Fig. 2. B4B2A5m mice have an impaired postnatal growth profile. (A,B) Sibling mice of matched sex, one control (left) and one transgenic (right) are shown together at two ages: 2 weeks (A, males) or 5.5 weeks (B, females). (C) Postnatal growth curves comparing the weight of control (n=4) and transgenic (n=7) male mice during the first 7 weeks of postnatal development. The growth rate of transgenic mice is significantly reduced during the second and third postnatal weeks. Growth resumes normally after 3 weeks but the mice remain smaller throughout adulthood.
