Aspects of the present invention encompass the collection of multispectral images from a population of objects, and the analysis of the collected images to measure at least one characteristic of the population, using photometric and/or morphometric features identifiable in the collection of images. In an exemplary application, the objects are biological cells. In a particularly preferred, but not limiting implementation, the plurality of images for each individual object are collected simultaneously. In an empirical study, the characteristic being measured involves the synapse between conjugated cells. The conjugated cells may represent a subpopulation of the overall population of objects that were imaged. In a particularly preferred, yet not limiting embodiment, the present invention enables the quantization of the redistribution of cellular molecules due to the conjugation of different biological cells. Significantly, such quantization is not feasible with standard microscopy and flow cytometry.

The invention provides materials and methods for modulating adenoviral tropism for hepatocytes and other cell types such as splenocytes. It relates to the findings that hypervariable regions (HVRs) of the viral hexon protein interact with the Gla domain of the blood clotting factor FX as part of the infective process in vivo. The invention provides means to disrupt the interaction between hexon and FX, thus reducing infection of hepatocytes and splenocytes, as well as use of targeting agents comprising the Gla domain or a fragment thereof to direct adenoviral vectors to desired target cell or tissue types.

The present invention provides a transgenic animal expressing the reporter gene, luciferase, driven by a promoter (e.g. the E2F1 promoter) that acts as a sensor of cell cycle. The luciferase substrate, luciferin, emits light when metabolized, and the light is transmitted through mammalian tissues. Therefore, the transgenic animal model of the present invention allows for monitoring of areas of major cell cycle activity, a characteristic of cancer cells, under adequate visualization conditions. These transgenic animals are useful as in vivo models for testing preventative measures for cancer as well as for testing novel therapeutic modalities.
