Sexual reproduction requires the fusion of sperm cell and oocyte during fertilization to
produce the diploid zygote. In mammals complex changes in the plasma membrane of the …

After leaving the testis, mammalian spermatozoa from many species are morphologically
differentiated but have acquired neither progressive motility nor the ability to fertilize a …

A group of similar proteins, namely BSP-A1, BSP-A2, BSP-A3, and BSP-30-kDa (collectively
called BSP proteins), are the major proteins found in bovine seminal fluid. These proteins …

Cell surface protein–carbohydrate interactions are essential for tissue-specific recognition
and endocytosis of viruses, some bacteria and their toxins, and many glycoproteins. Often …

Poor motility and abnormal acrosomal morphology only partially explain the reduced fertility
of cryopreserved bovine spermatozoa. To test the hypothesis that cryopreservation …

Glycodelin, also known as placental protein 14 (PP14) or progesterone-associated
endometrial protein (PAEP), is a human glycoprotein with potent immunosuppressive and …

Within the past few years, lectins have become a well-established means for understanding
varied aspects of cancer and metastasis. Evidence is now emerging that lectins are dynamic …

Recent progress, briefly reviewed here, has led to utility of bovine in vitro oocyte maturation
(IVM), in vitro fertilization (IVF), embryo culture and embryo transfer (ET) technologies in …

Bovine seminal vesicles synthesize a family of closely related proteins, namely BSP-A1,
BSP-A2, BSP-A3, and BSP-30-kDa (collectively called BSP proteins). Recently, we showed …

We serendipitously discovered that the marine bacterium Vibrio fischeri induces sexual
reproduction in one of the closest living relatives of animals, the choanoflagellate …
