Strain development
Strain descriptionMsi1 deficient miceC57BL/6J background Msi1 deficient mice frequently died of obstructive hydrocephalus within a couple of month with aberrant cell proliferation around cerebral aqueduct. (Sakakibara S et al. Proc Natl Acad Sci USA. 2002) Both male and female are infertile because of the early death of hydrocephalus.On the other hand, CD-1 (ICR) background Msi1 deficient mice survive to adult without gross anatomical phenotype. Since both male and female are fertile, it is possible to mate between Msi1 null mice. (Unpublished data)
