Outline of Research at the Start

体の隅々にまで存在する血管網は、酸素や栄養などを運ぶ重要な運搬流路である。一方で初期胚に出現する原始血管網はそれ以外の役割も担うと考えられているが、その実態はよくわかっていない。私達は、初期胚における原始血管網の血流を局所的に操作すると、そこから遠く離れた場所の血管パターンにまで変化が及ぶことを見出し、またこのような連鎖的な血管リモデリングがその後の器官形成にも関わる可能性がみえてきた。そこで本研究では「初期胚の血管ダイナミクスが、その後の器官形成を支える」という着想に基づいて、ミクロからマクロまでを繋ぐ解析法により、血流メカノ刺激の連鎖に連動する器官形成のダイナミクスの基盤を提唱する。

Outline of Final Research Achievements

Vascular system plays a pivotal role in conveying oxygen and nutrients, and its formation and patterning during early developing follow some rules. In this study, we asked how the blood flow regulates the vascular patterning. In early chicken embryos, geometric patterns of vitelline arteries (VAs) that laterally extend from the dorsal aorta at the level of 20th somites facilitate analyses at high resolution. We found that the onset of hear beat-driven blood flow is intimately correlated with the he VA patterning. An occlusion of blood flow markedly affected the VA patterning, suggesting that the mechanical stimulation by blood flow plays an important role. We further found that Rho activity needs to be properly controlled for the blood flow-regulated VA patterning. The findings obtained in this study are expected to help understanding how blood flow regulates tumor and cancer cells.

Academic Significance and Societal Importance of the Research Achievements

血管バイオロジーの分野において、血管リモデリング機構の理解は非常に遅れている。その理由として、血流刺激を必要としている血管リモデリングをin vitro系で再構築するのが困難であることなどが挙げられる。本研究では、2次平面上で血管形成が進むニワトリ初期胚の利点をいかして、血管リモデリングにおける血流刺激の影響を高解像度で解析できた点が意義深い。血流のタイミングが動脈の位置パターニングを規定するなど、他の解析系では見出せなかった発見を打ち出すことができた。血管系疾患やガン生物学とその治療法開発にむけて、新たな道の開拓につながることが期待される。
