Cover Story: Although 2D in vitro cancer cell cultures have been used for decades to investigate antitumoral treatments, their use presents many drawbacks, including a poor resemblance of in vivo tumors. To mitigate these drawbacks, 3D culture models have emerged as a more representative alternative that more closely resembles solid tumors in their architecture and resistance to chemotherapeutic drugs. Additionally, they create a more physiological environment for the study of immune cell invasion and migration. In our paper, we describe a fast and cost-effective protocol for the generation of 3D spheroids. Using this protocol, spheroids of different human cancer cell lines can be obtained and characterized based on their morphology, viability, and expression of specific markers. View this paper
