Histological analysis of wild type and Stat3^tm1Aki/Stat3^tm1Aki embryos

mortality/aging

embryonic lethality between implantation and somite formation, complete penetrance ( J:40106 )

• homozygotes develop into the egg cylinder stage until E6.0 but start undergoing rapid degeneration at E6.5

• all homozygotes are completely resorbed by E7.5

embryo

decreased inner cell mass proliferation ( J:40106 )

• in culture, E3.5 mutant blastocysts exhibit a reduced ICM outgrowth relative to wild-type blastocysts

failure to gastrulate ( J:40106 )

• homozygotes die at ~E7.0, the day at which gastrulation initiates

decreased embryo size ( J:40106 )

• at E6.0, homozygoys mutant embryos are smaller than wild-type embryos

absent mesoderm ( J:40106 )

• homozygotes show absence of mesoderm formation between E6.5 and E7.5

growth/size/body

decreased embryo size ( J:40106 )

• at E6.0, homozygoys mutant embryos are smaller than wild-type embryos

cellular

decreased inner cell mass proliferation ( J:40106 )

• in culture, E3.5 mutant blastocysts exhibit a reduced ICM outgrowth relative to wild-type blastocysts

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

nervous system

abnormal motor neuron morphology ( J:77229 )

• motor neurons require higher concentrations of CNTF than wild-type cells to survive in culture

• however, the number of facial and spinal neurons in mice is normal

abnormal neuron physiology ( J:77229 )

• motor neurons require higher concentrations of CNTF than wild-type cells to survive in culture

• however, the number of facial and spinal neurons in mice is normal

homeostasis/metabolism

increased susceptibility to injury ( J:77229 )

• after facial nerve transection, mice exhibit loss of facial motor neurons unlike in similarly treated wild-type mice

• however, treatment with BDNF or CNTF improves neuron survival after facial nerve transection
