mortality/aging

prenatal lethality, complete penetrance ( J:77724 )

• mice begin to die at late E10.5

hematopoietic system

hematopoietic system phenotype ( J:77724 )

N	• despite disruptions in erythropoiesis and megakaryopoiesis, granulocytes and macrophages form normally

abnormal erythropoiesis ( J:77724 )

• erythropoeisis is arrested in maturation at a precursor stage

abnormal megakaryocyte progenitor cell morphology ( J:77724 )

• no megakaryocyte colonies can be generated from yolk sac cells unlike when wild-type cells are cultured

♀	phenotype observed in females

mortality/aging

neonatal lethality, complete penetrance ( J:77724 )

• remaining mice die shortly after birth

embryonic lethality during organogenesis, incomplete penetrance ( J:77724 )

• most mice die at E11.5

hematopoietic system

abnormal megakaryocyte differentiation ( J:77724 )

• late stage maturation of megakaryocytes generated in culture from yolk sac cells is disrupted with fewer platelet granules forming and disorganization in platelet demarcations unlike in wild-type cells

abnormal erythropoiesis ( J:77724 )

• yolk sac erythrocytes exhibit arrested maturation unlike in wild-type mice

anemia ( J:77724 )

• severe

abnormal megakaryocyte progenitor cell morphology ( J:77724 )

• slightly fewer megakaryocyte colonies can be generated from yolk sac cells compared to when wild-type cells are cultured

cellular

abnormal megakaryocyte differentiation ( J:77724 )
