                                             SECTION B - PROJECT DESCRIPTION


1.    PROJECT GOALS IN NON-SCIENTIFIC (i.e. “LAY”) LANGUAGE

      The Goal of this study is to produce mice which carry artificially induced genetic material (genes or gene
      fragments) into the mouse genome. The incorporated DNA becomes part of the normal mouse genome and
      allows the study and manipulation of specific genes in a living organism. (Individual Investigators must
      provide specific information about their DNA construct in section A2)


2.    NARRATIVE DESCRIPTION OF ANIMAL PROCEDURES

      Part 1: Pronuclear DNA Injection. Fifteen 21-28 day old weanling female mice are superovulated (SO) for
      each day of injections (max. four days or 60 mice per week). The embryo donors are injected with 2.5 to 5 IU
      pregnant mares' serum gonadotropin (PMSG) each. 44 hours later, 2.5 to 5 IU chorionic gonadotropin (hCG)
      is injected per donor and mated with males from the Transgenic Lab's standing colony of fertile FVB males.

      Pseudopregnancy (PsPg) is stimulated by mating 15 mature female mice for each day of anticipated embryo
      transfers by mating them with males from the Transgenic Laboratory's standing vasectomized male colony.
      Those females with a vaginal plug the next morning will be the recipients for the embryo transfers. (This
      usually produces 5-8 plugged females). The non-plugged females, along with those not used for embryo
      transfer are placed back in the Transgenic/Knockout Laboratory core colony.)

      The donors are sacrificed by C02 narcosis followed by cervical dislocation. The Transgenic laboratory
      (0410B) is equipped with a C02 flow meter and cage top for euthanasia. Embryos are collected from the
      oviducts by flushing with appropriate media and sorted.

      Following the transgenic injections, the embryos are transferred to the oviducts of the PsPg recipient
      females as described in appendix A. The transferred females will be housed in a VAF (viral antibody free)
      colony until birth and weaning of the putative transgenic founder mice.

      Tissue samples will be taken from the pups for analysis indicating successful integration of the transgene in
      the mouse genome. One or more of the following procedures may be used:
      Tail Biopsies for DNA Analysis:
      Standard procedure for mice between 3-4 weeks of age, one tail sample is allowed without anesthesia or
      ligature. (A waiver may be granted for tail snips for genotyping in mice between 21 and 28 days old if
      no more than 1.5mm tissue is taken and if the line requires the extra days after the normal weaning
      age for development. The need for this should be detailed by the individual investigator, in
      consultation with the Core, when completing the application as it must have specific IACUC approval).
      Very little bleeding occurs as the tail tip is cartilage and is not ossified. Older mice are anesthetized and the tail
      is ligated with #1 silk thread about 1.0-1.5 mm from the tip. The tail is clipped with scissors immediately distal
      to the ligature and the mouse placed back into its home cage to recover. Alternatively, the tail is cauterized
      with a cautery pen.
      Ear Biopsies for DNA Analysis: The mouse is restrained by hand and an ear punch biopsy is taken or a small
      snip (2.0mm) of pinna periphery is excised with scissors. No analgesia is necessary for ear biopsies. There is
      no bleeding and pain is momentary similar to ear tagging (or ear punching) for identification.
      Blood samples: Blood samples are taken from Avertin-anaesthetized mice by one of two methods. For
      amounts of 0.25 ml, retro orbital blood sampling is used. For lesser amounts (0.1 ml), the lateral tail vein will
      be nicked and the blood collected.
      The foster mother and non-transgenic pups will be sacrificed by CO2 narcosis followed by cervical
      dislocation, and the positive pups transferred to the investigator's appropriate IACUC protocol for
      breeding and experimental use.


      Part 3: Blastocyst Injection. Ten female 21-28 day old mice are superovulated as in the previous section.

      The embryo donors are sacrificed as in the earlier section at 84 hours post coitus and the uteri dissected out.
      Embryos are collected from the uteri by flushing with the appropriate medium. Following injection of the stem
      cells into 3.5 day blastocysts, embryos are transferred to the uteri of 2.5-day PsPg recipients. Postoperative
      care and recovery is monitored as described in the previous section for oviductal transfers.

        Tissue samples are generally not required to assess integration of the transgene in this procedure. Usually a
        "marker" such as coat color is used to indicate integration of the transgenic embryonic stem cell into the host
        blastocyst and the resulting mouse will be a chimera with two different hair colors. Directed mating is primarily
        used to assess germ line transmission of the transgene.

        In both matings with the donor and VX males, the males are transferred back to their colony for repeat
        utilization. At the end of their useful mating life span (ca. one year), the males are euthanized by CO2
        narcosis.
        Following weaning of the putative transgenic animals, they are transferred the investigator's IACUC protocol.
        The foster mothers are subjected to embryo transfer surgery one time and euthanized by CO 2 narcosis
        following weaning of their transgenic pups

           b.        Number of animals required for the entire study: 124 per construct. Please indicate the
                number of constructs to be used        and adjust the total number of animals accordingly   .
                Please also enter the total number of animals required in section A 5


           c.        How was the number of animals in each group determined?
                Experience has shown that up to 20 donors are required to produce usable numbers fertile embryos
                (150-250) for injections. 50%60% of the embryos generally survive the construct injection, resulting in
                75 to 150 viable embryos. Five recipients are needed to receive 23-30 embryos each. Therefore, the
                number of animals used represents the minimum number of animals required to generate an adequate
                and usable number of transgenic founder mice. Historically, 0.5-1 % of embryos collected will result in
                production of transgenic animals.
                The number of transgenic lines produced by each injection series (injection-day) is widely variable,
                being dependent on the number of positive transgenic animals born. Each transgenic animal will
                become the founder animal of his own line. The number of positive animal produced per injectionday
                can run from zero to an average of 20% of the animals born
                Estimated number of requests for transgenic mouse production originated by investigators in the previous period

           d.        How was the number of repetitions for each group determined?
                The numbers/group represent the number of animals used per injection-day. The number of

             repetitions is the anticipated maximum number of injection-days per year.

There are no means of producing transgene or gene knockout/knockin mice without performing embryo transfer using
surgical procedures. A living recipient is necessary to carry the embryos to term. No alternative methods were
discovered via Medline search.

 7.      Describe the following surgical procedures:
             a. Incision size and location: On flank ~ 1 cm caudal to rib cage and ~1.5 cm lateral to spine
             b. Method of skin closure: Wound clip
             c. General surgical details: The pseudopregnant (PsPg) female is anesthetized with isoflurane (5%
                induction with 3-3.5 % maintenance using a veterinary vaporizer which is recirculation type which
                actively scavenges minimizing potential exposure of personnel to isoflurane gas. Upon full
                anesthesia (lack of toe/foot pinch response – 3-5 minutes), the mouse is placed on her right side
                under a dissection microscope. The incision site is located approximately 1 cm caudal to the rib
                cage and 1.5 cm lateral to the spine. The skin of the prepared surgical site is grasped with small
                forceps and a small incision (0.5 cm) is made in the skin. The incision is moved around over the
                underlying body wall until the ovarian fat pad beneath can be seen and a small incision is made at
                that point, taking care to avoid cutting the vascular and nerve bundles in the muscle. The ovarian
                fat pad is grasped with forceps and gently pulled through the incision, bringing with it the ovary,
                oviducts and proximal portion of the uterus. Exterioization of the reproductive tract is kept to the
                minimum necessary. A small bulldog clamp is attached to the fat pad if necessary to keep the
                oviduct exteriorized. A small opening is blunt dissected in the bursal membrane, allowing access
                to the ostium of the oviduct.
                Fifteen to twenty washed embryos are loaded into a transfer pipet in sterile media. The pipet is
                introduced into the ostium of the oviduct and the embryos gently expelled into the ampullary end of
                the oviduct.
                Following successful transfer, the mouse's reproductive organs are gently placed back into the
                body cavity. A single 5.0 vicryl suture is used to close the opening in the body wall if necessary.
                The edges of the skin at the incision are opposed and closed with a wound clip. The wound clip
                will be removed in <14 days.
                The mouse is placed back into her cage to recover. Buprenorphine (0.05-1.0mg/kg) is
                administered. If the animal is exhibiting sign of pain (hunching, stiffness) another dose will be
                administered 12 hours from the initial injection. No further analgesia is typically required. Gentle
                heat is applied by placing one end of the cage on a heating pad (aquamat) at low setting.
                Following recovery of the female in about 30-60 minutes, she is transferred to the mouse room.
 8.      Provisions for Post Surgical Care of the Animals:
             a. Who will be responsible for post operative care? Joe Andeerson; Peter Koch
             b. Post-operative analgesics be given:

Office Use Only, Protocol #
            (2) As needed, determined by:
             c. Where and how will animals be recovered from anesthesia? Room 0410C; animal will be
                 placed on a warming blanket (aquamat) to facilitate recovery.
             d. How frequently will animals be monitored during anesthesia recovery? Every 15 minutes
             e. What long term post-surgical care will be provided?
            (1) Wound monitoring and/or care
            (2) Provision of analgesics
            (3) Fluid supplementation
            (4) Special diet provisions
            (5) Antibiotics (specify type, dose and route)
        Please describe this care in detail.
 9.     Will any animal have more than one major survival surgical procedure?
            NO
            YES. If yes, then:
             a. Time interval between surgeries:
             b. Scientific necessity or rationale for performing more than one procedure in the same
                 animal instead of using more animals:
