Mouse Model for Osteoporosis (OP)

  • Product No.DSI534Mu01
  • Organism SpeciesMus musculus (Mouse) Same name, Different species.
  • Prototype SpeciesHuman
  • SourceInduced by ovariectomy
  • Model Animal StrainsC57BL/6 mice (SPF level), healthy, female not pregnant, week age:6W~8W, body weight 18g~20g
  • Modeling GroupingRandomly divided into groups: Control group, Model group, Positive drug group and Test drug group, 15 mice per group.
  • Modeling Period12 weeks
  • Modeling Method1. 3% sodium pentobarbital (40mg/kg)intraperitoneal injection of anesthesia, remove the abdominal hair, skin disinfection.
    2. Cut off the skin and the muscle layer in the middle of the abdomen on the sterile condition.
    3. Separate the uterus and remove the ovaries, and then suture the wound, after the mice awake, put them back to clean cage, observe the state and death of mice, and make records.
    4. 3 days after surgery, injecte 40 thousand units of penicillin to prevent infection for each mouse.
    5. For control group ,only remove about 1g fat around the ovary, while the ovaries are retained, and the other operation are the same.
    6. X-ray measurement of bone mineral density( BMD) on 12W, and intraperitoneal injection of anesthesia, get blood from eyeball, 4℃, 3000r/min,10min, separate the upper serum and stored at 80℃ for preservation of the refrigerator spare. Take the tibia of mice,and make pathological examination.

Model Evaluation of the Mouse Model for Osteoporosis (OP)

1. The changes of body weight, estradiol and bone mineral density in ovariectomized mice
In the ovariectomized group, the body weight increased rapidly, the activity ability decreased, the hair color is dull and gray, while the weight of the control group increased slowly, the hair color is bright, and the activity is normal. Estradiol levels and BMD of femur in the ovariectomized group are significantly decreased.

Pathological Results of the Mouse Model for Osteoporosis (OP)

From each mouse tibia specimens, placed in 10% neutral formalin fixed buffer solution (pH=7.2-7.4,4℃) fixed 24-48h. Then the 10%EDTA-2 Na buffer solution (pH = 7.4, 4℃) decalcification, every 5-7d to renew the decalcifying fluid; demineralized completely, dehydrated in graded ethanol and xylene transparent, longitudinal paraffin embedded, 5um sections, HE staining.
In the control group, the trabecular bone of the tibia is concentrated and interwoven into a network; the number of trabecular bone in the model group is significantly reduced, and the trabecular bone becomes thin.

Cytokines Level of the Mouse Model for Osteoporosis (OP)

Some studies have found that the lack of estrogen will lead to spontaneous reaction of the body. The expression of IL-6, IL-8, IL-1 and TNF-α in the serum of ovariectomized is increased, which could be detected by ELISA method.

Statistical Analysis of the Mouse Model for Osteoporosis (OP)

SPSS software is used for statistical analysis, measurement data to mean ± standard deviation (x ±ｓ), using t test and single factor analysis of variance for group comparison, P<0.05 indicates there was a significant difference, P<0.01 indicates there are very significant differences.
