| Abstract | Defining which key factors control commitment of an embryonic lineage among a myriad of candidates is a longstanding challenge in developmental biology and an essential prerequisite for developing stem cell-based therapies. Commitment implies that the induced cells not only express early lineage markers but further undergo an autonomous differentiation into the lineage. The embryonic neural crest generates a highly diverse array of derivatives, including melanocytes, neurons, glia, cartilage, mesenchyme, and bone. A complex gene regulatory network has recently classified genes involved in the many steps of neural crest induction, specification, migration, and differentiation. However, which factor or combination of factors is sufficient to trigger full commitment of this multipotent lineage remains unknown. Here, we show that, in contrast to other potential combinations of candidate factors, coactivating transcription factors Pax3 and Zic1 not only initiate neural crest specification from various early embryonic lineages in Xenopus and chicken embryos but also trigger full neural crest determination. These two factors are sufficient to drive migration and differentiation of several neural crest derivatives in minimal culture conditions in vitro or ectopic locations in vivo. After transplantation, the induced cells migrate to and integrate into normal neural crest craniofacial target territories, indicating an efficient spatial recognition in vivo. Thus, Pax3 and Zic1 cooperate and execute a transcriptional switch sufficient to activate full multipotent neural crest development and differentiation. |

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.
