growth of cancer cells

Post by Arthur » Sat Aug 19, 2006 5:35 pm

Hi,

Do human cancer cells in vitro grow (divide) slower if they are separated from neighbour cells? "Cell culture" do always mean that cells are not separated from neighbour cells, right?

Every cell, including cancer cell, needs nutrients to support their life. In vivo, they release some cytokin e.g. TGF (tumour growth factor) and TAF (tumour angiogenesis factor) to facilitate new blood vessels which bring nutrients by the plasma. In vivo, this condition never happens, so we must prvided adequate nutrient (external supply) to culture hem and make them survive for such time.
