Establishment of Clonal Colony-Forming Assay System for Pancreatic Stem/Progenitor Cells
Abstract:Pluripotent stem cells found in a number of organs are usually in small cell populations. However, under adaptive stimulation, they enter the stage of growth and differentiation to compensate for the loss of differentiated cells. To analyze stem cell potential precisely, the exclusion of other differentiated cells and a clonal assay system are strongly required. In this study, we established a colony-forming assay system for pancreatic stem/progenitor cells in vitro. In this culture condition, they received signals for growth and differentiation, and formed clonal colonies including pancreatic endocrine-lineage cells, such as α and β cells. By combining this culture system with flow cytometric cell sorting, pancreatic stem/progenitor cells will be enriched, and their potential can be analyzed precisely in single cell-based experiments.

- Cell Transplantation publishes original, peer-reviewed research and review articles on the subject of cell transplantation and its application to human diseases. To ensure high-quality contributions from all areas of transplantation, separate section editors and editorial boards have been established. Articles deal with a wide range of topics including physiological, medical, preclinical, tissue engineering, and device-oriented aspects of transplantation of nervous system, endocrine, growth factor-secreting, bone marrow, epithelial, endothelial, and genetically engineered cells, among others. Basic clinical studies and immunological research papers are also featured. To provide complete coverage of this revolutionary field, Cell Transplantation will report on relevant technological advances, and ethical and regulatory considerations of cell transplants. Cell Transplantation is now an Open Access journal starting with volume 18 in 2009, and therefore there will be an inexpensive publication charge, which is dependent on the number of pages, in addition to the charge for color figures. This will allow work to be disseminated to a wider audience and also entitle the corresponding author to a free PDF, as well as prepublication of an unedited version of the manuscript.
