Research methodologies include the following: gene expression studies, gain or loss of gene function studies, cryopreservation of zebrafish lines, importation of new lines, and characterization of phenotypes by time-lapse photography. Featured. Using in vivo time-lapse confocal microscopy, we show that zebrafish OPCs continuously extend and retract numerous filopodium-like processes as they migrate and settle into their final positions. The optical transparency of its embryos permits time lapse live imaging (Hall et al., 2009; Herrgen et al., 2009; Feierstein et al., 2015). In this study, using the zebrafish as the model system, we attempted to answer this classic question. /Im2 9 0 R /Im3 12 0 R >> >> In zebrafish, the lens placode appeared in the head ectoderm, similar to mammals. �AH�8V��?̬���ť٘ҭ*�l�W��h.t�&v���)���C�������1�vH���\�ݩ�s�09^�g�',�R$J�޻rn�7#�?���hىυ�,`��;���i������_���QV>�|`����^߬��/��Pqȉ.5dBeg)���(�j��}����8�BP�"�rX�O�������\����(��4�5��4 ��[;����e�5�9�f��7~�[b~�W��Oa� Uhr� Neuron 37 , 597 - 609 .

For Core Members Zebrafish Core in the NICHD Annual Report Time-lapse of a 2 day old zebrafish embryo with green erythrocytes and red blood vessels. Zebrafish embryos provide a unique opportunity to visualize complex biological processes, yet conventional imaging modalities are unable to access intricate biomolecular information without compromising the integrity of the embryos. 2 Imaging Station - Formative Evaluation Zebrafish Development Time-Lapse Video - Holding Time Joyce Ma August 2002 PURPOSE To determine how long visitors stay to watch the time-lapse video of Zebrafish development To determine if visitors stay to watch the entire video To determine if there is any difference in holding time between the annotated and the non- Zebrafish larvae were treated at 48 hpf with SKP2-C25 (1% DMSO). Time-lapse movie of zebrafish lens epithelial cells expressing GFP-histones and mCherry-zGem as they progress through the cell cycle. *To avoid redundant efforts, please check whether a suitable zebrafish line is already available through existing databases. Because of the rapid embryogenesis, external development, and transparency of zebrafish embryos, their developmental processes can be visualized in time-lapse studies in the context of the living organism.

Contrary to proposed models for vertebrate asymmetric divisions, no apico-basal cell divisions take place in the zebrafish retina during the generation of postmitotic neurons. Dr. Nils Lindstrom. Zebrafish Embryogenesis Brightfield imaging Time-lapse Morphogenetic movements Population statistics Quantification Temperature control This is a … In zebrafish, the lens placode appeared in the head ectoderm, similar to mammals. The transparency and rapid embryogenesis of zebrafish, together with fluorescent reporters, allow for the study of developmental processes with single-cell resolution using in vivo time-lapse imaging (Beis and Stainier, 2006). * Interoperability.

Bethesda, Maryland, USA. interval over a period of 13 h (Additional file 1: Movie S1). To determine whether the Erk biosensor could be used to monitor Erk activity in zebrafish embryos, 8SS embryos carrying the Erk biosensor were observed for 60 or 75 min at 5 min intervals at 28.5 °C. Field of Research: Developmental Neuroscience. Two-photon excitation microscopy was used to reconstruct cell divisions in living zebrafish embryonic retinas. Extended time-lapse imaging of vascular, neuronal and muscle development After optimizing the mounting method described above, time lapse confocal microscopy images were captured over a span of 55 h. We imaged live transgenic zebrafish expressing GFP or RFP in different tissues. At time = 0∶00 min, BDNF is applied in the bath and initiates a Ca 2+ signal in the growth cone by 5 min. Summary. The zebrafish is a favorite model organism to study tissue morphogenesis during development at a subcellular level.
