Urodelan amphibian larvae develop three pairs of branching external gills on both sides of the pharyngeal region, and this study focuses on motile cilia on the gill surface. High-speed camera was used to observe ciliary strokes on the surface of the

Biomolecules in living organisms, such as amino acids and double-stranded DNA, show left–right asymmetry. Even unicellular organisms, such as ciliates, have species-specific left- or right-handedness. Such molecular chiral asymmetry and cellular le

In most teleost fishes, the optic nerves decussate completely as they project to the mesencephalic region. Examination of the decussation pattern of 25 species from 11 different orders in Pisces revealed that each species shows a specific chiasmic ty

In Xenopus, multiple nodal-related genes are expressed in the organizer region. Among them, only Xenopus nodal related-1 (Xnr-1) is expressed unilaterally in the left lateral plate mesoderm (LPM) at late neurula-early tailbud stage. To elucidate the

In recent years, genes that show left–right (L-R) asymmetric expression patterns have been identified one after another in vertebrate gastrula–neurula embryos. However, we still have little information about when the irreversible L-R specificatio

In early chick blastodermal morphogenesis, the hypoblast layer is organized beneath the epiblast and induces an axial structure. However, the origin of hypoblast cells and the mechanism of hypoblast layer formation are poorly understood. We hypothesi

We developed a serum-free culture technique for chick epiblast explants in low density. In the condition free of unknown serum factors, we examined the invasiveness of chick epiblast cells by dissociating the cells into single cells and seeding them

To investigate the contribution of the epiblast cell behavior to the primitive streak formation, we examined the motility of a single epiblast cell from pre-streak stage embryo in vitro. On the substratum that was evenly coated with laminin gel, epib

Advancement of leading lamellae of a migratory cell inevitably causes a strain inside the cell body. We investigated the effect of the tension arisen inside a mesodermal cell on its behavior by pulling the cell body unidirectionally along the substra

Background It has long been known that cerebrospinal fluid (CSF), its composition and flow, play an important part in normal brain development, and ependymal cell ciliary beating as a possible driver of CSF flow has previously been studied in mammali
