CHIMERIC CORAL LARVAE. " The globally distributed coral species Pocillopora damicornis is known to release either sexual or asexual derived planula-larvae in various reef locations...we documented the release of asexually derived chimeric larvae, originating from mosaicked maternal colonies that were also chimeras.” https://lnkd.in/d68A9uu View in LinkedIn

"INHERITED CHIMERISM is an alternative to the problematic practice of conjuring up additional, gene-donating symbionts at organelle origins to explain gene trees. It places no constraints on the collections of genes that the plastid and the mitochondrial symbionts possessed, other than that it needs to be a genome-sized collection, not tens of thousands of genes, and it allows freely for lateral gene transfer among prokaryotes before the endosymbionts become organelles and afterward. Lateral gene transfers among prokaryotes has received much attention in the past decades. Inherited chimerism incorporates lateral gene transfers among prokaryotes into endosymbiotic theory." https://lnkd.in/d4YBVjh View in LinkedIn

HYBRID PHOBIA. "The view that hybridisation threatens the genetic purity of parental species and is a violation of species integrity is pervasive throughout conservation literature. Furthermore, hybridisation is often considered to be an evolutionary dead end because genetic incompatibilities and combinations make hybrids unfit, sterile or absent." https://lnkd.in/dfcW_XQ View in LinkedIn

THE HAYFLICK LIMIT. "We showed that the death of cultured normal human cells was not due to some trivial cause involving medium components or culture conditions but was an inherent property of the cells themselves. The observation has since been confirmed in hundreds of laboratories." (Haflick). http://protein.bio.msu.ru/biokhimiya/contents/v62/full/62111380.html View in LinkedIn

CHANGING PARADIGM. "Nevertheless, what seemed in the 1950's to be incontrovertible evidence that the fate of all cultured cells was immortality, soon fell to new insights and a preponderance of opposing information." http://protein.bio.msu.ru/biokhimiya/contents/v62/full/62111380.html View in LinkedIn

TRANSFORMING CELLS. "Immortal cell populations still occasionally arise spontaneously from normal cell cultures by an unknown process. Today, however, they can be created purposely, albeit at low efficiency, by exposing normal, mortal cells to radiation, chemical carcinogens or certain oncogenic viruses." http://protein.bio.msu.ru/biokhimiya/contents/v62/full/62111380.html View in LinkedIn

TENABLE. "I think it is fair to say that our suggestion that the Phase III Phenomenon is aging at the cell level is still a tenable hypothesis even after thirty years of study. That is not to say that it has been proven unequivocally to be correct. This has not happened because there are no universally accepted criteria for defining biological aging." http://protein.bio.msu.ru/biokhimiya/contents/v62/full/62111380.html View in LinkedIn

HELD TRUE. "Aging and death is the inevitable consequence after about fifty population doublings." Worth repeating; called the Hayflick number. http://protein.bio.msu.ru/biokhimiya/contents/v62/full/62111380.html View in LinkedIn

PHASE III PHENOMENON. "We showed that when normal human embryonic cells are grown under the most favorable conditions, aging and death is the inevitable consequence after about fifty population doublings. We called this the Phase III Phenomenon." http://protein.bio.msu.ru/biokhimiya/contents/v62/full/62111380.html View in LinkedIn

"IMMORTAL CELL populations derived from a variety of human and animal tissues were reported to occur spontaneously in dozens of laboratories in the twenty year period from the early 1940's to the early l960's. These cell populations, now numbering in the hundreds, are best known by the prototype cell lines HeLa (derived from a human cervical carcinoma in 1952) and L cells (derived from mouse mesenchyme in 1943). They continue to flourish in cell culture laboratories throughout the world to this day." The source of some legal controversy for HeLa cells. http://protein.bio.msu.ru/biokhimiya/contents/v62/full/62111380.html View in LinkedIn
