Publication number: 20150047061Abstract: Genetically modified mice comprising a nucleic acid sequence encoding a human M-CSF protein are provided. Also provided are genetically modified mice comprising a nucleic acid sequence encoding a human M-CSF protein that have been engrafted with human cells such as human hematopoietic cells, and methods for making such engrafted mice. These mice find use in a number of applications, such as in modeling human immune disease and pathogen infection; in in vivo screens for agents that modulate hematopoietic cell development and/or activity, e.g. in a healthy or a diseased state; in in vivo screens for agents that are toxic to hematopoietic cells; in in vivo screens for agents that prevent against, mitigate, or reverse the toxic effects of toxic agents on hematopoietic cells; in in vivo screens of human hematopoietic cells from an individual to predict the responsiveness of an individual to a disease therapy, etc.Type: ApplicationFiled: August 26, 2014Publication date: February 12, 2015Inventors: Andrew J. Murphy, Sean Stevens, Chozhavendan Rathinam, Elizabeth Eynon, Markus Manz, Richard Flavell, George D. Yancopoulos
