Can we actually pinpoint the molecular changes in a tumor so that we can actually go after it in a smart way and deliver drugs that might wipe out exactly the
cells
that we want to?
In a campfire, when the logs are heated to their ignition temperature, the walls of their
cells
decompose, releasing sugars and other molecules into the air.
And where the fungal
cells
interact with the root cells, there's a trade of carbon for nutrients, and that fungus gets those nutrients by growing through the soil and coating every soil particle.
In a single cubic inch of soil, there can be more than eight miles of these
cells.
I believe matter begets life; life becomes single cells; single
cells
become strings; strings become chains; chains network.
So big, shiny black solar
cells
on our roof mean our electricity bill rarely exceeds more than five bucks in a month.
It causes fluid to flow from the
cells
that line our intestine into the lumen, the internal chamber of our intestine, and then that fluid goes the only way it can, which is out the other end.
We don't really know that much about
cells.
We don't know why some
cells
want to do one repair pathway and some
cells
would rather do the other.
And those sugar molecules are injected into these patients by the billions, and they're going all over the body looking for
cells
that are hungry for sugar.
For the first time it allowed us to look into someone's body without picking up each and every one of the
cells
and putting them under the microscope, but in a noninvasive way allowing us to look into someone's body and ask, "Hey, has the cancer metastasized?
Can anyone guess how many cancer
cells
are in any one of these tumors?
So it's about 100 million cancer cells, and let me make sure that this number sunk in.
In each and every one of these small little blips that you're seeing on the image, there needs to be at least 100 million cancer
cells
in order for it to be detected.
This is in fact an incredibly large number, because what we really need in order to pick up something early enough to do something about it, to do something meaningful about it, well, we need to pick up tumors that are a thousand
cells
in size, and ideally just a handful of
cells
in size.
Because now you need to decide, should I stop here and let this patient go, risking that there might be some leftover cancer
cells
behind that I just couldn't see, or should I take away some extra margins, typically about an inch or so around the tumor just to be sure that I removed everything?
Let's program them to look for cancer
cells.
Those leftover tumors, even if it's just a handful of cells, they will grow to recur the tumor, for the tumor to come back.
And I think where medical imaging is heading to is the ability to look into the human body and actually see each and every one of these
cells
separately.
The ability like this would allow us to actually pick up tumors way, way earlier in the process, way before it's 100 million
cells
inside, so we can actually do something about it.
An ability to see each and every one of the
cells
might also allow us to ask insightful questions.
So in the lab, we are now getting to a point where we can actually start asking these cancer
cells
real questions, like, for example, are you responding to the treatment we are giving you or not?
At every heartbeat, a higher blood pressure literally compacts millions of red blood
cells
into massive trains of oxygen that quickly flow throughout our body.
And the tiny space inside our red blood
cells
is not wasted, either.
The reason blood is so incredibly efficient is that our red blood
cells
are not dedicated to specific organs or tissues; otherwise, we would probably have traffic jams in our veins.
They're shared by all the
cells
of our body.
And because our network is so extensive, each one of our 37 trillion
cells
gets its own deliveries of oxygen precisely when it needs them.
Red blood
cells
are not flowing in lanes.
And oxygen deprivation in the retinal
cells
impairs their ability to process light, causing greyed out vision or temporary blindness.
And one of the things that we've been doing is trying to figure out how to reprogram
cells.
