Myelination by oligodendrocytes in the central nervous system (CNS) and Schwann
cells in the peripheral nervous system is essential for nervous system function
and health. Despite its importance, we have a relatively poor understanding of
the molecular and cellular mechanisms that regulate myelination in the living
animal, particularly in the CNS. This is partly due to the fact that myelination
commences around birth in mammals, by which time the CNS is complex and largely
inaccessible, and thus very difficult to image live in its intact form. As a
consequence, in recent years much effort has been invested in the use of smaller,
simpler, transparent model organisms to investigate mechanisms of myelination in
vivo. Although the majority of such studies have employed zebrafish, the Xenopus
tadpole also represents an important complementary system with advantages for
investigating myelin biology in vivo. Here we review how the natural features of
zebrafish embryos and larvae and Xenopus tadpoles make them ideal systems for
experimentally interrogating myelination by live imaging. We outline common
transgenic technologies used to generate zebrafish and Xenopus that express
fluorescent reporters, which can be used to image myelination. We also provide an
extensive overview of the imaging modalities most commonly employed to date to
image the nervous system in these transparent systems, and also emerging
technologies that we anticipate will become widely used in studies of zebrafish
and Xenopus myelination in the near future.
