Two new species of the family Nippobodidae (Acari, Oribatida), including a description of the leg-folding process

Nippobodes panemorfis sp. n. and Leobodes trypasis sp. n. are described by means of optical and Scanning Electron Microscopy (SEM) and compared to other congeners. The leg-folding process is described and illustrated. Nippobodes panemorfis sp. n. is characterised by interlocking, double hook-shaped, posterior prodorsal condyle and anterior zone humeral apophysis; posterior...


Glioblastomas (GBMs) are highly lethal brain tumors with florid vascularization. GBMs display striking cellular hierarchies containing self-renewing tumorigenic glioma stem cells (GSCs). As GSCs often reside in perivascular niches within a GBM tumor, we interrogated GSC potential to generate vascular pericytes in vivo. We demonstrated that GSCs give rise to pericytes to support...


INTRODUCTION: Recent evidence suggests that glioblastoma is driven by a subset of tumor initiating (TI) cells characterized by their capacity to form tumors in xenograft models and self-renew in vitro. These TI cells share many properties of neural stem/progenitor cells, including the expression of certain cell surface markers. With serial passage, many cells lose their capacity...
