It was awesome.

But it's taken a long time to get there.

That's the good news.

And so indeed, there are times when we can find ingredients that are bad.

One that has just happened in the last few months is the successful approval of a drug for cystic fibrosis.

I guess in plural it's scrotal, like medium and media.

Well basically that means that this protein is changing from the sensitive cell to the resistant cell.

liver, gall bladder, small intestine, and large intestine, also known as your colon.

But on my left retina there is a bump, which is marked there by the red arrow.

Embryonic stem cells have occupied center stage, chiefly because of their pluripotency that is their ease in differentiating into a variety of different cell types.

May I have an ice bag?

Let's make it concrete.

And the cells that have a haploid number of chromosomes are our gametes, which are sperm cells for men, and ova, or egg cells for women.

So certain genes are expressed in certain parts of the body, but every one of your body cells, and we call those somatic cells, and we'll separate those from the sex sells or the germs that we'll talk about later.

although he suffered from severe pseudofolliculitis nuchae.

In the case of a male, these would be sperm cells.

That really creeped us out.

I will not bring it to the scrotal.

disabling, reversing cell cycle inhibitors.

I turned to my mom and dad to tell them we needed to go home, and at that moment, you came out of the Student Union building wearing the stupidest hat I have ever seen in my life. (Laughter)

SR So what do you think, Xu?

I go in, tail comes off.

Let me write this down in a vibrant color.

So let's say those are the germ cells.

The whole process of differentiation is actually fascinating, and we'll talk a lot more about that when we talk about stem cells, embryonic stem cells, and maybe we'll even talk about the debate of it.

Please bring an ice bag.

Isn't that a gas?

So why should you care? Bone marrow is a very rich source of adult stem cells.

They discovered that adult cells, taken from you and me, could be reprogrammed back into embryonic like cells, which they termed IPS cells, or induced pluripotent stem cells.

living organisms have been relatively simple single cells.

So, we took the red cells you see the red cells are surrounded by blue, other cells that squeeze them, and behind it is material that people thought was mainly inert, and it was just having a structure to keep the shape, and so we first photographed it with the electron microscope years and years ago, and you see this cell is actually quite pretty.

Memory cells generated by the HlV vaccine are activated when they learn

But adult stem cells are not embryonic stem cells.

And these are some of the cells that might be overactive in disorders such as epilepsy.

Within 10 years of the first gallbladder surgeries being done laparoscopically, a majority of gallbladder surgeries were being done laparoscopically truly a pretty big revolution.

And one of the the cutting edge areas that we're just incredibly excited about is stem cell therapy.

In a female, they would be involved in the ovaries.

Throw a drug at it, and resistant cells will grow back.

And some of our investigative teams have demonstrated that female stem cells and this is in animals and increasingly we're showing this in humans that female stem cells, when put even into a male body, do better than male stem cells going into a male body.

Early Embryo

You can think of channelrhodopsin as a sort of light sensitive switch that can be artificially installed in brain cells so that now we can use that switch to activate or inactivate the brain cell simply by clicking it, and in this case we click it on with pulses of light.

So if this was happening, your memories could start by place cells activating each other via these dense interconnections and then reactivating boundary cells to create the spatial structure of the scene around your viewpoint.

You probably know, if you've been paying attention to some of the science literature that you can now take a skin cell and encourage it to become a liver cell or a heart cell or a kidney cell or a brain cell for any of us.

Not to worry. It's a noninvasive extraction of cells.

And you can do that you can tweak the viruses so they hit just some cells and not others.
