A new method for the three-dimensional in vitro growth of human cancer cells.
A method has been developed which allows, for the first time, the in vitro growth of human tumor cells in calcium alginate gel microcapsules. The three-dimensional matrix is permeable to macromolecules of at least 200 000 molecular weight (MW) (e.g., carcinoembryonic antigen) and provides an environment for organized growth and differentiation more comparable to in vivo growth than monolayer culture. This inexpensive, nondestructive procedure allows studies of morphological, biochemical and immunochemical parameters of human tumor cells within a single model.
