Andeson, Ryuichi Tatsumi, Semaphorin 3A secreted from myogenic stem cells promotes slow-twitch muscle fiber generation, 2013 EMBO Workshop on“Semaphorin Function and Mechanism in Action”, 2013.10, Semaphorin 3A (Sema3A), a class 3 vertebrate-secreted semaphorin originally characterized as a potent neural chemorepellent, is now recognized to play crucial roles in angiogenesis, organogenesis, osteoclastogenesis and immune responses as a multi-functional modulator. Recently, we found that resident myogenic stem cells, satellite cells, up-regulate Sema3A expression and secretion exclusively at the early-myogenic differentiation phase in response to in vivo crush injury and hepatocyte growth factor treatment in the primary cultures (Tatsumi et al., 2009); however, its physiological significance in muscle regeneration is still unknown. Here we show that Sema3A impacts slow-type myosin heavy chain (slow-MyHC) expression in mouse satellite cell cultures. Sema3A-siRNA transfection significantly reduced expression of slow-MyHC as well as the muscle-specific transcription factor myogenin, and the down-stream mediators MEF2 as revealed by qPCR and western blotting analyses. Total MyHC expression level was unchanged, likely due to compensatory up-regulation of fast-MyHC during the 72-hr transfection period. Similar responses (except for fast-MyHC) were also observed in myogenin-knockdown cultures. In addition, reduced myogenin expression induced by immunoneutralization of the receptor neuropilin1 (Npn1) was rescued by co-addition of Sema3A protein. These results therefore indicate that Sema3A may activate a slow-MyHC expression-signaling axis consisting of Npn1, myogenin and MEF2. This model is supported by our comparative observations that satellite cells from soleus muscle (abundant in slow fibers) showed higher expression of Sema3A, myogenin and a co-receptor plexinA2 than those from EDL (Suzuki et al. 2013). Overall, the findings highlight a heretofore unexplored and active role for satellite cell-derived Sema3A as a key modulator of slow fiber generation during muscle regeneration, and advance our understanding of the multi-functional contributions of Sema3A..
34. Ryuichi Tatsumi, Judy E. Andeson, Ronald E. Allen, Muscle regeneration dynamics mediated by resident myogenic stem cells: a possible implication in moto-neuritogenesis and fiber-type regulation, Tucson Symposium 2013 on "The Biology of Muscle Growth and Repair", 2013.09, Skeletal muscle regeneration and work-induced hypertrophy are initiated by mechanical insult or other perturbation and one of the earliest events is triggering the activation (re-entry to cell cycle from G0) of quiescent resident myogenic stem cells, satellite cells. Recent studies of satellite cells in culture and in vivo addressed the possible dual-roles of hepatocyte growth factor (HGF) in the stretch-induced activation and the re-establishing quiescence. In the proposed scenario, the time-coordinated increase in extracellular HGF is a key modulator for the two contrary pathways having low and high thresholds to impact activation and the counterpart quiescence of satellite cells, respectively. Moreover, the role of HGF in muscle repair may not be restricted to myogenesis; we demonstrated that HGF up-regulates expression of secreted axon-guidance molecule semaphorin 3A (Sema3A) in satellite cells at early-differentiation phase in primary cultures and in vivo. The results encourage a possible implication of satellite cells in the spatiotemporal regulation of extracellular Sema3A concentrations, which potentially mediates restoration or remodeling of nerve-muscle connections in muscle regeneration in synchrony with recovery of muscle-fiber integrity and types (fast and slow). Very recently, we found in satellite cell cultures that the Sema3A ligand impacts slow-twitch fiber generation through a muscle-specific transcription factor myogenin-dependent pathway; Sema3A-siRNA transfection significantly reduced expression of slow-type myosin heavy chain (slow-MyHC) as well as myogenin and its co-mediator MEF2. Total MyHC protein expression level was likely unchanged, due to compensatory up-regulation of fast-MyHC and similar responses (except for fast-MyHC) were also observed in myogenin-knockdown cultures. Overall our results highlight the “programmed mechano-biology dynamics” that successful muscle regeneration, comprised of satellite cell-driving myogenesis, intramuscular moto-neuritogenesis and fiber-type regulation (survival), may be a programmed sequence of events that respond to a mechanical perturbation in a synchronous, HGF-dependent and time-coordinated manner..
