Three-dimensional (3D) tracking of single secretory vesicles throughout live whole cells is crucial for understanding the intracellular trafficking of secretory vesicles. But one notable problem with 3D particle tracking is that the lateral and axial resolution is not equivalent for 3D live-cell images, which is attributed to the diffraction limit inherent to the microscope. How the performance of particle tracking is affected by diffraction-limited images is still unclear. Here we show, employing both centroid and Gaussian-fit tracking algorithm to monitor sub-pixel positions of single fluorescent particles, that the performance of three-dimensional single particle tracking is nonisotropic. The efficacy of the particle tracking in the axial direction is much lower than that in the lateral direction. Gaussian-fit tracking algorithm provides better performance in the axial direction at low signal-to-noise levels around or below 10. Using neuroendocrine cell line PC12, we illustrate the feasibility of Gaussian-fit algorithm to follow the mobility of single secretory vesicles in all three dimensions.","PeriodicalId":169717,"journal":{"name":"Proceedings. 2005 First International Conference on Neural Interface and Control, 2005.","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121341346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In present study, we use a polyclonal antibody against protein kinase C gamma subspecies (PKC /spl gamma/) as a specific marker of CST to reveal the precise localization of CST in rat spinal cord by immunohistochemistry. The strong PKC /spl gamma/ immunoreactivities in axons of CST were found in the pyramid and pyramidal decussation of medulla oblongata, and then from the cervical to lumbar spinal cord, PKC /spl gamma/ immunoreactivities were found to descend caudully through the white matter occupying the ventralmost portion of the posterior funiculus. At the conus medullaris, the positive reactivities of PKC /spl gamma/ appeared at the midline of the posterior funiculus. The area of positive reactivities of PKC /spl gamma/ decreased in size caudally in different spinal cord segments. These findings suggest that PKC /spl gamma/ immunohistochemical method can show the accurate position of corticospinal tract in rat spinal cord clearly, and provide the stereotactic anatomical bases for the microelectronic chip implantation in spinal cord.","PeriodicalId":169717,"journal":{"name":"Proceedings. 2005 First International Conference on Neural Interface and Control, 2005.","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125933363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
