Metaplasia (Greek change in form ) is the reversible replacement of one differentiated cell type with another mature differentiated cell type.

A cell may stay in this state for several days, and then either die or irrevocably differentiate into a mature, fully differentiated plasma cell.

The B cell and T cell numbers are within normal limits.

The B cell will also take this guy into the cell.

It won't bind to this B cell or this B cell because they have different sequences here, but it binds to this B cell and then that starts the activation process.

So this is a particular B cell.

So a B cell will also present the antigen.

And what made that interesting is that every B cell has its own specific or they have membrane bound antibodies, but for each B cell, the membrane bound antibodies on each specific B cell had its own variable portion.

So this B cell it'll be variable right like that.

So this whole thing gets engulfed by the B cell.

She's so mature.

So if we have a B cell that's a good color.

This different B cell is going to have different variable portions.

She looked surprisingly mature

Another B cell will bump into this virus and it won't attach.

The interesting thing is that from one B cell to another B cell, they have a variable part on this antibody that could take on a bunch of different forms.

But let's say some new bacteria and just some part of its surface just happens to bind to only this B cell because this B cell has just the right combination.

And let's say the virus just happens to bond to this B cell.

She is more... more mature.

Wellbred and mature

Once exposed, it either becomes a memory B cell or a plasma cell that secretes antibodies specific to the antigen that was originally bound.

When I did the other B cell example, I said we're dealing with viruses.

So some part of his surface binds just to that B cell right there.

And here is the limitation adult stem cells are mature cells, and, like mature human beings, these cells are more restricted in their thought and more restricted in their behavior and are unable to give rise to the wide variety of specialized cell types, as embryonic stem cells can .

You can tell it's mature bone.

mature actresses to continue playing roles

I have always liked mature women.

We progress and mature by fault.

Mature persons obtain the right to vote.

People mature slowly through meeting other people.

Saying something mature for once and all.

However, as they mature, they become female.

And our PC version became quite mature.

B vitamins are a class of water soluble vitamins that play important roles in cell metabolism.

Let's say we have a B cell and it's got its membrane bound antibody on it.

But the interesting thing is that the B cell will also do what the phagocytes do.

This time we got some more mature members.

That's something a bit more mature and sophisticated...

One very young, one a little more mature.

Your skin cell is really useless without a heart cell, muscle cell, a brain cell and so on.

And young full breasted ( mature ) maidens of equal age

And young full breasted ( mature ) maidens of equal age

The ground of men is very stubborn to mature.

Cell damage and cell death then result.
