«Through examination of Arabidopsis ovules by highly sensitive live - imaging, we were able to see that successful fertilization of the two female gametes triggers an unprecedented
cell fusion between the persistent synergid cell and the endosperm (SE fusion), which eventually leads to inactivation of the persistent synergid cell.»

However, by combining the capabilities of the Surface Forces Apparatus (SFA)-- a device that can measure the tiny forces generated by the interaction of two surfaces at the sub-nano scale — and simultaneous imaging using a fluorescence microscope, the researchers were able to see in real time how the
cell membranes rearrange in order to connect and open a
fusion conduit
between them.
Among these functions is the transport of lipids and other biomacromolecules
between cells via membrane adhesion and
fusion — processes that occur in many biological functions, including waste transport, egg fertilization and digestion.
Coleman added that further research is needed to determine whether
cell fusion events
between normal human
cell types result in genomic catastrophe and neoplastic transformation.
The study, published online on April 23, 2015 in the journal

A continuous cytoplasm
between the persistent synergid
cell and the endosperm was also observed, providing evidence for
fusion of the two
cells.
«New link found
between sex and viruses: A protein required for sperm - egg
fusion is identical to a protein viruses use to invade host
cells.»
To see what might go wrong with the telomeres of cloned animals
between cell fusion and maturity, a team led by Lenhard Rudolph of the Hannover School of Medicine and Heiner Niemann of the Institute for Animal Science at Mariensee, Germany, tracked the length of telomeres during development.
Ahn concluded that synergy
between the drug classes is possible but dependent on two unexpected factors: the location and strength of
fusion inhibitor binding to the envelope protein and the level of coreceptor expressed on the target
cell.
There are numerous, diverse mechanisms that allow a low frequency of gene movement
between species, such as accidental
fusion of
cells between different species, or the injection of DNA by bacteria into plant
cells.
