Abstract:

Mouse models play an irreplaceable role in the in vivo research of human gastric cancer. In this study, we developed a novel human Gastric tissue-derived Orthotopic and Metastatic (GOM) mouse model of human gastric cancer, in which the human normal gastric tissues were implanted subcutaneously into immunodeficient mice to create a human gastric microenvironment. Then, human gastric cancer cells were injected into the implants. GOM model could mimic the interactions between human gastric microenvironment and human gastric cancer cells, which help exhibit the real characteristics of tumor cells, and finally mimic the clinical-like tumor proliferation and metastases of human beings.

Mouse Models of Cancer Study

Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...
