What's a Confluent Monolayer?

For cells that grow as a monolayer, confluence is defined as the percentage of the culture vessel surface area that appears covered by a layer of cells when observed by microscopy. For example, 50% confluency means half of the surface of the culture dish, flask, etc. is covered in cells.

What is a confluent monolayer?

Confluent monolayer refers to cells in tissue culture, e.g. epithelial cells, which form a cohesive sheet comprising of a single cell layer filling the entire surface area of the bottom of the culture dish. Cells have then reached confluence. Desmosomes.

How do you know if a cell is confluent?

50%: An easy estimation is for 50 % confluent cells since the area covered by the cells looks similar to the area that is not occupied by the cells. 100%: Another easy estimation is for cells that are 100% confluent since you will not see any space in between the cells.
