The zinc finger transcription factor, Odd skipped-related 2 (OSR2) is a recognized marker of connective tissue in chick embryos. OSR2 gain- and loss-of-function experiments indicate a role in irregular connective tissue differentiation in chick limb undifferentiated cells. Re-investigation of OSR2 transcript location during chick development with in situ hybridization experiments showed that OSR2 was also expressed in differentiated muscle cells in limbs and head. OSR2 expression was also observed in differentiated myotubes in chick foetal myoblast cultures. This shows that in addition to being a marker of connective tissue, OSR2 is also expressed in muscle fibres during chick development.
