Life (Basel, Switzerland) 20220621 7

Integrin proteins are important receptors connecting the intracellular skeleton of satellite cells and the extracellular matrix (ECM), playing an important role in the process of skeletal muscle development. In this research, the function of ITGβ6 in regulating the differentiation of satellite cells was studied. Transcriptome and proteome analysis indicated that <i>Itgβ6</i> is a key node connecting ECM-related proteins to the cytoskeleton, and it is necessary for the integrity of the membrane s ...[more]

Fibronectin regulates Wnt7a signaling and satellite cell expansion

Project description:The influence of the extracellular matrix (ECM) within the stem cell niche remains poorly understood. We found that Syndecan-4 (Sdc4) and Frizzled-7 (Fzd7) form a coreceptor complex in satellite cells and that binding of the ECM glycoprotein Fibronectin (FN) to Sdc4 stimulates the ability of Wnt7a to induce the symmetric expansion of satellite stem cells. Newly activated satellite cells dynamically remodel their niche via transient high-level expression of FN. Knockdown of FN in prospectively isolated satellite cells severely impaired their ability to repopulate the satellite cell niche. Conversely, in vivo overexpression of FN with Wnt7a dramatically stimulated the expansion of satellite stem cells in regenerating muscle. Therefore, activating satellite cells remodel their niche through autologous expression of FN that provides feedback to stimulate Wnt7a signaling through the Fzd7/Sdc4 coreceptor complex. Thus, FN and Wnt7a together regulate the homeostatic levels of satellite stem cells and satellite myogenic cells during regenerative myogenesis. The data set contains one microarray of pooled quiescent skeletal muscle satellite cells

Comparing gene expression between PICs and satellite cells from 1 week old muscle

Project description:The satellite cell is considered the major tissue-resident stem cell underlying muscle regeneration, however, multiple non-satellite cell myogenic progenitors have been identified. PW1/Peg3 is expressed in satellite cells as well as a subset of interstitial cells with myogenic potential termed PICs (PW1+ Interstitial Cells). PICs differ from satellite cells by their anatomical location (satellite cells are sublaminal and PICs are interstitial), they do not express any myogenic marker and arise from a Pax3-independent lineage. Upon isolation from juvenile muscle (1 to 3 weeks old), PICs are capable to form both skeletal and smooth muscle suggesting they constitute a more plastic population compared to satellite cells. We used microarrays to gain insight into the relantionship between PICs and satellite cells. PICs and satellite cells were isolated from 1-week old mouse muscle and subsequent RNA extraction was performed.

Profiling of mouse muscle stem cells aging and activation upon skeletal muscle injury

Project description:Utilizing glycerol intramuscular injections in M. musculus provide a models of skeletal muscle damage followed by skeletal muscle regeneration. In particular, glycerol-induced muscle injury triggers accute activation of skeletal muscle stem cells, called satellite cells. However, aging dramatically impairs the regenerative capacity of satellite cells. We characterized genome-wide expression profiles of young and old satellite cells in the non-proliferative and activated state, freshly isolated to non-injured or damaged muscles, respectively. Our goal was to uncover new regulatory signaling specific to satellite cells entry into the activation and myogenic program that are affected with age. Satellite cells were isolated in either quiescent / non-proliferative or activated state from uninjured or 3 days after glycerol-induced injury of tibialis anterior, gastrocnemius and quadriceps, respectively. Young (2-4 months old) and old (20-24 months old) wildtype C57BL/6J male were used, with five to six biological replicates per group.

Transcriptional profiling of turkey muscle satellite cells transfected with MGP-siRNA during proliferation and differentiation

Project description:In this study, we directly compared turkey muscle satellite cell gene expression between satellite cells with the gene Matrix Gla Protein (MGP) knocked down by siRNA transfection and those transfected with a lipofectamine control using our 6K Turkey Skeletal Muscle Long Oligo (TSKMLO) microarray (GPL9788). The MGP gene was previously identified as differentially expressed by genetic line and during development of turkey skeletal muscle (Sporer et al., 2011). Gene expression changes were investigated in satellite cells after 72 h of proliferation and after 48 h of differentiation. We identified novel candidate genes and pathways as playing potentially crucial roles in the MGP-mediated effects on the normal processes of proliferation and differentiation in turkey satellite cells previously identified by Velleman et al. (submitted). This experiment was designed to investigate the role of MGP expression in turkey satellite cells during two crucial processes in muscle development: proliferation and differentiation. Satellite cells were isolated from 7-week-old turkeys from the RBC2 line. Cells were transfected with either MGP siRNA or a lipofectamine control; MGP expression was knocked down by over 50% with siRNA transfection (Velleman et al., submitted). Satellite cells were then induced to proliferate for 72h or differentiate for 48h; culture plates from each stage (n=4) were frozen until RNA extraction. Microarrays directly compared the MGP -knockdown to control from each of 4 culture plates and utilized a dye swap to equal 8 arrays for each of the cell developmental stages, proliferation and differentiation, and 16 arrays for the overall experiment investigating the role of MGP expression in satellite cell development and function. Hybridizations were performed in random order.

The VCAN gene was previously identified as differentially expressed by genetic line and during development of turkey skeletal muscle (Sporer et al., 2011).

Gene profiling of quiescent and activated skeletal muscle satellite cells by an in vivo approach

Project description:The satellite cell of skeletal muscle provides a paradigm for quiescent and activated tissue stem cell states. We have carried out transcriptome analyses by comparing satellite cells from adult skeletal muscles, where they are mainly quiescent, with cells from growing muscles, regenerating (mdx) muscles, or with cells in culture, where they are activated. Our study gives new insights into the satellite cell biology during activation and in respect with its niche. We used microarrays to study the global programme of gene expression underlying adult satellite cell quiescence compared to activation states and to identify distinct classes of up-regulated genes in these two different states Skeletal muscle satellite cells were isolated by flow cytrometry using the GFP fluorescence marker from Pax3GFP/+ mice skeletal muscle. The transcriptome of quiescent satellite cells from adult Pax3GFP/+ muscle was compared to the transcriptome of activated satellite cells obtained from three different samples: 1) regenerating Pax3GFP/+:mdx/mdx muscle (Ad.mdx) , 2) growing 1 week old Pax3GFP/+ muscle (1wk), and 3) adult Pax3GFP/+ cells after 3 days in culture (Ad.cult).

Geriatric muscle stem cells switch reversible quiescence into senescence (Set 4; Bmi1-deficient)

Project description:Regeneration of skeletal muscle depends on a population of adult stem cells (satellite cells) that remain quiescent throughout life. Satellite cell regenerative functions decline in geriatric satellite cells, compared to old cells are incapable of maintaining their normal quiescent state in muscle homeostatic conditions, and this irreversibly affects their intrinsic regenerative and self-renewal capacities. In geriatric mice, resting satellite cells lose reversible quiescence by switching to an irreversible pre-senescence state, caused by derepression of p16INK4a. Young Bmi1-deficient satellite cells shares similar features. We analyzed the global changes in gene expression occurring within muscle stem cells (satellite cells) in homeostatic conditions during physiological aging. Pure satellite cell populations from dissociated skeletal muscle from WT and Bmi1-deficient mice were isolated using a well-established flow cytometry protocol gating on integrin a7(+)/CD34(+) (positive selection) and Lin- (CD31, CD45, CD11b, Sca1) (negative selection).

Expression data of satellite cells through muscle injury time course

Project description:Satellite cells are resident skeletal muscle stem cells responsible for muscle maintenance and repair. In resting muscle, satellite cells are maintained in a quiescent state. Satellite cell activation induces the myogenic commitment factor, MyoD, and cell cycle entry to facilitate transition to a population of proliferating myoblasts that eventually exit the cycle and regenerate muscle tissue. The molecular mechanism involved in the transition of a quiescent satellite cell to a transit-amplifying myoblast is poorly understood. We used microarrays to detail the global program of gene expression of in vivo satellite cell activation through muscle injury and identified RNA post-transcriptional regulation as a key component of satellite cell activation. Wild type or Sdc4-/- satellite cells were FACS isolated from resting muscle or from muscle 12h and 48h following barium chloride-induced muscle injury. 5000 cell equivalents of RNA was labeled and hybridized to MOE430v2 GeneChips (Affymetrix) and scanned as per manufacturers protocol. Probeset intensities were GCRMA normalized for further analysis including UPGMA hierarchical clustering, analysis of variance (ANOVA), and fold change.
