Preliminary observations on polar body extrusion and pronuclear formation in human oocytes using time-lapse video cinematography.
In this study, we have used time-lapse video cinematography to study fertilization in 50 human oocytes that had undergone intracytoplasmic sperm injection (ICSI). Time-lapse recording commenced shortly after ICSI and proceeded for 17-20 h. Oocytes were cultured in an environmental chamber which was maintained under standard culture conditions. Overall, 38 oocytes (76%) were fertilized normally,...
متن کاملA glass tissue culture chamber for use in time-lapse cinematography.
Numerous tissue culture chambers have been devised with the object of providing the optical requirements necessary for microscopic observation of the culture, and some of these incorporate a means of perfusion to facilitate changing medium, or to introduce various agents during the period of observation (Carrel, 1931 ; de Haan, 1931, 1938; Lindbergh, 1939; Parker, 1950). A few have been designe...
متن کاملLarge-scale time-lapse microscopy of Oct4 expression in human embryonic stem cell colonies
Identification and quantification of the characteristics of stem cell preparations is critical for understanding stem cell biology and for the development and manufacturing of stem cell based therapies. We have developed image analysis and visualization software that allows effective use of time-lapse microscopy to provide spatial and dynamic information from large numbers of human embryonic st...
متن کاملTime-lapse Stereo
Time-lapse stereo – using natural illumination changes in stereo reconstruction for large scale outdoor scene is yet an unexplored application of spacetime stereo framework. In this project, we collect several time-lapse stereo data sets for further research use and also evaluate the performance of time-lapse stereo by comparing the quality of its disparity images to the ones using classic ster...
متن کاملTime-lapse Monitoring with Multiply Scattered Waves
Previous formulations of coda wave interferometry make it possible to assess the average change of the medium, but they do not allow for the spatial localization of this change (Snieder et al., 2002; Snieder, 2002). We present an approach for localizing temporal changes in the medium using strongly scattered waves, and test it with numerical models for 2D scalar waves. Using an integral represe...
