| Abstract | While stem cells hold great promise as a means of treating otherwise incurable disease due to their characteristic ability to both self-renew and differentiate, they can also play a role in disease. Chronic myeloid leukemia (CML) arises in CD34+ hematopoietic stem, and is known resistant to the tyrosine kinase inhibitors imatinib and dasatinib. Understanding the mechanism which rescue particular fractions of cells from drug-induced death requires analysis at the single cell level. We demonstrate the ability to assay the response of normal and CML stem cells to dasatinib, a small molecule drug approved for treatment of imatinib resistant CML, within a novel microfluidic platform. Dynamic, on-chip three-color viability assays reveal that difference in responses of normal and CML cell to dasatinib are observed even in the early phases of exposure, during which normal cells exhibit a significantly elevated cell death rate as compared to both controls and CML cells. However, even in the CML fraction, dasatinib markedly reduces cell migratory behaviors in all but five percent of cells. This resistant fraction may hold the key to understanding CML persistence following chemotherapeutic assault. This work demonstrates the potential utility of single cell microfluidic platform in stem cell biology. |

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.
