A Quote by Adam Curtis
Henrietta Lacks' cells are immortal. They are known as the HeLa cell line, and they have become deeply involved in all sorts of medical and genetic research - sometimes in the most unexpected ways.

To date, embryonic stem cell research has not produced a single medical treatment, where ethical, adult stem cell research has produced some 67 medical miracles.
The Stem Cell Research Enhancement Act would expand research on embryonic stem cells by increasing the number of lines stem cells that would be eligible for federally funded research.
Only cells that had been transformed by a virus or a genetic mutation had the potential to become immortal.
Today, it is research with human embryonic stem cells and attempts to prepare cloned stem cells for research and medical therapies that are being disavowed as being ethically unacceptable.
We have a lot to gain through furthering stem cell research, but medical breakthroughs should be fundamentally about saving, not destroying, human life. Therefore, I support stem cell research that does not destroy the embryo.
The first misconception is that embryonic stem cell research is not legal. The fact is, embryonic stem cell research is completely legal. Research on embryonic stem cells has taken place for years.
The number of cells in our bodies is defined by an equilibrium of opposing forces: mitosis adds cells, while programmed cell death removes them. Just as too much cell division can lead to a pathological increase in cell number, so can too little cell death.
For me personally, the technology that has taken the most unexpected turn in my lifetime is what I refer to as 'the device formerly known as the cell phone.' I still remember many predictions that by 2000 there would only be about a million cell phone users. Boy, were they ever wrong!
Cancer cells have had so many other things go wrong with them, genetic, non-genetic changes, that those cells, one of the things they then get selected for is that they have lots of telomerase because now the telomeres in those cells get maintained.
I have always been fascinated by the story of Henrietta Lacks.
One can envisage taking cells from a patient with sickle-cell anaemia or an inherited blood disorder and using the Cas9 system to fix the underlying genetic cause of the disease by putting those cells back into the patient and allowing them to make copies of themselves to support the patient's blood.
In science there is something known as a stem cell. A stem cell is an undifferentiated cell which has not yet decided whether it's gonna be a cell of your brain or a cell of your heart or of your finger nail. But science is learning how to coax, how to manipulate, the raw material of life that we call stem cell to become any cell of the body. I think that God is the stem cell of the universe.
In medical school, students are immersed in the realm of medical ethics. It's where new doctors study, learn right and wrong, ask tough questions, and discuss things like end of life care, genetic testing, and patients' rights. In lots of ways, it's the most important part of being a compassionate and competent doctor.
For the last century of neuroscience, lots of people have tried to control neurons using all sorts of different technologies - pharmacology (drugs), electrical pulses, and so on. But none of these technologies are precise. With optogenetics, we can aim light at a single cell, or a set of cells, and turn just that set of cells on or off.
Iraq has the most extensive petrochemical industry in the Middle East and a wealth of vaccine factories, single-cell protein research labs, medical and veterinary manufacturing centers and water treatment plants.
Through their work with fetal tissue, researchers hope to find ways to harness embryonic stem cells which have the ability to become any type of human cell and could provide new treatments for many illnesses.
