zona pellucida glycoproteins of bovine oocytes. A Raman microspectroscopy analysis
(Royal Society of Chemistry, 2016-08)
Oocyte quality is a determinant factor in the efficiency of an in vitro production process. Since the first oocyte–sperm interactions take place in the zona pellucida, the evaluation and characterization of this egg external ...
Human tubal secretion can modify the affinity of human spermatozoa for the zona pellucida
(Elsevier Science Inc, 2009-02)
Objective: To study the effect of the human tubal tissue conditioned medium (CM) on sperm parameters related to sperm-zona pellucida interaction. Design: Controlled experimental laboratory study. Setting: Research laboratory. ...
Function of the acrosomal matrix: zona pellucida 3 receptor (ZP3R/sp56) Is not essential for mouse fertilization
(Society For The Study Of Reproduction, 2012-01)
In mammalian fertilization, sperm-zona pellucida binding is considered to be a critical aspect of gamete interaction. In this study, we examine the mouse sperm acrosomal matrix protein zona pellucida 3 receptor (ZP3R; ...
Human spermatozoa selected by percoll gradient or swim-up are equally capable of binding to the human zona pellucida and undergoing the acrosome reaction
(Oxford University Press, 1991)
Several techniques have been used for selecting motile spermatozoa including Percoll and albumin gradients, swim-up, and glass wool filtration. A high yield of motile spermatozoa as well as an enhancement of motility are ...
