SUMMARY
Zebrafish have a characteristic horizontal-stripe pigment pattern made
by a specific distribution of three types of pigment cells: melanophores,
xanthophores, and iridophores. This pattern is a valuable model to investigate
how the spatial patterns form during animal development. Although recent
findings suggest that the interactions among the pigment cells play a
key role, the particular details of these interactions have not yet been
clarified. In this report, we performed transmission electron microscopic
study to show the distribution, conformation, and how the cells contact
with each other in the hypodermis. We found that the pigment cells form
complex but ordered, layered structures in both stripe and interstripe
regions. The order of the layered structures is kept strictly all through
the hypodermal regions. Our study will provide basic information to investigate
the mechanism of pigment pattern formation in zebrafish.
