A Unique Cytoplasmic Marker for Extratesticular Sertoli Cells
Abstract:In the absence of a definitive cell marker for testis-derived Sertoli cells, their identification in cell culture or in Sertoli cell-facilitated cell transplantation protocols is difficult and limits the creditable evaluation of experimental results. However, the production by prepubertal Sertoli cells of Mullerian inhibiting substance (MIS) presents the possibility of specifically identifying extratesticular Sertoli cells as well as Sertoli cells in situ, by the immunodection of this unique glycoprotein. This study was designed to determine if isolated rat Sertoli cells could be identified by routine immunocytochemistry utilizing an antibody raised against MIS. Sertoli cells immunostained for MIS included Sertoli cells in situ and freshly isolated, cultured and cocultured Sertoli cells, and Sertoli cells structurally integrated with NT2 cells in simulated microgravity. Detection of MIS was also determined by Western blot analysis.

- 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.
