Expressioni

Tissue specificityi

Expressed in brain and retina.

Developmental stagei

Expression is confined to regions of the developing nervous system and pancreas. At E13 expressed at lower levels in the trigeminal ganglion, the ganglionic eminence, the ventral neural tube, and dorsal root ganglia. Expressed at moderate levels in the tectum of the embryonic midbrain. Most prominent expression is in the diencephalon, where it flanks either side of the roof of the third ventricle, dorsal/caudal to the dorsal thalamus. Detected in the pancreas during the time when most of the pancreatic endocrine cell types are beginning to differentiate and endocrine precursor cells remain loosely associated with the duct epithelium until they begin to form aggregates late in development.1 Publication
