Comparative Distribution and In Vitro Activities of the Urotensin II-Related Peptides URP1 and URP2 in Zebrafish: Evidence for Their Colocalization in Spinal Cerebrospinal Fluid-Contacting Neurons (original) (raw)
Fig 4
urp1 mRNA occurs in cells located along the ventral edge of the central canal of spinal cord in adult zebrafish.
Expression of urp1 revealed by ISH (BM purple, violet) on free-floating sections of adult spinal cord. urp1+ cells form a quasi-continuous line at the ventral edge of the central canal (A). urp1+ cells are in close contact to the lumen of the central canal (arrowhead) (B). A1 and A2, lateral sections with dorsal up; B, coronal section with dorsal up. urp1+ cells boxed in A1 are shown in A2 at higher magnification. M, melanocytes. Scale bars: 50 μm.
