Sperm News and Research

RSS

The term sperm refers to the male reproductive cells. In the types of sexual reproduction known as anisogamy and oogamy, there is a marked difference in the size of the gametes with the smaller one being termed the "male" or sperm cell. The human sperm cell is haploid, so that its 23 chromosomes can join the 23 chromosomes of the female egg to form a diploid cell.

Cell fusion studies at Johns Hopkins could lead to improved treatments for muscular dystrophy

Researchers at Johns Hopkins have established a high-efficiency cell-cell fusion system, providing a new model to study how fusion works. The scientists showed that fusion between two cells is not equal and mutual as some assumed, but, rather, is initiated and driven by one of the fusion partners. The discovery, they say, could lead to improved treatments for muscular dystrophy, since muscle regeneration relies on cell fusion to make muscle fibers that contain hundreds or even thousands of nuclei.

Scientists explore development of unique dentition of 'toothed whales'

Whales are mammals, but they don't look like the mammals living around us, as they have a triangular fluke for tail, no hind legs and no body hair. And inside their mouths, their teeth are unfamiliar too - being much simpler and 'peg like'. A multidisciplinary team of researchers have now married together the fossil record and the embryonic development process to investigate how the whale got its teeth.

Exposure of human f-tal testicles to bisphenol A reduces testosterone production

Bisphenol A (BPA) is a chemical compound that is included in the composition of plastics and resins. It is used, for example, in the manufacture of food containers such as bottles and babies' feeding bottles. It is also found in the protective films used inside food and drink cans and on till receipts where it used as a discloser. Significant levels of BPA have also been found in human blood, urine, amniotic fluid and placentas.

New details about molecular surveillance system that helps detect and correct errors in cell division

Studies led by cell biologist Thomas Maresca at the University of Massachusetts Amherst are revealing new details about a molecular surveillance system that helps detect and correct errors in cell division that can lead to cell death or human diseases. Findings are reported in the current issue of the Journal of Cell Biology.

Researchers analyze impact of 3 unexpected sex determination factors

So, is it a girl or a boy? This is the first question parents ask at the birth of an infant. Though the answer is obvious, the mechanism of sex determination is much less so. Researchers at the University of Geneva (UNIGE) attempt to shed light on this complex process by identifying the crucial role played by insulin and IGF1 and IGF2 growth factors, a family of hormones known for its role in metabolism and growth.
