Nestin, which was initially identified as a marker of neural stem cells, has been reported in regenerating pancreas as well as in early embryonic stem (ES) cell derivatives. However, little is known about its specific roles in stem cells as a functional regulator. We investigated the source of the action of nestin in ES and adult pancreatic ductal stem(More)
Human cytotoxic T-lymphocyte antigen 4-immunoglobulin (hCTLA4Ig) is an immunosuppressive therapeutic, and recently produced rice cell-derived hCTLA4Ig (hCTLA4IgP) reportedly exhibits in vitro immunosuppressive activities equivalent to those of Chinese hamster ovary cell-derived hCTLA4Ig (hCTLA4IgM). However, limitations of hCTLA4IgP include shortened in(More)
Tissue-specific stem/progenitor cells are found in various adult tissues and may have the capacity for lineage-specific differentiation, facilitating applications in autologous transplantation. Stage-specific embryonic antigen 4 (SSEA-4), an early embryonic glycolipid antigen, is expressed in cells derived from adult human pancreas exocrine tissue. Here, we(More)
Mesenchymal stem cells (MSCs) derived from bone marrow, adipose tissue, and most connective tissues have been recognized as promising sources for cell-based therapies. MSCs have also been detected in human pancreatic tissue, including endocrine and exocrine cells. These adult human pancreas-derived MSCs have generated a great deal of interest owing to their(More)
