mortality/aging
• nearly all mice die between E11.5 and E13.5
• however, rare adult survivors are observed
• nearly all mice die between E11.5 and E13.5 (J:169178)
• however, rare adult survivors are observed (J:169178)
• more than 99% of mice die between E11.5 and E13.5 from failed erythropoiesis (J:197237)

hematopoietic system
• mice die as a result from failed erythropoiesis
• however, primitive erythropoiesis and globin switching are normal
• 2-fold in the fetal liver
• in rare surviving mice at 1 to 4 months
• failed in most mice
• rare surviving mice exhibit a strong block to conventional (B-2) pro- and pre-B cell development compared with wild-type mice
• Rag2tm1Fwa Arid3atm1Pwt chimeras exhibit at 2- to 3-fold decrease in IgG1 class switching compared with control mice
• in rare surviving mice
• decreased 2-fold in the fetal liver
• in rare surviving mice at 1 to 4 months

cellular
• cultured spleen, bone marrow, lymph nodes or kidney cells exhibit overgrowth and spontaneously form aggregates resembling multicellular, partially differentiated embryoid bodies that express pluripotency-associated markers unlike wild-type cells
