The plumage on the dorsal trunk of normal quail embryos exhibits longitudinal black and brown stripes of pigments produced by melanocytes. However, this pigmentation pattern disappeared in Bh (black at hatch) heterozygous and Homozygous embryos be...
The spatio-temporal expression of three crystallin genes (alpha A, beta B1 and gamma) in lenses of Xenopus laevis was studied by in situ hybridization to compare the process of lens formation in embryonic development with that of lens regeneration...

Avian embryos can be cultured in vitro from the single-cell stage to hatching. If the capsular thick albumen is removed, the germinal disc at this stage is recognized more clearly with the aid of an image-processor system. We have succeeded in cul...
During early stages in avian embryogenesis primordial germ cells (PGCs) show a unique migration pathway toward the gonadal anlage through the circulation. In the present study, liposomes consisting of plasmid DNA (pMiwZ; containing lacZ as a repor...
Amputation of the larval tail of Xenopus injures the notochord, spinal cord, muscle masses, mesenchyme, and epidermis, induces the growth and differentiation of cells in those tissues, and results in tail regeneration. A dorsal incision in the lar...

We examined several candidate posterior/mesodermal inducing molecules using permanent blastula-type embryos (PBEs) as an assay system. Candidate molecules were injected individually or in combination with the organizer factor chordin mRNA. Injecti...

Tail regeneration in urodeles is dependent on the spinal cord (SC), but it is believed that anuran larvae regenerate normal tails without the SC. To evaluate the precise role of the SC in anuran tail regeneration, we developed a simple operation m...

The tail of the Xenopus tadpole contains major axial structures, including a spinal cord, notochord and myotomes, and regenerates within 2 weeks following amputation. The tail regeneration in Xenopus can provide insights into the molecular basis o...

We succeeded in visualization of the primordial germ cells (PGCs) in a living Xenopus embryo. The mRNA of the reporter Venus protein, fused to the 3' untranslated region (UTR) of DEADSouth, which is a component of the germ plasm in Xenopus eggs, w...
