It has been recognized in the scientific community that the use
of embryonic stem cells in research will become more and more important.
It would accommodate evolving and expanding areas of stem cell study, serving as a university and regional hub for human
embryonic stem cell research.
Establish a world - wide consortium of mouse production centers to generate germ line transmission of targeted knockout mutations
in embryonic stem cells for all known and predicted mouse genes.
Labs that derive new human
embryonic stem cell lines are few, partly because they can not get financial support from federal sources.
Several other states have stepped up to the plate in the wake of federal restrictions
on embryonic stem cell research.
A federal judge has issued a temporary injunction to halt the increase of federal funding
for embryonic stem cell research.
During that time, she applied her knowledge of the processes governing normal heart development to direct the differentiation of
embryonic stem cells into the cardiac lineage.
Given these facts, I do not understand why we should prefer an ethically and scientifically doubtful method
like embryonic stem cell research.
Those will be used to
derive embryonic stem cell lines, which can be turned back into embryos to make litters of live mice when they are needed for study.
The starting point in the debate
over embryonic stem cell research focuses on the status of the youngest of humans: Is it a person or a piece of property?
ACT scientists modified a diagnostic procedure used in fertility clinics to create the
first embryonic stem cell lines without destroying the embryos in the process.
He ruled that work on
existing embryonic stem cell lines derived outside federally funded labs did not violate a ban on the destruction of embryos.
Federal officials have approved the start of human
embryonic stem cell treatment experiments on patients suffering a leading cause of vision loss.
Since embryonic stem cells were first cultured in the lab more than 30 years ago, researchers have talked up their therapeutic potential.
Unlike embryonic stem cells, the use of adult stem cells in research and therapy is not controversial because the production of adult stem cells does not require the destruction of an embryo.
He plans to figure out how and if the sequence of developmental signals
directs embryonic stem cells to transform into more specialized cell types.
129 mice are widely used in the production of targeted mutations due to the availability of
multiple embryonic stem cell lines derived from them.
Therefore, the need for research with human
embryonic stem cells still exists despite the availability of new cell sources, the guidelines say.
In the meantime a large number of federally funded human
embryonic stem cell projects have been placed on hold, and even more are potentially at risk.
In consequence, with the current scientific knowledge, it can only be a backup choice — in absence of
embryonic stem cell model.
Of course,
such embryonic stem cells are not available in adult patients, so being able to create them from regular cells is an important step.
This
allows embryonic stem cells to be employed as useful tools for both research and regenerative medicine, because they can produce limitless numbers of themselves for continued research or clinical use.
For example, «we shouldn't just develop
[embryonic stem cells] at the expense of looking at other areas,» he warns.
Replacement tissue that avoids rejection by a patient's immune system is a step closer to the clinic, as researchers have created human
embryonic stem cells carrying the DNA of specific adults.
