＜Research＞
One cell, the egg, begins to divide after fertilization, and in the process, the cell-fate are decided and finally cells are differentiated. Even the seemingly simple early sea urchin embryo has a very complicated developmental process, and many mysteries are still hidden in its differentiation process. In our laboratory, we are studying which factors work at what timing and the fate of cells is determined using the early embryos of sea urchin. Currently, Yaguchi Lab is conducting research focusing on the following three points.
Axis specification
Similar to human being, sea urchin embryos have anterior-posterior, dorsal-abdominal, and left-right body axes. We are analyzing at the genetic level how each axis is determined and what kind of information is transmitted between each body axis.
Neurogenesis & Neural function
In the embryo of Hemicentrotus pulcherrimus, several serotonergic neurons are formed in the anterior neuroectoderm on the second day after fertilization. We are analyzing the molecular mechanism of serotonergic neuron differentiation and neuroectoderm formation, focusing on gene and protein expression patterns and functions.
We also analyze the neural function in the early development of sea urchins.
Sea urchin genetics
Echinoderms, including sea urchins, are recognized as non-model organisms because genetics cannot be applied due to its long breeding cycle. However, we found T. reevesii has short breeding cycle and succeeded to make inbred and genetically modified mutant strains. Using this species, we investigate the detailed function of sea urchin developmental genes.
