Project description:We have established that BMP6 is an important endogenous regulator of human osteoblast differentiation. Our preliminary experiment showed that 8 hour BMP6 treatment induced early osteoblast markers in hMSC. In this study, we used microarrays to profile the global gene expression program in hMSC induced by BMP6 treatment and further identify the early osteogenic responses to BMP6 stimulation. Keywords: Stress response

In this study, we used microarrays to profile the global gene expression program in hMSC induced by BMP6 treatment and further identify the early osteogenic responses to BMP6 stimulation. Experiment Overall Design: The dataset contains a total of 4 gene chip measurements from duplicate experiments each with paired measurements of human MSC with or without 8 hours BMP6 treatment.

Project description:BMP6 mediated osteoblast differentiation plays a key role in skeletal development and bone disease. Unfortunately, the signaling pathways regulated by BMP6 are largely uncharacterized due to both a lack of data and the complexity of the response. To better characterize the signaling pathways responsive to BMP6, we conducted a time series microarray study to track BMP6 induced osteoblast differentiation and mineralization.

Unfortunately, the signaling pathways regulated by BMP6 are largely uncharacterized due to both a lack of data and the complexity of the response. To better characterize the signaling pathways responsive to BMP6, we conducted a time series microarray study to track BMP6 induced osteoblast differentiation and mineralization. Human MSC cells underwent osteogenic induction with BMP6 treatment for 0 hours, 8 hours, 24 hours, and 96 hours, which correspond to four phenotypic groups, i.e. control, preosteoblast (no mineralization), (sub-maximal) mineralization, and maximal mineralization at 14 days after the initiation of BMP treatment (18 days in total). Cells were harvested at 8 hours, 24 hours, 96 hours and 10 days for microarray profiling. Assays were run in duplicate for a total of 26 arrays. We only used 20 arrays in the reference paper.

Project description:Differentiation of human skeletal stem cells (hMSC) into osteoblasts is regulated by a few well described transcription factors. Our study used clustering and gene expression data to identify a novel transcription factor. ZNF25, which we showed is involved in osteoblast differentiation. We used microarrays to study gene expression of hMSC-TERT4 cells during osteoblast differentiation.

Our study used clustering and gene expression data to identify a novel transcription factor. ZNF25, which we showed is involved in osteoblast differentiation. We used microarrays to study gene expression of hMSC-TERT4 cells after siZNF25 knockdown. hMSC-TERT4 cells were sampled as undifferentiated hMSC and as differentiated osteoblasts.

Project description:Extensive changes in post-translational histone modifications accompany the rewiring of the transcriptional program during stem cell differentiation. However, the mechanisms controlling the changes in specific chromatin modifications and their function during differentiation remain only poorly understood. We show that histone H2B monoubiquitination (H2Bub1) significantly increases during differentiation of human mesenchymal stem cells (hMSCs), various lineage-committed precursor cells and in diverse organisms. Furthermore, the H2B ubiquitin ligase RNF40 is required for the induction of differentiation markers and transcriptional reprogramming of hMSC. This function is dependent upon CDK9 and the WAC adaptor protein, which are required for H2B monoubiquitination. Finally, we show that RNF40 is required for the resolution of the H3K4me3/H3K27me3 bivalent poised state on lineage-specific genes during the transition from an inactive to active chromatin conformation. Thus, these data indicate that H2Bub1 is required for maintaining multipotency of hMSC cells and plays a central role in controlling stem cell differentiation. This set contains 29 microarray samples and includes the following 5 conditions: undifferentiated hMSCs, 2 day osteoblast differentiation, 5 day osteoblast differentiation, 2 day adipocyte differentiation, and 5 day adipocyte differentiation. 3 siRNA control samples and 3 RNF40 knockdown samples for each condition (except two control siRNA samples for 2 days osteoblast differentiation).
