When cancer cells are crowded by surrounding cells, the cancer cell becomes spherical and they can still go through cell division, whether this is true or false.
00:11
So for this question, the correct answer is true.
00:16
So what happened is usually when we have cells, they have this feature we call contact inhibition.
00:30
So by definition, it means that usually when the cell proliferate, they actually form a confluent monolayer forms.
00:40
So you can see this is a single cell.
00:42
So they form a single layer.
00:43
So when they contact each other, they stop proliferating.
00:53
So basically, they flatten out and they spread out.
00:57
Then once they have contact with another cell, this is a regulation to the cell cycle and they actually tell the cell to stop proliferating because there is outer space.
01:09
So this is what we call contact inhibition...
