| Abstract | Xenopus laevis is an ideal model system for investigating dynamic morphogenetic processes during embryogenesis, regeneration, and homeostasis. Our understanding of these events has been greatly facilitated by lineage labeling, that is, marking a cell or a group of cells and all their descendants using vital dyes, fluorescent molecules, or transplantation techniques. Unfortunately, these strategies are limited in their spatiotemporal resolution: They do not allow long-term dynamic in vivo imaging, are generally invasive, and labeling is restricted to cells on the surface. Genetically encoded fluorescent proteins (FPs), on the other hand, provide excellent alternative methods to traditional lineage labeling, enabling labeling with high spatiotemporal resolution and tracking of cellular and subcellular structures to study patterning events. Over the past decade, FPs have evolved to allow fine control of their spectral properties (in a defined region of interest) for greater labeling specificity. One example is EosFP, which is a protein cloned from the scleractinian coral Lobophyllia hemprichii that can be photoconverted from green to red fluorescence state with near-ultraviolet (UV) light irradiation. Here, we describe EosFP-photoconversion of Xenopus embryos to track cells during developmental and regenerative processes using a metal-halide- or xenon-arc-based fluorescent microscope system, which provides a simpler, less expensive alternative to photoconversion using laser microscopy. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
