Van mijn goede voornemen om niet te lang te blijven op de Gentse Feesten en op tijd in mijn bed te kruipen om er vandaag vroeg uit te geraken, is niet veel in huis gekomen. Maar ja, wat wil je? Als je hoort dat om 23u Stef Bos naar het St-Baafsplein komt, dan kan je toch maar moeilijk naar huis gaan h

In biological and medical research, a HeLa cell is a cell which is derived from cervical cancer cells taken from a woman named Henrietta Lacks, who died from the cancer in 1951, and circulated (without Lacks's knowledge or permission) by George Gey. These cancer cells are considered "immortal" (that is, they do not die of old age and can divide an unlimited number of times, unlike most other human cells), and have been grown in cell culture in an unbroken lineage ever since.

This cell line was propagated for use in cancer research. Initially, the cell line was said to be named after a "Helen Lane", in order to preserve Lacks's anonymity. The cells proliferate abnormally rapidly, even compared to other cancers.

HeLa cells have been transformed by human papillomavirus 18 (HPV18), and have different properties from normal cervical cells.

They are used as model cancer cells and for studying cellular signal transduction.

HeLa cells have proven difficult to control. They sometimes contaminate other cell cultures growing in the same laboratory, interfering with biological research. The degree of contamination is unknown, because few researchers test the identity or purity of already-established cell lines. It has been claimed that a substantial fraction of in vitro cell lines are actually HeLa, their original cells having been overwhelmed by a rapidly growing population derived from HeLa contaminant cells. It has been estimated that the total mass of HeLa cells far exceeds that of the rest of Henrietta Lacks' body.

Some researchers have argued that these cells are a separate species, because they reproduce and spread on their own; in 1991 it was named and described as Helacyton gartleri.

Voor de cultuurbarbaar die het nog niet wist: de Gentse Feesten zijn weer begonnen. Van 16 tot en met 25 juli staat Gent weer helemaal op z'n kop dankzij dit fantastische cultureel volksfeest. Vandaag heb ik al een eerste bezoekje gebracht en genoten van uitstekende pleinartiesten met vuur en kettingzagen aan het Belfort, de Duveltent, het St-Baafsplein, de Vrijdagsmarkt en een terrasje aan het Vleeshuis. De sfeer was fantastisch, de opkomst enorm, de Duvel, Gentse Tripel en oliebollen hebben gesmaakt. B-) De avond was alvast goed geslaagd voor mij. Het deed me echt verlangen naar meer. Mijn statement dat de Genste Feesten voor mij niet goed zullen lukken wegens de stage, heeft plaats moeten maken voor de hoop elke avond wel minstens voor eventjes te kunnen afzakken naar het oude stadscentrum voor een tijdje puur genot.

Tot morgen!

Deze week heb ik, mede door mijn vermoeidheid niet echt veel tijd gehad om te bloggen. Ik was dan ook vergeten om jullie op de hoogte te houden van mijn resultaten op studiegebied waarvan de laatste onzekerheid donderdag verdwenen was. Een trouwe lezer mij hierop attent maakte.
