Histological analysis of wild type and Stat3tm1Aki/Stat3tm1Aki embryos

mortality/aging
• 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
• in culture, E3.5 mutant blastocysts exhibit a reduced ICM outgrowth relative to wild-type blastocysts
• homozygotes die at ~E7.0, the day at which gastrulation initiates
• at E6.0, homozygoys mutant embryos are smaller than wild-type embryos
• homozygotes show absence of mesoderm formation between E6.5 and E7.5

growth/size/body
• at E6.0, homozygoys mutant embryos are smaller than wild-type embryos

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

N normal phenotype
nervous system
• 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
• 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
• 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
