Human bone-marrow-derived mesenchymal stem cells: control vs. cells undergoing chondrogenesis

ABSTRACT: Long non-coding RNAs profiling of human mesenchymal stem cells comparing undifferentiated HMSCs with differentiated HMSCs during chondrogenesis. The chondrogenic differentiation of HMSCs was induced by chondrogenic medium. The chondrogenic marker genes (Col2a1, Sox9 and ACAN) has been detected upregulating during this process by Q-PCR. The aim of this study is to determine key lncRNAs regulating the chondrogenic differentiation process.

Pioneering function of Yap and Taz in promoting osteogenesis of neural crest cells by preventing chondrogenesis

Project description:Neural crest cells (NCCs) are multipotent stem cells with a remarkable ability to differentiate into multiple cell lineages, including osteoblasts and chondrocytes. NCCs contribute to the majority of craniofacial skeleton, yet the molecular mechanisms regulating NCCs diversification into osteoblasts or chondrocytes remain poorly understood. We found that Yap and Taz function redundantly as key determinants of the osteogenesis versus chondrogenesis fate decision and differentiation in NCCs in vitro, ex vivo and in vivo, and Yap/Taz-deficiency in NCCs resulted in a switch from osteogenesis to chondrogenesis. Comprehensive analysis of unbiased datasets including CUT&RUN-seq and RNA-seq indicated that Yap/Taz directly regulate key genes that govern osteogenesis and chondrogenesis. During NCC-derived osteogenesis, Yap/Taz promote expression of osteogenic genes such as Runx2 and Sp7 but repress expression of chondrogenic genes such as Sox9 and Col2a1. Further, we found Yap/Taz directly interact with β-catenin in NCCs to coordinately promote osteoblast differentiation and repress chondrogenesis. Together our data indicate that Yap/Taz promote osteogenesis in NCCs by preventing chondrogenesis, partly through interactions with the Wnt-β-catenin pathway.

The transcription factors SOX9 and SOX5/SOX6 cooperate genome-wide through super-enhancers to drive chondrogenesis (ChIP-Seq)

Project description:SOX9 is a transcriptional activator required for chondrogenesis, and SOX5 and SOX6 are closely related DNA-binding proteins that critically enhance its function. We used RNA-seq to charatierize a rat chondrosarcoma (RCS) cells as a faithful model for proliferating/early prehypertrophic growth plate chondrocytes and ChIP-seq to gain novel insights into the full spectrum of the target genes and modes of action of this chondrogenic trio. ChIP-seq for SOX9, SOX6 and histone modifications were carried out using RCS cells

SOX9 is dispensable to initiate epigenetic remodeling and activation of marker genes at the onset of chondrogenesis (RNA-Seq)

Project description:Using whole-transcriptome and whole-epigenome sequencing approaches for wild-type and Sox9-deficient mouse embryo limb buds, we here identify genes specifically expressed and likely involved in precartilaginous condensation. We show that SOX9 directly upregulates these genes and well-known early-cartilage markers, and that its actions in chondrogenic cells have little impact on neighboring cell types. Intriguingly, we find that SOX9 helps remove epigenetic signatures of transcriptional repression and establish active-promoter and active-enhancer marks at precartilage- and cartilage-specific loci, but is not absolutely required to initiate these changes and activate transcription. Altogether, these findings widen our current knowledge of SOX9 targets in early chondrogenesis and call for new studies to identify the pioneer and transactivating factors that act upstream of or along with SOX9 to prompt chromatin remodeling and specific gene activation at the onset of chondrogenesis and other processes.

Effects of dynamic compressive loading on MSC chondrogenesis

Project description:Long-term dynamic compression enhanced the mechanical properties of MSC-seeded constructs only when loading was initiated after 21 days of chondrogenic differentiation. This study examined the molecular differences of chondrogenic MSCs compared to undifferentiated MSCs (TGF-beta vs no TGF-beta) and the effects of dynamic loading on MSC chondrogenesis (loading vs free-swelling). Free-swelling MSC-seeded constructs were cultured for 21 days in chemically defined media. Chondrogenesis was induced with TGF-beta3. Undifferentiated controls were maintained in parallel. After 21 days of chondrogenic differentiation, a subset of constructs were subjected to 21 days of dynamic compressive loading. On days 21 and 42, construct mechanical properties and biochemical content were assessed. Microarray analysis was carried out on day 3, day 21 and day 42 constructs. 6 arrays.

Effect of electromagnetic fields on the chondrogenic differentiation under microgravity conditions

Project description:A combination therapy of electromagnetic fields (EMF) and simulated microgravity (SMG) has not been examined in regenerative medicine of cartilage. In the present study, a bioreactor system using extremely low-frequency EMF and SMG was applied during the chondrogenic differentiation of human mesenchymal stem cells (hMSCs). It was hypothesized that a beneficial effect of EMF regarding chondrogenesis (COL2A) could be combined with an avoiding effect of SMG regarding hypertrophy (COLXA1) of cartilage. Pellet cultures of hMSCs formed cartilaginous tissue under the addition of growth factors (FGF; TGF-Î²3). Pure SMG reduced COLXA1 expression but also COL2A expression of hMSCs. Pure EMF showed no gene expression changes of hMSCs during chondrogenic differentiation. Combining EMF/SMG resulted in a re-increase of COL2A but did not reach control levels. The COL2A to COLXA1 ratio of combined EMF/SMG was not significantly different from control levels. The combination therapy of EMF/SMG did not significantly improve the chondrogenic potential of hMSCs. chondrogenic differentiation, electromagnetic stimulation-control, 1 timepoint with/without stimulation
