Stem cell
researchers are heralding a "major scientific discovery", with the
potential to start a new age of personalised medicine.
Scientists
in Japan showed stem cells can now be made quickly just by dipping blood cells
into acid.
Stem cells
can transform into any tissue and are already being trialled for healing the
eye, heart and brain.
The latest
development, published in the journal Nature, could make the technology
cheaper, faster and safer.
The human
body is built of cells with a specific role - nerve cells, liver cells, muscle
cells - and that role is fixed.
However,
stem cells can become any other type of cell, and they have become a major
field of research in medicine for their potential to regenerate the body.
Embryos are
one, ethically charged, source of stem cells. Nobel prize winning research also
showed that skin cells could be "genetically reprogrammed" to become
stem cells (termed induced pluripotent stem cells).
Acid bath
Now a study
shows that shocking blood cells with acid could also trigger the transformation
into stem cells - this time termed STAP (stimulus-triggered acquisition of
pluripotency) cells.
Dr Haruko
Obokata, from the Riken Centre for Developmental Biology in Japan, said she was
"really surprised" that cells could respond to their environment in
this way.
She added:
"It's exciting to think about the new possibilities these findings offer
us, not only in regenerative medicine, but cancer as well."
The
breakthrough was achieved in mouse blood cells, but research is now taking
place to achieve the same results with human blood.
Chris
Mason, professor of regenerative medicine at University College London, said if
it also works in humans then "the age of personalised medicine would have
finally arrived."
He told the
BBC: "I thought - 'my God that's a game changer!' It's a very exciting,
but surprise, finding.
"It
looks a bit too good to be true, but the number of experts who have reviewed
and checked this, I'm sure that it is.
"If
this works in people as well as it does in mice, it looks faster, cheaper and
possibly safer than other cell reprogramming technologies - personalised
reprogrammed cell therapies may now be viable."
For
age-related macular degeneration, which causes sight loss, it takes 10 months
to go from a patient's skin sample to a therapy that could be injected into
their eye -and at huge cost.
Prof Mason
said weeks could be knocked off that time which would save money, as would
cheaper components.
'Revolutionary'
The finding
has been described as "remarkable" by the Medical Research Council's
Prof Robin Lovell-Badge and as "a major scientific discovery" by Dr
Dusko Ilic, a reader in stem cell science at Kings College London.
Dr Ilic
added: "The approach is indeed revolutionary.
"It
will make a fundamental change in how scientists perceive the interplay of
environment and genome."
But he
added: "It does not bring stem cell-based therapy closer. We will need to
use the same precautions for the cells generated in this way as for the cells
isolated from embryos or reprogrammed with a standard method."
And Prof
Lovell-Badge said: "It is going to be a while before the nature of these
cells are understood, and whether they might prove to be useful for developing
therapies, but the really intriguing thing to discover will be the mechanism
underlying how a low pH shock triggers reprogramming - and why it does not
happen when we eat lemon or vinegar or drink cola?"

“…Yawee,
let's talk about your invention, your most recent one. You described your
guided stem cell protocol as a "go there and stay there"
instructional technology to guide the stem cells directly to where they are
needed. You "instruct" the stem cells to go to a place in the body
and stay there where they can be used. Now, the ones sitting in the chairs today
don't know anything about that. But you do and I do. And you know that you're
either incredibly lucky, over and over, or you're dealing with something else.
Because to guide a stem cell in a "go there and stay there" scenario
is like a Human Being reporting to a city of a billion people, then standing on
the outskirts and locating that one person they are looking for, right away, by
accident! Somehow it works.
Your
"go there and stay there" is a macro program accomplishing an
incredible micro result. How? Trillions, if not hundreds of trillions of DNA
molecules are all identical in the Human body. Somehow they "talk to each
other" instantly. If one DNA molecule senses something, they all do.
Science doesn't know that yet. They may have thought of it, but they don't know
it. There is a mystery here of how DNA does what it does. Somehow it must
communicate, yet there is no process of communication known to your science
that could explain it. But they all "see" the intent of your program
together as one and implement it as one.
We have
told you this before, and we have written books about it. Your DNA has quantum
attributes. It's not a quantum molecule, but it gives quantum instructions. Ah,
but there's more. All the DNA I perceive in your body right now is singular,
with only one allied consciousness. This is because the DNA in the Human body
is in an entangled state with itself. It is quantumly locked in a way that it
works as one benevolent union. This is a quantum physics attribute that is not
yet fully understood and not yet applied to biology. It represents the smart
body, the innate body, and if you want proof of that, it's everywhere!
What do you
know about identical twins? You know that they have the same DNA and that they
are the only Humans on the planet who do. What do you know about studies of
identical twins? You know that they can be on opposite sides of the planet and
both can have the same intuition at the same time about something that's
happening with their family. Now, what does that tell you about their DNA? It's
connected! In fact, it's connected within a particular quantum state. What do
you know about quantumness in DNA? The answer is, almost nothing! So let me
fill you in. It's beautiful. Let me fill you in, because it's going to temper
everything you do from now on. ..”
