Abstract

Tbx2 belongs to the T‐box transcription factor gene family and is expressed in a variety of tissues and structures throughout development, although not all expression domains have been thoroughly described. Two areas of segmented expression along the rostral‐caudal axis of E10.5–11.5 embryos were identified as inter‐somitic vessels and dorsal root ganglia. In addition, Tbx2 expression is observed during somitogenesis beginning at E9.5, both in the posterior half of prospective somites and in a progressively restricted pattern in recently formed somites.
