start stage end stage olfactory support cell crypt neuron olfactory support cell zebrafish_anatomy ZFA:0005770 Ceri 2013-11-05T11:05:25Z Specialized olfactory support cell that surrounds crypt olfactory sensory neurons. There are one or two support cells for each crypt neuron. The cytoplasm of crypt neuron olfactory support cells is less electron dense then other support cells. They also bear numerous microvilli at their apical rim. When two supporting cells are present, they interdigitate with each other Mitochondria in crypt supporting cells are larger than those in the common supporting cells. unknown adult
