Some imbecile. What a marvellous body...

Let me write those words down.

And this mass of cells, we can start calling it, this right here, this is referred to as the morula.

And the other side is a mulberry.

In the farms and fields... there are always frogs, grasshoppers, mice, moles... persimmons and mulberries.

And so, just so you know a couple of the labels that are involved here, if we're dealing with a mammalian organism, and we are mammals, we call this thing that the morula turned into is a zygote, then a morula, then the cells of the morula started to differentiate into the trophoblast, or kind of the outside cells, and then the embryoblast.

The zygote happens or gets created and starts splitting up the morula, and then it keeps splitting and it differentiates into the blastocyst, and then this is where the stem cells are.

If you had faith as big as a mustard seed, you could say to this tree Pull yourself up by the roots and plant yourself in the sea, and it would obey you.

But the moral controversy surrounding embryonic stem cells the fact that these cells are derived from five day old human embryos has encouraged research into other types of stem cells.

And actually, it comes from the word for mulberry because it looks like a mulberry.

In the old days... ...many courtesans had great learning... ...and lived like princesses.

It's often going to be a power of two, because these cells, at least in the initial stages are all duplicating all at once, and then you have this morula.

Now, it can be a very confusing topic, because a lot of times in a lot of books on biology, you'll say, hey, you go from the morula to the blastula or the blastosphere stage.
