This video describes the technique of generating three-dimensional spheroids via the hanging drop method using melanoma cells. The generated in vitro three-dimensional (3D) organotypic melanoma spheroid model can portray the in vivo architecture of malignant melanoma and may give insights into intra-tumoral interactions.
Protocol
1. Generation of 3D Melanoma Spheroids Via the Hanging Drop Method Culture melanoma cells (e.g., 451-LU, or any melanoma cell line of interest) according to general protocols, using RPMI containing 10% FCS. To generate melanoma spheroids of similar size and quality, wash the melanoma cells in PBS, add 5 mL of 1x Trypsin-EDTA in PBS to the cells in a T175 cell culture flask, and incubate for 3 – 5 min at room temperature (RT). Neutralize the Trypsin by a…
