ビデオ・アーカイブ

本領域の事業の一環として,細胞運動のビデオのオンラインライブラリーを作成します.細菌,真核生物,アーキア(古細菌),ウイルス,タンパク質, 合成ポリマー,など様々なものの動きを公開します.それぞれのビデオは,私たちが生物学的に掲載価値があるかどうかを判断,分類し,和文と英文で解説します.

ライブラリー作成のため,皆さまに,(1) 研究者によるご自身の研究対象の投稿,(2) スーパーサイエンスハイスクールや生物部の活動などで顕微鏡をのぞいていて見つけた微生物の投稿,などをお願いします.また,(3) 論文のビデオなどで当ライブラリーにリンクしてほしいもの,(4) 周囲に眠っている古いビデオ教材などでアーカイブ化の価値がありそうなもの,については領域事務局までご一報ください.

ライブラリーのアクセスランキングを下記のリンク先で公開しています。直近の3か月のアクセス数の多いビデオ10本を見ることができます。

また、ビデオ・アーカイブをより手軽に楽しんで頂くために、閲覧用スマートフォンアプリを開発いたしました。
以下からダウンロードできますので、是非ご覧下さい。

真核生物
Sperm motility in seminal receptacle of control female

Department of Biology, Center for Genomics and Systems Biology, New York University, New York, New York, United States of America Professor Mark L. Siegal

Control female at 5 d post-mating. Note motility of sperm and lack of clumping.

Loss of sperm motility in seminal receptacle of Spermathecal Secretory Cells (SSC) ablated female

Department of Biology, Center for Genomics and Systems Biology, New York University, New York, New York, United States of America Professor Mark L. Siegal

Experimental female at 5 d post-mating. Note reduced sperm motility and clumping of sperm heads.

Live birth of fully developed embryo by an ovoviviparous female

Department of Biology, Center for Genomics and Systems Biology, New York University, New York, New York, United States of America Professor Mark L. Siegal

Movements of the larval mouth hooks and trachea are visible through the eggshell, shortly after release from a female with Spermathecal Secretory Cells (SSC) ablated prior to mating.

Actin Filament Interacting with Listeria monocytogenes

種名:Listeria monocytogenes
Center for Cell Dynamics, University of Washington, Friday Harbor, Washington, United States of America Professor Jonathan B. Alberts

Listeria monocytogenes moves by actin-based motility. A close-up look at the interaction of a single polymerizing filament with the bacterium based on in silico reconstitution. This filament has an artificially durable link with an ActA protein on the bacterium's surface; these links are typically very transient. The tip-clearance (drawn with a cyan line), the polymerization probability, the capping probability, and the Arp2/3 binding probability are reported at each simulation time-step

Motion initiation and persistence of actin-based motility

種名:Listeria monocytogenes
Center for Cell Dynamics, University of Washington, Friday Harbor, Washington, United States of America Professor Jonathan B. Alberts

An animation rendered from the output of one simulation of Listeria monocytogenes motility. Microscale hops, as opposed to the nanoscale steps we investigate are apparent at this scale view. The bacterium induces an actin tail of variable density and demonstrates persistent motion.

Bundling pattern of bacterial microtubules, BtubA/B-candidate structures from Prosthecobacter vanneervenii

California Institute of Technology, Pasadena, California, United States of America, and Howard Hughes Medical Institute, Division of Biology, Pasadena, California, United Professor Grant J. Jensen
States of America 

Bacterial microtubules were observed alone or in bundles of up to four. The movie shows a bundle of four parallel bacterial microtubules. Cross-sectional views (2-D tomographic slices) are followed by a 3-D segmentation (the four different bacterial microtubules are shown in four different colors).

Mitotic Spindle Assembly around RCC1-Coated Beads in Xenopus Egg Extracts (No. 1)

Department of Molecular & Cell Biology, University of California–Berkeley, Berkeley, California, United States of America Professor Rebecca Heald

Two side-by-side fluorescence time-lapse movies of egg extract spindle assembly reactions containing rhodamine labeled tubulin are shown over the time interval of 38 min. On the left is a spindle formed around an RCC1-coated bead (green), and on the right a spindle assembled around a chromatin-coated bead (blue). Note that the RCC1 bead spindle is smaller, and that the bead oscillates from pole-to-pole.
