Company Uses Fetal Cells From Abortions for Artificial Flavors
Washington, DC -- A pro-life group that monitors the use of cells from babies victimized by abortions is today bashing the biotech company Senomyx, which it says produces artificial flavor enhancers using aborted fetal cell lines to test their products.

The headline is somewhat misleading, and revolting.

The headline is not just misleading, it is a lie. Which makes getting behind a boycott like this somewhat difficult.
That being said, there is no way I would support use of any aborted tissue to be used for anything. You’re going down a slippery slope fast, to the point of when do women get pregnant just to “sell” their fetus to companies like this?
It is truly sick.
I'm not a scientist, but how are kidney cells also taste receptors?
Darn. I’m already “boycotting” those products — we never use them anyway.
Well Peta will not complain
Seems to me the headline could have just mentioned that the company is using cells from aborted human fetuses, period, and been more accurate and just as disgusting.
What a gracious thing to do. :)
Whoever writes these headlines speaks fluent moron.
The headline makes it sound like cannibalizm when in reality it is using fetal cells as lab rats.
Thoughtful, too. :)
HEK 293 isn't really a kidney cell; it's a neuron with neuronal ancestory. It's probably used to for it's sodium channels to discover salt substiutes.
Is it from the kidneys? How does that work?
MIsleading how? The cells are from murdered babies and being used to enhance flavors.
Origins of HEK 293 Cells
HEK 293 cells were generated in early 70s by transformation of cultures of normal human embryonic kidney cells with sheared adenovirus 5 DNA in Alex Van der Eb's laboratory in Leiden, Holland . The human embryonic kidney cells were obtained from a healthy aborted fetus and originally cultured by Van der Eb himself, and the transformation by adenovirus was performed by Frank Graham who published his findings in the late 1970s after he left Leiden for McMaster University in Canada. They are called HEK for human embryonic kidney, while the number 293 comes from Graham's habit of numbering his experiments; the original HEK 293 cell clone was simply the product of his 293rd experiment.
Subsequent analysis has shown that the transformation was brought about by an insert consisting of ~4.5 kilobases from the left arm of the viral genome, which became incorporated into human chromosome 19. For many years it was assumed that HEK 293 cells were generated by transformation of either a fibroblastic, endothelial or epithelial cell all of which are abundant in kidney. However the fact that the cells originated from cultured kidney cells does not say much about the exact cellular origin of the HEK 293, as embryonic kidney cultures may contain small numbers of almost all cell types of the body. In fact Graham and coworkers more recently provided evidence that HEK 293 cells and several other human cell lines generated by adenovirus transformation of human embryonic kidney cells have many properties of immature neurons, suggesting that the adenovirus was taken up and transformed a neuronal lineage cell in the original kidney culture. As a consequence, HEK 293 cells may need to be re-characterized and should not be used as an in vitro model for kidney cell function or studies involving kidney cells. Uses of HEK 293 Cells
As an experimentally transformed cell line, HEK 293 cells are not a particularly good model for normal cells, cancer cells, or any other kind of cell that is a fundamental object of research. However, they are extremely easy to work with, being straightforward to culture and to transfect, and so can be used in experiments in which the behavior of the cell itself is not of interest. Typically, these experiments involve transfecting in a gene (or combination of genes) of interest, and then analyzing the expressed protein; essentially, the cell is used simply as a test tube with a membrane. The widespread use of this cell line is due to its extreme transfectability by the various techniques, including calcium phosphate method, achieving efficiencies approaching 100%.
An important variant of this cell line is the 293T cell line that contains, in addition, the SV40 Large T-antigen, that allows for episomal replication of transfected plasmids containing the SV40 origin of replication. This allows for amplification of transfected plasmids and extended temporal expression of the desired gene products. Note that any similarly modified cell line can be used for this sort of work; HeLa, COS and Chinese Hamster Ovary cell are common alternatives.
I don't understand all of the above, but perhaps others will.
