The lack of consent and information are one side, but in addition to being an invaluable research tool, cell lines are also big business: The global market
for cell lines development (which includes cell lines and the media they grow in, and other reagents) is worth around 3 billion dollars, and it's growing fast.

The laboratory process, described in the journal Scientific Reports, entails genetically modifying a
line of human embryonic stem
cells to become fluorescent upon their differentiation to retinal ganglion
cells, and then using that
cell line for development of new differentiation methods and characterization of the resulting
cells.

The research, the team said, should not discourage the pursuit of experimental treatments but instead be heeded as a call to screen rigorously all
cell lines for mutations at various stages of
development as well as immediately before transplantation.
Salk scientists and colleagues have proposed new molecular criteria
for judging just how close any
line of laboratory - generated stem
cells comes to mimicking embryonic
cells seen in the very earliest stages of human
development, known as naïve stem
cells.
They tried hundreds of different recipes; eventually they discovered that if they mixed liver precursor
cells (derived from iPS
cells) with two other types of standard human
cell lines known to be important
for embryonic liver
development, then the
cells would spontaneously form a 4 to 5 - millimeter 3D structure called a liver bud.

My post-doctoral work on the identification of genes required
for normal germ
line development and fertility led to the discovery that the germ
line is exquisitely sensitive to mutations in components of the mitotic spindle that have the potential to lead to aneuploidy — this sensitivity may also extend to embryonic and adult stem
cells.
Beyond the expansion of the collection of barcoded
cell lines for testing larger panels of compounds, next steps will include determining whether PRISM can be used to study the complex interactions between different
cell types found within tumors, or to study tumor evolution during cancer
development or after cancer treatment.
Nevertheless, the religious and political right has decried the
development of embryonic stem
cell lines, and George W. Bush severed federal funding
for their
development.
Finally, analysis of tumors from clinical trials and
cell line models will allow discovery of mechanisms of sensitivity and resistance to AR and PI3K inhibitors, as well as biomarkers that can be used in the
development of new treatment regimens and selection of patients
for future trials.
The most famous, oldest, and most commonly used immortal
cell line, dubbed HeLa, originated in a tumor sample taken from an African - American woman, Henrietta Lacks, who is the subject of the recent book The Immortal Life of Henrietta Lacks.9 The tumor
cells, harvested at Johns Hopkins Hospital, gave rise to the eponymous HeLa
cell line which researchers have used continuously since her death in 1951
for numerous experiments, including Jonas Salk's
development of the polio vaccine.
Founded in 1925, the ATCC focuses on the acquisition, authentication, production, preservation,
development and distribution of standard reference microorganisms and
