No tohle je to ono. To co nedava smysl.Původně odeslal karas45
Byla to prvni objevena linie a nahodou - ne jako vsechny ostatni, je zdaleka nejodolnejsi a pronika laboratorema? Proc to nedelaji ty ostatni linie?
nahodou to nekdo objevil a nahodou hned na zacatku a od ty doby neni zadna jina zivotaschopna linie u ktery by se nekdo pokousel o tohle:
Abych to zkratil. Me prijde, ze ty Hela bunky nejak musely byt aspon castecne pritomny mimo tu cernosku a ze ji nekdo pouzil jako nejakyho nositele/replikator/pokusny morce nebo tak neco anebo tu proste byly uz predtim a nikdo si toho nevsim a anhodou se nasly v ni, ale pak nedava smysl, proc by se nenasly jeste v nekom jinem. Bohuzel nejsem genetik, tak si tuhle hypotezu nemuzu zfalzifikovat... a to je duvod proc to sem cely pisu.Due to their ability to replicate indefinitely, and their non-human number of chromosomes, HeLa was described by Leigh Van Valen as an example of the contemporary creation of a new species, Helacyton gartleri. The species was named after Stanley M. Gartler, whom Van Valen credits with discovering "the remarkable success of this species."[45] His argument for speciation depends on these points:
The chromosomal incompatibility of HeLa cells with humans.
The ecological niche of HeLa cells.
Their ability to persist and expand well beyond the desires of human cultivators.
HeLa can be defined as a species as it has its own clonal karyotype.[46]
This definition has not been followed by others in the scientific community, nor, indeed, has it been widely noted.[citation needed]
As well as proposing a new species for HeLa cells, Van Valen proposed in the same paper the new family Helacytidae and the genus Helacyton.[45] Recognition of Van Valen and Maiorana's names, however, renders Homo and Hominidae paraphyletic because Helacyton gartleri is most closely related to Homo sapiens.[citation needed]
However this proposal has not been taken seriously by other prominent evolutionary biologists or scientists in other disciplines. Van Valen’s argument of HeLa being a new species does not fulfill the criteria for an independent unicellular asexually reproducing species because of the notorious instability of the cancer karyotype and their lack of a strict ancestral-descendant lineage.[47][48] What is clear however is that they are not good representatives of human cells[citation needed] and if used as such should preferably be used alongside other human derived cell lines,[citation needed] with more normal karyotypes.
Konspiracni teorie je mozna moc silny vyjadreni, mozna se nekdo snazil zakrejt trapne nejakej pruser. Podobne pokud teda ty Hela bunky se dostaly k Rusakum spionazi, tak proc se o tom nemluvi aspon ted? A proc by s tim Rusaci prisli jako s velkym obejvem? At je to jakkoliv, tak v cem spocivala ta trapnost situace? Ze to prokazalo spionaz misto par let ztraceneho vyzkumu a vsem insiderum to bylo jasny? Pak i ten odhalujici dokument laikum neodhaluje nic.
Proste me zajima jestli existuji ty jine linie, ktere jsou schopne samostatne zit jako HeLa bunky. Podle me ty jine linie dnes existuji, protoze moznosti kultivace jsou jine nez pred 60ti lety, kdy jim vsechno ostatni umrelo. Ale proc se sakra nenasly jine - podobne samostatne zijici "organismy" od te doby?
Ten dokument je proste zajimavej tim, ze mam po nem bordel v hlave a jasny neni nic. Treba nekdy nekdo zavitate na nejakou diskuzi s odbornikem, tak se ho na to zeptejte. Ja se po tom urcite pidit budu dal.<div style="font-size: xx-small;color: #0000ff;display: inline-block;text-align: center;width: 100%;">
