This topic addresses the different types of signaling between cells.
00:07
Now, in this case, direct intercellular signaling is addressed.
00:17
Direct intercellular signaling means essentially the cells are joined together.
00:24
The signal goes directly from the cytoplasma 1 to the cytoplasm of another.
00:31
So it doesn't even need to be sending a signal outside of the cell, so to speak.
00:38
It goes directly from one to the other.
00:41
Contact dependent sounds the same, but really it's not, because in this case, the signal is being sent outside the cell.
00:55
It's just being sent only to cells that are directly touching, the cell sending the signal.
01:16
So the signal is being sent from basically the cell membrane of the cell to another cell membrane to the cell.
01:27
It's not directly joined to the cell, like it doesn't have a tunnel in between them, like a gap junction or a plasmata, but it is directly touching the cell.
01:40
Autocrine signaling gives you a kind of a tip off here with the word auto.
01:58
Auto means self.
02:02
This is the one type of case where it's going to signal itself as well as any neighboring cells in the proximity, as opposed to paracrine signaling, which again is going to sound similar in that the signal...
