So often, we’re told to scratch beneath the surface when evaluating our options, and think long term.
But when you’re working to achieve physiological conditions for your cell cultures, the surface is exactly where you want your focus to be. The surface used to cultivate cancer cells, for example, has a direct effect on the formation and proliferation of cancer spheroids. And when you’re working in cancer research, it can make all the difference in generating meaningful results and identifying effective treatments.
But how do you best encourage spheroid formation in your cell cultures?

2D versus 3D
The two-dimensional monolayer cell culture is well known, and it results in a comforting uniformity—cells exposed to consistent concentrations of oxygen and nutrients, relatively uniform growth rate, and equal exposure to extracellular signals. None of this, however, replicates the in vivo growth environment of tumors, whose surfaces and hypoxic cores demonstrate distinct growth patterns.
Cancer spheroids better model tumor progression and are a better tool for anti-cancer drug screening.
The ideal spheroid conditions
We have done a lot of testing to identify conditions ideal to the spontaneous formation of spheroids. Working with an ultra low-binding surface coated with a neutrally charged hydrophilic polymer, we saw excellent spheroid growth in test after test of cancer lines, including HeLa, MCF-7, and HepG2.
Accordingly, we’ve developed a new line of ultra low-binding flasks, dishes, multi-dishes, and plates with surface characteristics that specifically encourage the growth of reproducible spheroids. You can learn more about this innovative line of cultureware, designed to help advance your cancer research.
