Morphological analysis of Ipmk^tm1Yrk/Ipmk^tm1Yrk embryos

mortality/aging

embryonic lethality during organogenesis, complete penetrance ( J:99723 )

• homozygous embryos die between E10.5 and E12.5

embryo

incomplete embryo turning ( J:99723 )

• at E9.5 homozygous embryos are not turned

embryonic growth retardation ( J:99723 )

• at E8.5 embryos appear developmentally delayed

decreased embryo size ( J:99723 )

• at E8.5 homozygous embryos are smaller and shorter along the anterior to posterior axis

• at E9.5 homozygous embryos are about 20% smaller than their littermates

open neural tube ( J:99723 )

• at E9.5 the anterior neural tube is open

kinked neural tube ( J:99723 )

• at E9.5 the neural tube is kinked and folded
