| Abstract | INTRODUCTIONTracing cell movements in a living embryo or embryo slice culture remains a challenging problem due to difficulties in cell accessibility and in accurate delivery of fluorescent labels into an individual cell or subgroup of cells. Here, we describe a photoactivation cell-labeling technique in avian embryos that allows for selective marking of individual cells or groups of cells at precise times and spatial locations normally not accessible using previous techniques. The current protocol is also less invasive than previously described methods. We provide details of fluorescent protein delivery into cells of interest utilizing microinjection and in ovo electroporation, as well as the optical parameters needed for photoactivation and imaging of both single- and dual-color photoactivatable fluorescent proteins (PAFPs). We present applications to label single cells and small subgroups of cells throughout the head and trunk of the developing vertebrate embryo, using the avian neural crest as our model cell population. |

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.
