Anatomical structures shown: hair cell polarity pattern in anterior macula
Stage: 5 dpf
Genetic (background) strain: none given
Animal state: fixed
Labeling: FITC-phalloidin (green); anti-acetylated tubulin (red)
Description: Orientation: dorsal - lateral to top, anterior to left. Polarity patterns of hair cells in a day 5 anterior macula. In plan view, the stereociliary bundle of each hair cell appears as a green crescent; the kinocilium (visible as a red dot in a few hair cells) is located in the concave side of the crescent. Arrows are drawn pointing from the stereocilia to the kinocilium. At this stage, nearly all hair cells radiate out from a site on the medial edge of the macula and point laterally; the orientation changes systematically from region to region, but the orientations of neighbouring hair cells in any given region are tightly correlated. Around the antero-lateral margin of the macula, there is a rim of hair cells pointing medially.
