Ceramides. They act as a signaling molecule in skin.

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.

And, there are other frequently dividing cells in your body

And if this continues the toe cell would die.

That turns out to be a big deal because now you can take, not just mouse cells, but you can human skin cells and turn them into human stem cells.

And then what they did in October is they took skin cells, turned them into stem cells and began to turn them into liver cells.

So the membrane dissolves.

And this is the perfect storm for forming a pimple.

Mitosis occurs in pretty much all of our somatic cells as our skin cells replicate, and our hair cells and all the tissue in our body as it duplicates itself, it goes through mitosis.

It has not experienced cytokinesis, which we will talk about in a few moments, but that's the process of the actual cytoplasm of the cell being split into two different cells.

And, of course, there's the entire cytoplasm in the rest of the cell.

Բայց ռիբոսոմները ուղղակի պտտվում են, եթե նրանք ազատ ռիբոսոմներ են, հետո այդ սպիտակուցները, որոնք արտադրվեցին ռիբոսոմի վրա, կպտտվեն այստեղ բջջի հեղուկ մասսայում դա մենք կոչում ենք ցիտոպլազմա

One can say, OK, what are we made of?

So that all the cells of your body the skin cells, the cells of your liver, and of your heart, and even of your ear, those cells know, at a fundamental molecular level, whether they are XX or XY.

And instead of getting normal perception, you're getting an anarchic, convulsive stimulation, or release, of all of these visual cells in the inferotemporal cortex.

You place the muscle cells on the outside.

By the end of telophase in mitosis, you also have this process of cytokinesis, where this cleavage furrow forms and deepens, deepens, deepens until the cytoplasm is actually split into two separate cells.

It's important if you try to model this.

And we know staph can do amazing things.

He has a nuclear membrane, and, of course, it has cytoplasm around it.

It can actually make itself glow.

A couple of years ago, the Lasker Prize was awarded to the scientist Shinya Yamanaka for his research in which he took an adult skin cell, a fibroblast, and by manipulating just four genes, he induced that cell to revert to a pluripotential stem cell a cell potentially capable of becoming any cell in your body.

Then a repressor protein that blocks the operating cells.

So in a male, you have some germ cells, so some of these cells turn into germ cells.

Եվ ահա սպիտակուցները կմղվեն ներս դեպի էնդոպլազմային ցանց

Each one plays a particular role a heart cell, a muscle cell, a brain cell.

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.

The observation that stem cells, as master cells, could give rise to a whole variety of different cell types heart cells, liver cells, pancreatic islet cells captured the attention of the media and the imagination of the public.

Եկեք դա նշեմ բջջային թաղանթ

This actually shows the scaffold.

You already saw the work by Tony Atala on TED, but this ability to start filling things like inkjet cartridges with cells are allowing us to print skin, organs and a whole series of other body parts.

No thanks, I'd actually rather store this energy.

Fat derived stem cells are adult stem cells.

This is fascinating. You probably know, some of you, that cells are continually renewed.

But even now, 2011, there's still certain cells that we just can't grow from the patient.

They're a lot like embryonic stem cells except without the controversy.

So if they have RNA, this RNA can immediately start being used to essentially let's say this is the nucleus of the cell.

Օրինակ իմ լյարդը ենթամիավոր է Սալ ի և դա օրգան է, օրգանոիդը բջջի ենթամիավոր է

Cell division

Cell radius

They were developed in Japan pretty recently.

From Conception to Birth Oocyte

Fuel cells.

We have lots of cells that are not out for themselves anymore.
