Strain Description [Including phenotype, strain background, strain development and suggested control mice]

Phenotype

When the Plxna4tm1Matl allele is homozygous and the Plxna3tm1Matl allele is hemizygous, the phenotype shows Axon guidance defects.


Mammalian Phenotype Terms:(provided by MGI)      Extend all MPTs
      assigned by genotype

The following phenotype information may relate to one or more alleles on a genetic background differing from this MMRRC strain.

        either: (involves: 129P2/OlaHsd * 129S1/Sv * C57BL/6) or (involves: 129P2/OlaHsd * 129S1/Sv * CD-1)
  • nervous system phenotype
    • abnormal axon guidance (MGI Ref ID J:98440)
      • repulsive effect of Sema3A on axon growth from sensory neurons of the dorsal root ganglia and of superior cervical ganglion neurons was eliminated
    • abnormal sensory neuron projections (MGI Ref ID J:98440)
      • starting at E11.5, had severely disrupted peripheral sensory projections, with many axons crossing the dorsal midline to the other side of the body at E12.5
      • peripheral sensory projections exhibited extensive outgrowth and branching as if there were no boundaries for the axons
    • abnormal trigeminal nerve morphology (MGI Ref ID J:98440)
      • severely disorganized and derasciculated ophthalmic, maxillary and mandibular projections at E11.5
      • more fibers of the ophthalmic branch misprojected in different directions, and some even started to invade the eye region at E11.5 and the ophthalmic axon fibers covered the entire face, including the eyes and the fibers were thinner and heavily branched at E12.5 compared to wildtype
    • abnormal trochlear nerve morphology (MGI Ref ID J:98440)
      • severely defasciculated even though individual axons could still be seen leaving the midbrain-hindbrain junction

Health Status Report

Mice recovered from a cryo-archive will have health surveillance performed on recipient females. Health reports will be provided prior to shipment. If you require additional health status information, please email mmrrc@missouri.edu.

Order Request Information

Availability Level

Limited quantities of breeder mice (recovered litter) are available from a cryoarchive; recovered litter usually available to ship in 3 to 4 months.

Conditions of Distribution [Including applicable technology transfer agreements]

Distribution of this strain requires submission of the MMRRC Conditions of Use (COU). A link to the COU web form will be provided via email after an order has been placed; the form should be completed then or the email forwarded to your institutional official for completion.

The donor or their institution limits the distribution to non-profit institutions only.

Fees

Additional charges may apply for any special requests. Shipping costs are in addition to the basic distribution/resuscitation fees. Information on shipping costs and any additional charges will be provided by the supplying MMRRC facility.

1 The distribution fee covers the expense of resuscitating mice from the cryo-archive; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.

2 An aliquot is one straw or vial with sufficient sperm to recover at least one litter of mice, as per provided protocols, when performed at the MMRRC facility. The MMRRC makes no guarantee concerning the success of these procedures when performed outside the MMRRC facilities.

3 An aliquot contains a sufficient number of embryos (in one or more vials and based on the transfer success rate of the MMRRC facility) to transfer to at least two recipients. The MMRRC makes no guarantee concerning embryo transfer success experienced in the recipient investigator's laboratory. Neither gender nor genotype ratios are guaranteed.
