MicroRNA Contents in Matrix Vesicles Produced by Growth Plate Chondrocytes Are Cell Maturation Dependent

Project description:Chondrocytes at different maturation states in the growth plate produce matrix vesicles (MVs), membrane organelles found in the extracellular matrix, with a wide range of contents, such as matrix processing enzymes and receptors for hormones. We have shown that MVs harvested from growth zone (GC) chondrocyte cultures contain abundant small RNAs, including miRNAs. Here, we determined whether RNA also exists in MVs produced by less mature resting zone (RC) chondrocytes and, if so, whether it differs from the RNA in MVs produced by GC cells. Our results showed that RNA, small RNA specifically, was present in RC-MVs, and it was well-protected from RNase by the phospholipid membrane. A group of miRNAs was enriched in RC-MVs compared RC-cells, suggesting that miRNAs are selectively packaged into MVs. High throughput array and RNA sequencing showed that ~39% miRNAs were differentially expressed between RC-MVs and GC-MVs. Individual RT-qPCR also confirmed that miR-122-5p and miR-150-5p were expressed at significantly higher levels in RC-MVs compared to GC-MVs. This study showed that growth plate chondrocytes at different differentiation stages produce different MVs with different miRNA contents, further supporting extracellular vesicle miRNAs play a role as “matrisomes” that mediate the cell–cell communication in cartilage and bone development.

Transcription profiling of Bos taurus hypertrophic growth plate chondrocytes vs. reserve zone chondrocytes

Project description:Growth plate chondrocytes were isolated from the distal metacarpus of young dairy cattle (all under 10 mo of age), the chondrocytes were released from the extracellular matrix by digestion with Collagenase P for 4 hours, and the various zones of the growth plate were separated by density centrifugation. The least-dense Hypertrophic Zone (HZ) cells were compared to the most-dense Reserve Zone (RZ) cells. 6 pairs of HZ vs RZ were compared by microarray. Experiment Overall Design: Growth plate chondrocytes were isolated from the distal metacarpus of young dairy cattle (all under 10 mo of age), the chondrocytes were released from the extracellular matrix by digestion with Collagenase P for 4 hours, and the various zones of the growth plate were separated by density centrifugation. The least-dense Hypertrophic Zone (HZ) cells were compared to the most-dense Reserve Zone (RZ) cells. Six independent sample pairs of HZ vs RZ were compared by microarray.

Gene expression profile at single vell level of growth plate chondrocytes [scRNA-seq]

Project description:Gowth plate chondrocytes include heterogenous cell population and cellular diversity of these chondrocytes remains to be elucidated. We used single cell RNA sequencing to uncover the diverssity of growth plate chondrocytes and identify noel marker genes selectively expressed in pre-hypertrophic chondrocytes.

Selective enrichment of microRNAs in extracellular matrix vesicles produced by growth plate chondrocytes.

Project description:Matrix vesicles (MVs) are membrane organelles found in the extracellular matrix of calcifying cells, which contain matrix processing enzymes and regulate the extracellular environment via action of these enzymes. It is unknown whether MVs are also exosomic mediators of cell-cell communication via transfer of RNA material, and specifically, microRNA (miRNA). We investigated the presence of RNA in MVs isolated from cultures of costochondral growth zone chondrocytes. Our results showed that the average yield of MV RNA was 1.93±0.78ng RNA/10(4) cells, which was approximately 0.1% of the parent cell's total RNA. MV RNA was well-protected from RNase by the lipid membrane and was highly enriched in small RNA molecules compared to cells. Moreover, coding and non-coding small RNAs in MVs were in proportions that differed from parent cells. Enrichment of specific miRNAs was consistently observed in all three miRNA detection platforms that we used, suggesting that miRNAs are selectively packaged into MVs. MV-enriched miRNAs were related to different signaling pathways associated with bone formation. This study suggests a significant role for MVs as "matrisomes" in cell-cell communication in cartilage and bone development via transfer of specific miRNAs.

1α,25-Dihydroxyvitamin D3 Regulates Packaging of microRNAs within Extracellular Matrix Vesicles and Their Release in the Matrix

Project description:Growth plate chondrocytes are regulated by numerous factors and hormones as they mature during endochondral bone formation. Chondrocytes in the growth plate’s growth zone (GC cells) produce and export matrix vesicles (MVs) under the regulation of 1α,25-dihydroxyvitamin D3 [1α,25(OH)2D3]. 1α,25(OH)2D3 secreted by the cells acts on the MV membrane, releasing its contents. This study examined the regulatory role 1α,25(OH)2D3 has over the production and packaging of microRNA into MVs by GC cells and the ability to release microRNA from MVs once produced. We treated GC cells with 1α,25(OH)2D3 and then sequenced the microRNA in the cells and MVs. We also treated MVs with 1α,25(OH)2D3 and determined if the microRNA was released. To assess whether MVs can act directly with chondrocytes and if this is regulated by 1α,25(OH)2D3, we stained MVs with a membrane dye and treated GC cells with them. 1α,25(OH)2D3 regulated the production and packaging of microRNA into matrix vesicles. MVs did not release microRNA when treated with 1α,25(OH)2D3, indicating a heterogeneous MV population or a protective factor. Stained MVs were endocytosed by GC cells and this was increased with 1α,25(OH)2D3 treatment. This study adds new regulatory roles for 1α,25(OH)2D3 with respect to packaging and transport of MV microRNAs.
