Project description:Tissue repair using cell transplantation holds popular appeal. This underlines the need to understand stem cells within the target organ. Our laboratory works on the human brain. Using neurosphere methods, we and others have only been able to passage stem/progenitors a very few times with little expansion of numbers. Now we describe an efficient method for the establishment and propagation of human brain stem cells from whatever tissue samples we have tried. We describe virtually unlimited expansion of an authentic stem cell phenotype. Pluripotency markers Sox2 and Oct4 are expressed without artificial induction. For the first time, multipotency of adult human brain-derived stem cells is demonstrated beyond tissue boundaries. We characterize these cells in detail in vitro including microarray and proteomic approaches. Whilst clarification of these cells' behavior is ongoing, results so far portend well for the future repair of tissues by transplantation of an adult patient's own-derived stem cells. Adult human brain stem cells from the subventricular zone were compared to those from hippocampus. Total RNA from three adult human brain biopsy sources: 3 subventricular-derived cell lines and 3 hippocampus-derived cell lines.

Brain stem cells and glioblastoma stem cells: adherent compared to sphere culture. Total RNA from three adult human brain biopsy sources and three brain tumour samples. Derived stem cell lines were grown as spheres and adherently. Comparison of cells under these culture conditions.

Grey matter and white matter: tissue, stem cells and differentiated cells compared. Total RNA from two brain biopsy sources (grey matter, white matter) from one adult human.

Project description:Mammalian spermatogonial stem cells (SSCs) spontaneously convert to multipotent adult spermatogonial-derived stem cells (MASCs) during in vitro expansion. Here, we examine the epigenetic signature of SSCs and MASCs, identifying bivalent histone H3-lysine4 and -lysine27 trimethylation at somatic gene promoters in SSCs and an ESC-like promoter chromatin state in MASCs.
