Primary Cell Cultures vs Adherent Cell Cultures

Play an AI-generated podcast conversation about this lesson

What is the purpose of using protease/chelator solution in cell culture?

To induce division in connective tissue fibroblasts

To prevent cells from adhering to the culture dish

To remove adherent cells from the culture dish (correct)

To promote the growth of nonadherent cells

What happens if special precautions are not taken when isolating other types of cells from rapidly dividing connective tissue fibroblasts?

Other cells start dividing more rapidly

Special precautions are unnecessary

Connective tissue fibroblasts die off

Connective tissue fibroblasts become the predominant cell type (correct)

Why do certain cells from blood, spleen, or bone marrow grow well even though they adhere poorly to the culture dish?

Because they are held in suspension in the body's fluids (correct)

Because they are highly resistant to protease/chelator solutions

Because they require special nutrients to grow

Because they are non-dividing cells
