Using a range of tests we have studied alterations in behavior with advancing age in female C57BL/6 (of Jackson origin), the golden standard on which most genetically engineered mice are back-crossed. In parallel, growth and survival data were collected. In a protected environment the 90% and 75% cohort survival age was 20 and 25 months, respectively, and the 50% cohort survival was 32 months. In mice, body weight increases continuously until 15-20 months of age, while in advanced age whole… CONTINUE READING
