Description

Somitogenesis is disturbed in these Notch1 deficient mice.

Detailed description

In these Notch1 deficient mice, somitogenesis is disturbed and there is a probable defect in chorio-allantoic connection. Homozygotes die at embryonic day 9.

In an attempt to offer alleles on well-characterized or multiple genetic backgrounds, alleles are frequently moved to a genetic background different from that on which an allele was first characterized. This is the case for the strain above. It should be noted that the phenotype could vary from that originally described. We will modify the strain description if necessary as published results become available.

Development

The targeting vector used deleted a large portion of the Notch1 gene.
