Հիմնականում ինչի մասին խոսում ենք, ամենաքիչը մեր վիդեոներում վերաբերում են էուկարիոտներին

I believe matter begets life

Think of DNA, cells, galaxies, fruits,

Այստեղ այլ բաներ կա, որ կարող ենք խոսել

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

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.

We're taking off.

Over 40 years ago, I was cloning stem cells and one of the first experiments just so blew my mind

Ահա, թե ինչ է անում լիզոսոմը

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

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

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.

I'll nicely demonstrate that for you. (Laughter)

It's also simpler when you go into eukaryotes like ourselves you can just pop out the nucleus and pop in another one, and that's what you've all heard about with cloning.

And we know staph can do amazing things.

And this whole thing right here, the combination of the water and the sugar molecules, we call a solution.

And what MyoD essentially does is, it causes cells to differentiate into muscle cells.

So here's two sort of canonical neurons from a vertebrate and an invertebrate, a human pyramidal neuron from Ramon y Cajal, and another cell to the right, a non spiking interneuron, and this is the work of Alan Watson and Malcolm Burrows many years ago, and Malcolm Burrows came up with a pretty interesting idea based on the fact that this neuron from a locust does not fire action potentials.

Animal bodies are made up of cells.

It can actually make itself glow.

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

Fat derived stem cells are adult stem 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.

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

Cell division

Cell radius

They were developed in Japan pretty recently.

From Conception to Birth Oocyte

Fuel cells.

And also these are signals that go awry in disorders such as addiction.

'In what way have we been using the influence of society, which is probably the most powerful force in human psychology?' 1967 Influence of Biological Environments A Stem Cell Experiment

Ceramides. They act as a signaling molecule in skin.

In these cells, the mission is to move blood around their body.

And that's your ancestor.

So if I start off with a diploid cell, and that's my diploid cell right there, this would be a germ cell.

This actually shows the scaffold.

The centrosomes have gone to opposite sides of the cell itself.

So this is my body cells.

This is the whole cell.

They get pulled apart even more.

And it's a beautifully complex neuron.

I shouldn't say cell wall.
