| Abstract | Previously, we reported the presence of certain nonparenchymal epithelial cells (NPECs) in adult porcine livers that demonstrate differentiation patterns including an emergence of duct-like structures (DLSs) in the colonies. In the present study, we examined the effect of supplements to the NAIR-1 medium (Dulbecco modified Eagle medium [DMEM]-F12 containing 5% fetal bovine serum [FBS] and 11 supplements) used in these cultures on formation of DLSs-emerged colonies (type I colonies). No type I colonies were observed in the cultures of the nonparenchymal cell fraction when Roswell Park Memorial Institute-1640 medium or DMEM-F12 (1∶1) supplemented with 5% FBS was used as the culture medium. NAIR-1 medium without each component did not produce any significant results. No type I colonies were formed when epidermal growth factor, and hydrocortisone and insulin mixture (A) or nicotinamide and l-ascorbic acid phosphate magnesium salt (Asc2P) mixture (B) was added to the DMEM-F12 medium supplemented with 5% FBS. However, when a combination of A and B was added, colonies were formed at a significant level. Together, the number of type I colonies was increased in the combination of A and B containing a higher concentration of Asc2P. We conclude that NPECs need a mixture of Asc2P and other components as supplements for type I colony formation. |

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.
