Hello everybody :wave:,

I have the following experimental setup and would need advise on how to evaluate the data.

I extracted monocytes from human blood donors (around 10) and cultured them in three different conditions. After the culturing period, I want to compare their expression for certain surface markers.
Which statistical test is correct?

The donors are independent from each other (different person each time), but are the cultured cells matched/repeated measures?

Thank you.
