The COE (Collier/Olf/EBF) family of transcription factors comprises a single member in Drosophila and four members in human and mice. We have examined by in situ hybridization the expression patterns of each ebf/coe gene during limb development in mouse and chicken embryos. Expression of mouse ebf1, 2 and 3 is detected in mesenchymal cells from stages E10.5-11, expression of ebf2 being restricted to the presumptive zeugopod. Cross sections of mouse and chicken limb buds at several stages reveal that ebfs are specifically expressed in the connective tissues surrounding chondrogenic condensations and forming tendons. They thus represent useful new markers for studying vertebrate limb development, particularly formation of ligaments.
