An international project to develop a large, globally accessible bank of new cancer cell culture models for the research community was launched by the National Cancer Institute; Cancer Research UK in London; the Wellcome Trust Sanger Institute in Cambridge, U.K.; and the foundation Hubrecht Organoid Technology in Utrecht, the Netherlands. The push is called the Human Cancer Models Initiative, designed to bring together expertise from around the world to make about 1,000 cancer cell models. Using new techniques, scientists will make models that will better resemble the tissue architecture and complexity of human tumors than the cell lines used now.
