Although the rapid contraction of the axopodia at nearly a video rate (30 frames/s) is induced by mechanical stimuli, the mechanism underlying this phenomenon in R. contractilis has not yet been elucidated. In the present study, we described for the first time an adequate immunocytochemical fixation procedure for R. contractilis and the cellular distribution of α-tubulin before and after rapid axopodial contraction. We developed a flow-through chamber equipped with a micro-syringe pump that allowed the test solution to be injected at a flow rate below the threshold required to induce rapid axopodial contraction. Next, we used this injection method for evaluating the effects of different combinations of two fixatives (paraformaldehyde or glutaraldehyde) and two buffers (phosphate buffer or PHEM) on the morphological structure of the axopodia. A low concentration of glutaraldehyde in PHEM was identified as an adequate fixative for immunocytochemistry. The distribution of α-tubulin before and after rapid axopodial contraction was examined using immunocytochemistry and confocal laser scanning fluorescence microscopy. Positive signals were initially detected along the extended axopodia from the tips to the bases and were distributed in a non-uniform manner within the axopodia. Conversely, after the induction of a rapid axopodial contraction, these positive signals accumulated in the peripheral region of the cell. These results indicated that axopodial microtubules disassemble into fragments and/ or tubulin subunits during rapid axopodial contraction. Therefore, we hypothesize that the mechanism of extremely rapid axopodial contraction accompanied by cytoskeletal microtubule degradation in R. contractilis involves microtubule-severing at multiple sites. en-copyright= kn-copyright= en-aut-name=IkedaRisa en-aut-sei=Ikeda en-aut-mei=Risa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KurokawaMiki en-aut-sei=Kurokawa en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MuraiMomoka en-aut-sei=Murai en-aut-mei=Momoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SaitoNoboru en-aut-sei=Saito en-aut-mei=Noboru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AndoMotonori en-aut-sei=Ando en-aut-mei=Motonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Laboratory of Cell Physiology, Department of Science Education, Graduate School of Education, Okayama University kn-affil= affil-num=2 en-affil=Laboratory of Cell Physiology, Department of Science Education, Graduate School of Education, Okayama University kn-affil= affil-num=3 en-affil=Laboratory of Cell Physiology, Department of Science Education, Graduate School of Education, Okayama University kn-affil= affil-num=4 en-affil=Laboratory of Animal Physiology and Pharmacology, Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Laboratory of Cell Physiology, Department of Science Education, Graduate School of Education, Okayama University kn-affil= en-keyword=heliozoa kn-keyword=heliozoa en-keyword=immunocytochemistry kn-keyword=immunocytochemistry en-keyword=microtubule kn-keyword=microtubule en-keyword=glutaraldehyde kn-keyword=glutaraldehyde en-keyword=confocal microscopy kn-keyword=confocal microscopy END start-ver=1.4 cd-journal=joma no-vol=34 cd-vols= no-issue= article-no= start-page=21 end-page=27 dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=201804 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Cytoskeletal elements in an acoelomorph worm, Praesagittifera naikaiensis kn-title=無腸動物Praesagittifera naikaiensis における細胞骨格要素 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Acoel flatworms can move in a variety of ways such as muscular and ciliary movements via cytoskeletal elements and their neural regulations. However, those locomotive mechanisms have not yet been fully elucidated. In this study, we examined the distribution of cytoskeletal elements including filamentous actin (F-actin) and tubulin, and the neuroanatomical organization in an acoelomorph worm, Praesagittifera naikaiensis (P. naikaiensis). Video microscopy revealed the elongation/contraction and the bending/rotation processes, and the ciliary gliding movement of P. naikaiensis. Histochemical and morphological analysis demonstrated that F-actin networks of inner longitudinal and outer circular muscle fibers were positioned along the entire surface of the body, and that the average distance between the circular muscle fibers in the contracted organism was decreased in the anterior region compared with that in the elongated organism. Electron microscopy showed dense bodies on the muscle cells of P. naikaiensis, which indicates that those muscle cells have the appearance of vertebrate smooth muscle cells. Immunohistochemical analysis revealed that -tubulin-positive signals on the ciliary microtubules had close contact with the F-actin network, and that neurite bundles labelled with anti dSap47 antibody as a neuronal marker run along the anterior-posterior body axis. These results indicate that the well-organized cytoskeletal elements and their neural control systems are preserved in P. naikaiensis, and that their mechanisms involved in those regulation systems are similar to those vertebrate systems. Further studies are needed to clarify the physiological mechanisms underlying the muscular and ciliary movements in P. naikaiensis. en-copyright= kn-copyright= en-aut-name=IkedaRisa en-aut-sei=Ikeda en-aut-mei=Risa kn-aut-name=池田理佐 kn-aut-sei=池田 kn-aut-mei=理佐 aut-affil-num=1 ORCID= en-aut-name=FujiwaraChiho en-aut-sei=Fujiwara en-aut-mei=Chiho kn-aut-name=藤原稚穂 kn-aut-sei=藤原 kn-aut-mei=稚穂 aut-affil-num=2 ORCID= en-aut-name=HamadaMayuko en-aut-sei=Hamada en-aut-mei=Mayuko kn-aut-name=濱田麻友子 kn-aut-sei=濱田 kn-aut-mei=麻友子 aut-affil-num=3 ORCID= en-aut-name=SakamotoTatsuya en-aut-sei=Sakamoto en-aut-mei=Tatsuya kn-aut-name=坂本竜哉 kn-aut-sei=坂本 kn-aut-mei=竜哉 aut-affil-num=4 ORCID= en-aut-name=SaitoNoboru en-aut-sei=Saito en-aut-mei=Noboru kn-aut-name=齋藤昇 kn-aut-sei=齋藤 kn-aut-mei=昇 aut-affil-num=5 ORCID= en-aut-name=AndoMotonori en-aut-sei=Ando en-aut-mei=Motonori kn-aut-name=安藤元紀 kn-aut-sei=安藤 kn-aut-mei=元紀 aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=2 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 affil-num=3 en-affil=Ushimado Marine Institute, Faculty of Science, Okayama University kn-affil=岡山大学・理学部附属臨海実験所 affil-num=4 en-affil=Ushimado Marine Institute, Faculty of Science, Okayama University kn-affil=岡山大学・理学部附属臨海実験所 affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科 affil-num=6 en-affil=Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科 END start-ver=1.4 cd-journal=joma no-vol=33 cd-vols= no-issue= article-no= start-page=26 end-page=30 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=201704 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Structure and function of tegmentum vasculosum in avian cochlea kn-title=鳥類内耳tegmentum vasculosum の構造と機能 en-subtitle= kn-subtitle= en-abstract= kn-abstract= In spite of the importance of endocochlear DC potential (EP) and the K+-rich endolymph for the avian cochlea, the structure and function of the tegmentum vasculosum (TV) has not yet been fully elucidated, compared with those of the stria vascularis in the mammalian cochlea. In this study, we examined structural analysis of the epithelial cells, gene expressions of Na+-K+-ATPase (Atp1A1) and Kir4.1 (Kcnj10), and protein localizations of Na+-K+-ATPase and Kir4.1, in the TV. Tight junctional structures were observed between epithelial dark cells and light cells in the TV. Both Atp1a1 and Kcnj10 genes were detected in the TV. In addition, immunopositive signals for both Na+-K+-ATPase and Kir4.1 were recognized in the TV. These results indicate that Na+-K+-ATPase and Kir4.1 play roles in maintaining the EP and high K+ concentration of the endolymph. Further studies are needed to clarify the physiological functions of the TV. This is the first report which demonstrates that gene and protein expression data contribute to the avian inner ear homeostasis. en-copyright= kn-copyright= en-aut-name=IkedaRisa en-aut-sei=Ikeda en-aut-mei=Risa kn-aut-name=池田理佐 kn-aut-sei=池田 kn-aut-mei=理佐 aut-affil-num=1 ORCID= en-aut-name=OtonoTsuyoshi en-aut-sei=Otono en-aut-mei=Tsuyoshi kn-aut-name=乙野剛史 kn-aut-sei=乙野 kn-aut-mei=剛史 aut-affil-num=2 ORCID= en-aut-name=IkedaNaoya en-aut-sei=Ikeda en-aut-mei=Naoya kn-aut-name=池田直矢 kn-aut-sei=池田 kn-aut-mei=直矢 aut-affil-num=3 ORCID= en-aut-name=SaitoNoboru en-aut-sei=Saito en-aut-mei=Noboru kn-aut-name=齋藤昇 kn-aut-sei=齋藤 kn-aut-mei=昇 aut-affil-num=4 ORCID= en-aut-name=AndoMotonori en-aut-sei=Ando en-aut-mei=Motonori kn-aut-name=安藤元紀 kn-aut-sei=安藤 kn-aut-mei=元紀 aut-affil-num=5 ORCID= affil-num=1 en-affil=Laboratory of Cell Physiology, Department of Science Education, Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科・理科教育講座・細胞生理学研究室 affil-num=2 en-affil=Laboratory of Cell Physiology, Department of Science Education, Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科・理科教育講座・細胞生理学研究室 affil-num=3 en-affil=Laboratory of Cell Physiology, Department of Science Education, Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科・理科教育講座・細胞生理学研究室 affil-num=4 en-affil=Laboratory of Animal Physiology and Pharmacology, Department of Animal Science, Graduate School of Environmental and Life Science, Okayama University kn-affil=岡山大学大学院環境生命科学研究科・動物機能開発学講座・動物生理学研究室 affil-num=5 en-affil=Laboratory of Cell Physiology, Department of Science Education, Graduate School of Education, Okayama University kn-affil=岡山大学大学院教育学研究科・理科教育講座・細胞生理学研究室 END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue= article-no= start-page=55 end-page=58 dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=201504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Immunological identification of H+-coupled myo-inositol cotransporter in the lateral wall of the cochlea duct kn-title=蝸牛管側壁におけるミオイノシトール輸送体タンパク質の発現 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=YamajiMayumi en-aut-sei=Yamaji en-aut-mei=Mayumi kn-aut-name=山地真裕美 kn-aut-sei=山地 kn-aut-mei=真裕美 aut-affil-num=1 ORCID= en-aut-name=InoueRisa en-aut-sei=Inoue en-aut-mei=Risa kn-aut-name=井上理佐 kn-aut-sei=井上 kn-aut-mei=理佐 aut-affil-num=2 ORCID= en-aut-name=EdamatsuMidori en-aut-sei=Edamatsu en-aut-mei=Midori kn-aut-name=枝松緑 kn-aut-sei=枝松 kn-aut-mei=緑 aut-affil-num=3 ORCID= en-aut-name=AndoMotonori en-aut-sei=Ando en-aut-mei=Motonori kn-aut-name=安藤元紀 kn-aut-sei=安藤 kn-aut-mei=元紀 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院教育学研究科・理科教育講座・細胞生理学研究室 affil-num=2 en-affil= kn-affil=岡山大学大学院教育学研究科・理科教育講座・細胞生理学研究室 affil-num=3 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科・分子医化学分野 affil-num=4 en-affil= kn-affil=岡山大学大学院教育学研究科・理科教育講座・細胞生理学研究室 END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=1 article-no= start-page=97 end-page=102 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=20090310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The New Type of Lectures on the Development of Science Teaching Plans and Materials Tried in the Department ofEducation kn-title=理科教材･授業案開発を指向した新しい学部講義の実践 en-subtitle= kn-subtitle= en-abstract=This is a report of the new type of lectures on the development of teaching plans and teaching materials attempted in the science class for 3rd grade students in the Department of Education Okayama Universlty.
