    • Abstract


      A technique is described for obtaining a Sertoli cell-enriched and a germ cell-enriched fraction from immature rat testes. Sertoli cell-germ cell associations were obtained by incubating washed seminiferous tubule fragments with Collagenase and Pancreatin. They were then manually dissociated into a suspension comprising Sertoli cells as well as the various germ cell types characteristic for a given day of ontogeny. Fractionation into a Sertoli cell-enriched fraction and a germ cell-enriched fraction was effected by centrifugation following layering over a stepwise gradient of Ficoll-400. While the time-span compares favourably with other procedures reported in the literature, it is believed this is the first time a method is described that enables the simultaneous recovery of both the Sertoli cells and the germ cells.

      Forthcoming Special issue.

    • To trigger further research on plant mitochondria, the Journal of Biosciences is bringing out a special issue titled "Plant Mitochondria: Properties and Interactions with Other Organelles".

      Plant mitochondria are quite distinct and have unique features, such as a cyanide-insensitive alternate pathway. They also interact with chloroplasts to optimize photosynthetic carbon assimilation.

      Submissions are welcome until 30 July 2023. The contributions can be original articles, short communications, reviews, or mini-reviews on any topic related to plant mitochondria.

      Authors can submit their articles online at https://www.editorialmanager.com/jbsc/default2.aspx
