Expressioni

Developmental stagei

At stage 13 it is detected in the presomitic mesoderm, transiently observed before segmentation, and in the rostral part of the neural tube. Up-regulated in the neural tube, the retina and the otic vesicle from this stage on. At stage 17 a distinct stripe pattern was clear in the hindbrain and the spinal chord. Also found in the neuroepithelium of the midbrain and forebrain. The expression was down-regulated with the termination of neurogenesis at stage 36.
