Project description:Whole genome profiling of DNA methylation in Ciliary derived stem/progenitor cells and differentiated cells 6 samples total, 3 with CPE derived neurospheres and 3 with CPE derived differentiated progeny.
Project description:Whole genome profiling of histone methylation (H3K4me3, H3K27me3 and RNA Pol II) in Ciliary derived stem/progenitor cells and differentiated cells. In the present study we focus on the cellular differentiation that involves loss of pluripotency and gain of lineage and cell type-specific characteristics and we show developments from adult ciliary derived stem/progenitor cells to differentiated retinal neurons/glial cells of human cadaveric eyes in vitro. Ciliary pigment epithelial cells isolated from human cadaveric eye balls were cultured in the presence of mitogens like Epidermal Growth Factor (EGF) and Fibroblast Growth Factors (FGF) to generate neurospheres (Stem/progenitor population). The generated neurospheres were plated on laminin and poly-D-lysine-coated cover slips in the presence of the Brain derived neurotrophic factor (BDNF), Retinoic acid (RA) and 10% FBS for the differentiation (Retinal neuron/glial cells). Global Methylation patterns of histone H3K4me3, RNA Pol II and H3K27me3 were analysed in the present study. This work would provide an outline of epigenetic modifications in ciliary derived stem/progenitor cells and the progeny that underwent differentiation into retinal neurons/glial cells and present that specific histone methylations are involved in gene expression reprogramming during the process of differentiation.
Project description:Comparitive analysis of the retinal stem/progentior cells derived from the ciliary and iris pigment epithelial cells and the subsequent differentiated cells derived from the stem/progenitor cells. Gene expression profiling has shown great promise in analysing the reprogramming pattern of the cells under various culture conditions, in this context we analysed the various differential gene expression pattern of the neurospheres derived from the ciliary and iris pigment epithelial cells, and their differentiated cells. This provide an insite for the stem cell transplantation studies. We analysed 3 biological cultures derived from each catogory like the primary cells of both ciliary and iris pigment epithelial cells, the stem/progenitor cells (Neurospheres), neurosphere derived differentiated cells. No technical replicates were performed.

Project description:RNA-seq samples from 3 species across a differentiation from induced pluripotent stem cells to neural progenitor cells were generated to study gene expression evolution. Briefly, previously generated urinary stem cell derived iPSCs of 3 human (Homo sapiens) individuals (3 clones), 1 gorilla (Gorilla gorilla) individual and fibroblast derived cynomolgus macaque (Macaca fascicularis) iPSCs of 2 individuals (4 clones) (Geuder et al. 2021) were differentiated to neural progenitor cells via dual-SMAD inhibition as three-dimensional aggregation culture (Chambers et al. 2009; Ohnuki et al. 2014). Bulk RNA-seq libraries of iPSCs and NPCs were generated using prime-seq protocol (Janjic et al. 2022).

Project description:ATAC-seq samples from 2 species and 2 cell types were generated to study cis-regulatory element evolution. Briefly, previously generated urinary stem cell derived iPS-cells (Homo sapiens) of 2 human individuals and fibroblast derived cynomolgus macaque iPSCs (Macaca fascicularis) of 2 individuals (Geuder et al. 2021) were differentiated to neural progenitor cells via dual-SMAD inhibition as three-dimensional aggregation culture (Chambers et al. 2009; Ohnuki et al. 2014). The NPC lines were cultured in NPC proliferation medium and passaged 2 - 4 times until they were dissociated and subjected to ATAC-seq together with the respective iPSC clones. ATAC-seq libraries were generated using the Omni-ATAC protocol (Corces et al. 2017) with minor modifications.
Project description:This is a mathematical model describing the hematopoietic lineages with leukemia lineages, as controlled by end-product negative feedback inhibition. Variables include hematopoietic stem cells, progenitor cells, terminally differentiated HSCs, leukemia stem cells, and terminally differentiated leukemia stem cells.
