Abstract:
Continuous observation of embryonic growth can improve understanding of the early developmental events and allow us to use parametric statistical analyses with time as a parameter. A cinematographic study such as that reported here utilizes time-lapse video recording. Previously published methods for time-lapse video recording have involved building an incubator around a microscope, a process that is both expensive and laborious. Here we present a simplified method for time-lapse video recording of early bovine embryo development. The embryos were cultured during a 24-hour period in a standard

Abstract:
The mitotic spindle is a complex and dynamic structure. Genetic analysis in budding yeast has identified two sets of kinesin-like motors, Cin8p and Kip1p, and Kar3p and Kip3p, that have overlapping functions in mitosis. We have studied the role of three of these motors by video microscopy of motor mutants whose microtubules and centromeres were marked with green fluorescent protein. Despite their functional overlap, each motor mutant has a specific defect in mitosis: cin8Δ mutants lack the rapid phase of anaphase B, kip1Δ mutants show defects in the slow phase of anaphase B, and kip3Δ mutants

Abstract:
Neurofilament is an important type of intercellular cargos transmitted in neural axons. Given fluorescence microscopy images, existing methods extract neurofilament movement patterns by manual tracking. In this paper, we describe two automated tracking methods for analyzing neurofilament movement based on two different techniques: constrained particle filtering and tracking-by-detection. First, we introduce the constrained particle filtering approach. In this approach, the orientation and position of a particle are constrained by the axon’s shape such that fewer particles are necessary for tra

The prevailing view is that the β2-integrins Mac-1 (αMβ2, CD11b/CD18) and LFA-1 (αLβ2, CD11a/CD18) serve similar biological functions, namely adhesion, in the leukocyte recruitment cascade. Using real-time and time-lapse intravital video-microscopy and confocal microscopy within inflamed microvessels, we systematically evaluated the function of Mac-1 and LFA-1 in the recruitment paradigm. The chemokine macrophage inflammatory protein-2 induced equivalent amounts of adhesion in wild-type and Mac-1−/− mice but very little adhesion in LFA-1−/− mice.

ABSTRACT Many viruses induce profound changes in cell metabolism and function. Here we show that vaccinia virus induces two distinct forms of cell movement. Virus-induced cell migration was demonstrated by an in vitro wound healing assay in which infected cells migrated independently into the wound area while uninfected cells remained relatively static. Time-lapse microscopy showed that the maximal rate of migration occurred between 9 and 12 h postinfection. Virus-induced cell migration was inhibited by preinactivation of viral particles with trioxsalen and UV light or by the addition of cyclo

Studies of Fc-mediated phagocytosis by mouse macrophages identified a contractile activity at the distal margins of forming phagosomes. Time-lapse video microscopic analysis of macrophages containing rhodamine-labeled actin and fluorescein dextran showed that actin was concentrated at the distal margins of closing phagosomes. Phagocytosis-related contractile activities were observed when one IgG-opsonized erythrocyte was engaged by two macrophages. Both cells extended pseudopodia until they met midway around the erythrocyte. It was then constricted and pulled into two phagosomes, which remaine

Abstract Time-lapse video microscopy has been used to study macrophage movement in the presence of SV40-transformed fibroblasts. In all, five different SV40-transformed cell lines (an uncloned line and four clones derived from it) were tested for their affects on the movement of LPS-activated macrophages (AM). Conditions for video microscope recording were designed to simulate, as best as possible, the conditions used in a 51Cr-release cytotoxicity assay. Our analysis shows that these targets had a range of effects on macrophage migration, from stimulation to complete inhibition of movement. T

Abstract:
Using long-term, time-lapse video-microscopy, we investigated how single progenitor cells isolated from the early embryonic cerebral cortex produce neurons and glia over time. Clones of 10 cells or less were produced by short symmetric or asymmetric division patterns, commonly terminating in a ‘pair progenitor’ for two morphologically identical neurons. Larger trees were composites of these short sub-lineages: more prolific neuroblasts underwent repeated asymmetric divisions, each producing a minor neuroblast that typically made (3/4)10 progeny, and a sister cell capable of generating more pro

Abstract Cell movement plays an important role during embryonic development (1). Much of what is presently known about cell movement is based on the behaviour of cultured cells. Despite refinements of culture conditions, however, extrapolation from events in vitro to behaviour in the embryo is difficult. Direct observation of living cells in vivo, when this can be done, is clearly preferable.
