hm1

• Allelic Composition: Myh9^{tm4(GFP/MYH10/MYH9)Rsad}/Myh9^{tm4(GFP/MYH10/MYH9)Rsad}
• Genetic Background: involves: 129S4/SvJae * C57BL/6

• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

mortality/aging

embryonic lethality during organogenesis, complete penetrance ( J:163702 )

• die between E9.5 and E10.5

embryo

embryo phenotype ( J:163702 )

N • unlike null mice, knock in embryos undergo gastrulation

abnormal vitelline vasculature morphology ( J:163702 )

• fewer visible vessels at E9.5 and E10.5

abnormal placenta morphology ( J:163702 )

• placentas are composed predominantly of clusters of cuboidal trophoblasts

abnormal spongiotrophoblast layer morphology ( J:163702 )

• the spongiotrophoblast layer is difficult to discern

abnormal placenta labyrinth morphology ( J:163702 )

• the labyrinth layer is difficult to discern

abnormal placental labyrinth vasculature morphology ( J:163702 )

• embryonic blood vessels fail to invade the labyrinth layer

abnormal placenta size ( J:163702 )

• thinner and more compact compared to controls

pale yolk sac ( J:163702 )

• at E9.5 and E10.5

cellular

abnormal actin cytoskeleton morphology ( J:163702 )

• in MEFs actin filaments are thin, disorganized and often fail to align with the direction of migration

abnormal cell adhesion ( J:163702 )

• fewer and smaller focal adhesions are detected in MEFs and the stress fibers in the focal adhesions are in disarray

abnormal cell migration ( J:163702 )

• a transwell assay indicates that directional cell migration is impaired in MEFs

• however, the speed at which MEFs close a wound is similar to that of wild-type cells

cardiovascular system

abnormal placental labyrinth vasculature morphology ( J:163702 )

• embryonic blood vessels fail to invade the labyrinth layer

abnormal vitelline vasculature morphology ( J:163702 )

• fewer visible vessels at E9.5 and E10.5
