Former Names BF2(+/-lacZ) (Changed: 15-DEC-04 ) Type Congenic; Mutant Strain; Targeted Mutation; Additional information on Genetically Engineered and Mutant Mice. Visit our online Nomenclature tutorial. Additional information on Congenic nomenclature. Species laboratory mouse Generation N?pN1p (25-APR-04) Donating Investigator Eseng Lai, Merck Development
A targeting vector containing lacZ, neomycin resistance and herpes simplex virus thymidine kinase genes was used to disrupt most of the coding sequence downstream of the transcription initiation site. The construct was electroporated into 129S1/Sv-p+ Tyr+ KitlSl-J/+ derived CJ7 embryonic stem (ES) cells. Correctly targeted ES cells were injected into C57BL/6 blastocysts.

The following phenotype information may relate to a genetic background differing from this JAX® Mice strain.
Foxd1tm1Lai/Foxd1tm1Lai
either: (involves: 129S1/Sv * 129X1/SvJ) or (involves: 129S1/Sv * C57BL/6)
- lethality-prenatal/perinatal
- neonatal lethality (MGI Ref ID J:33767)
- homozygous mutant mice survive to term but die within 24 hours after birth
- behavior/neurological phenotype
- abnormal eating behavior (MGI Ref ID J:33767)
- although initially indistinguishable from wild-type mice, homozygous mutant mice fail to feed
- endocrine/exocrine gland phenotype
- small adrenal glands (MGI Ref ID J:33767)
- the mutant adrenal glands are approximately one-half the wild-type size and separated from the kidneys
- renal/urinary system phenotype
- *normal* renal/urinary system phenotype (MGI Ref ID J:33767)
- the ovaries, testis, and bladder of homozygous mutant mice appear morphologically normal
- molecular marker analysis indicated that induction and condensation of the nephrogenic mesenchyme occurs normally
- in contrast to the observed abnormalities in nephrogenesis and the morphogenesis of the renal collecting system, the stromal cell component appears morphologically normal
- abnormal kidney morphology (MGI Ref ID J:33767)
- the kidneys of homozygous mutant mice are fused longitudinally through apposition of the capsule, and rotated 90 degrees ventrally
- histological analysis revealed a decrease in the number of differentiated nephrons (25% of the wild-type number) and reduced, abnormal branching of the renal collecting system (8- to 16-fold reduction in the number of branches at E14.5)
- the total number of glomeruli in kidneys of homozygous mutant mice is approximately 7% of the wild-type number
- abnormal kidney development (MGI Ref ID J:33767)
- by E14.5, when the developing kidney usually subdivides into two distinct areas (the cortical zone and a nephrogenic zone), homozygous mutant kidneys have no distinct nephrogenic zone and display abnormally large mesenchymal aggregations (5-20 cell layers thick) in the cortical and the medullary regions of the mutant kidney
- these mesenchymal condensations suggest that the differentiation of the metanephric mesenchyme to nephrons is inhibited
- small kidney (MGI Ref ID J:33767)
- at E12.5, the homozygous mutant and wild-type kidneys are identical in size
- at E14.5, the homozygous mutant kidneys are approximately one-half the wild-type size; at term, they are less than one-third the size of wild-type kidneys
- short ureter (MGI Ref ID J:33767)
- in homozygous mutant mice, the ureter is shorter (approximately one-half the wild-type length, but of normal diameter) and located on the ventral side of the kidneys
- respiratory system phenotype
- abnormal respiration (MGI Ref ID J:33767)
- several hours after birth, homozygous mutant mice develop a fast respiratory rate and accumulate air in their stomach
- vision/eye phenotype
- abnormal retina morphology (MGI Ref ID J:33767)
- homozygous mutant mice display mild retinal abnormalities, including abnormal retinotectal projections
- nervous system phenotype
- abnormal forebrain morphology (MGI Ref ID J:33767)
- homozygous mutant mice display mild forebrain abnormalities (no details are provided)
