    摘要: 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.

    摘要: A method for engineering and utilizing large DNA vectors to target, via homologous recombination, and modify, in any desirable fashion, endogenous genes and chromosomal loci in eukaryotic cells. These large DNA targeting vectors for eukaryotic cells, termed LTVECs, are derived from fragments of cloned genomic DNA larger than those typically used by other approaches intended to perform homologous targeting in eukaryotic cells. Also provided is a rapid and convenient method of detecting eukaryotic cells in which the LTVEC has correctly targeted and modified the desired endogenous gene(s) or chromosomal locus (loci) as well as the use of these cells to generate organisms bearing the genetic modification.
