From: Developmental expression of a functional TASK-1 2P domain K+ channel in embryonic chick heart
In situ hybridization of chicken TASK-1 expression in developing chick heart. A: in situ hybridization of S11 chick embryos. TASK-1 was ubiquitously expressed in S11 embryonic heart. B: In situ hybridization of TASK-1 in S18 chick embryonic heart. TASK-1 was expressed in the both the atrium and ventricle. However, expression appeared greatest in the trabeculae of the S18 heart. Whole mount In situ hybridization of TASK-1 in ED11 chick heart shown in C and D. C: a control in situ hybridization with sense RNA probe staining. No detectable purple staining was observed. D: TASK-1 was strongly expressed in the both right and left atria and lightly expressed in the ventricle in ED11 chick heart. Abbreviations are: heart (HT), myocardium (MC), neural tube (NT), trabeculae (Tb), atrial-ventricular cushion (AVC), right atrium (RA), left atria (LA), right ventricle (RV) and left ventricle (LV).
