Overview

Also Known As: src-

These Src knock-out mice exhibit a deficiency in bone remodeling, indicating impaired osteoclast function, and developed osteopetrosis. They are suitable for use in applications related to the study of the physiological role of the Rous sarcoma oncogene.

Detailed Description

Mice homozygous for the Src^tm1Sor targeted mutation display osteopetrosis. Homozygous mutant mice are approximately one-third the size of normal wildtype siblings. Incisors fail to erupt. In general, long bones are shorter in length and show a partial absence of bone marrow. Src has been implicated in development, but its role may be masked by other tyrosine kinases. No overt phenotype is found in brain or platelets, where it is most highly expressed. Mice heterozygous for the Src^tm1Sor mutation have no apparent abnormalities.

Control Suggestions

Wildtype mice from the colony or B6129SF2 mice (Stock No. 101045) may be used as controls. The B6129SF2 mice only provide an approximate genetic match to this B6;129 mixed background.

Mammalian Phenotype Terms by Genotype

The following phenotype information is associated with a similar, but not exact match to this JAX^® Mice strain

Genotype: Src^tm1Sor/Src^tm1Sor
B6.129S7-Src/J

embryo phenotype

abnormal decidualization
- however, prolonged treatment with E2+P4 for 10 days elicited both functional and morphological decidualization even in homozygous mutant ESCs
- ild-type and heterozygous females, as determined by uterine histology and uterine weight changes
- in vitro, endometrial stromal cells (ESCs) from wild-type mice became morphologically decidualized when cultured in the presence of E2+P4 for 5 days, whereas ESCs from female homozygotes remained morphologically unchanged
- ovariectomized female homozygotes treated with a low dose of estrogen (E2) and a high dose of progesterone (P4), followed by mechanical stimulation of the left uterine horn, showed little or no detectable decidual responses relative to similarly-treated wild-type and heterozygous females, as determined by uterine histology and uterine weight changes

reproductive system phenotype

abnormal decidualization
- however, prolonged treatment with E2+P4 for 10 days elicited both functional and morphological decidualization even in homozygous mutant ESCs
- ild-type and heterozygous females, as determined by uterine histology and uterine weight changes
- in vitro, endometrial stromal cells (ESCs) from wild-type mice became morphologically decidualized when cultured in the presence of E2+P4 for 5 days, whereas ESCs from female homozygotes remained morphologically unchanged
- ovariectomized female homozygotes treated with a low dose of estrogen (E2) and a high dose of progesterone (P4), followed by mechanical stimulation of the left uterine horn, showed little or no detectable decidual responses relative to similarly-treated wild-type and heterozygous females, as determined by uterine histology and uterine weight changes

female infertility
- female homozygotes are severely subfertile or infertile, partly due to impaired decidualization resulting from the loss of maternal function in endometrial stromal cells

The following phenotype relates to a compound genotype created using this strain

Genotype: Src^tm1Sor/Src^tm1Sor
either: 129S7/SvEvBrd-Src or (involves: 129S7/SvEvBrd * C57BL/6J)

craniofacial phenotype

abnormal craniofacial bone morphology
- facial bones are thickened by fibrous and osseous tissue proliferation and lack of bone resorbtion
- smaller airway lumina are present due to abnormal facial bone morphology

abnormal head shape
- mice have a slightly domed head

abnormal tooth eruption
- some molar teeth show partial eruption, but are crowded by osseous growth of the facial bones

absent incisors
- incisor teeth are well developed, but fail to erupt through the gum
- incisors are absent at 3 weeks of age

broad face
- mice have a broad face

failure of tooth eruption
- incisor teeth are well developed, but fail to erupt through the gum

immune system phenotype

increased inflammatory response

mortality/aging

postnatal lethality, incomplete penetrance

We will fulfill your order by providing at least two carriers for each strain ordered. The total number, sex, and genotypes provided will vary, although typically 8 or more animals are provided. Please check genotypes which will be recovered. While the genotypes of all animals produced will be communicated to you prior to scheduling shipment, the genotypes of animals provided may not reflect the mating scheme and genotypes described in the strain description. Animals are typically ready to ship in 11-14 weeks. If a second recovery is required to produce the minimum number of animals, then delivery time would increase to approximately 25 weeks. If we fail to produce animals of the correct genotype, you will not be charged. We cannot guarantee the reproductive success of mice shipped to your facility. If the mice are lost after the first three days (post-arrival) or do not produce progeny at your facility, a new order and fee will be necessary.

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project.
