Growth retardation of Pa2g4Gt(OST186047)Lex/Pa2g4Gt(OST186047)Lex mice

reproductive system

growth/size/body
• at P19, body weight is reduced 30% compared to in wild-type mice
• regardless of reduced suckling competition, mice weigh 25% less than wild-type at P10 and P18
• however, by P60 mice have normal body weight

cellular
• proliferation of E12.5 mouse embryonic fibroblast is reduced compared to wild-type cells
• mouse embryonic fibroblasts achieve senescence at passage 3 unlike wild-type cells that do so at passage 5

limbs/digits/tail
• in one third of mice
