Ylpm1^{tm1b(KOMP)Wtsi}/Ylpm1^{tm1b(KOMP)Wtsi} mice exhibit embryonic lethality, with embryos recovered at E7.5 but not at E9.5. Embryos are smaller and form a rudimentary egg cylinder but no primitive streak or hallmarks of gastrulation are seen at E7.5.

embryo

failure to gastrulate ( J:279207 )

• no hallmarks typical of gastrulating embryos are observed at E7.5

embryonic growth arrest ( J:279207 )

• embryos arrest prior to gastrulation

decreased embryo size ( J:279207 )

• embryos are much smaller than controls at E7.5

decreased egg cylinder size ( J:279207 )

• a rudimentary egg cylinder is observed at E7.5

absent head fold ( J:279207 )

• no head folds are present at E7.5

absent primitive node ( J:279207 )

• no embryonic node is present at E7.5

failure of primitive streak formation ( J:279207 )

• no morphological evidence of primitive streak formation is observed at E7.5

growth/size/body

decreased embryo size ( J:279207 )

• embryos are much smaller than controls at E7.5

mortality/aging
