Abstract
Quiescent satellite cells, known as adult muscle stem cells, possess a remarkable ability to regenerate skeletal muscle following injury throughout life. Although they mainly originate from multipotent stem/progenitor cells of the somite, the mechanism underlying the establishment of quiescent satellite cell populations is unknown. Here, we show that sex hormones induce Mind bomb 1 (Mib1) expression in myofibres at puberty, which activates Notch signalling in cycling juvenile satellite cells and causes them to be converted into adult quiescent satellite cells. Myofibres lacking Mib1 fail to send Notch signals to juvenile satellite cells, leading to impaired cell cycle exit and depletion. Our findings reveal that the hypothalamic–pituitary–gonadal axis drives Mib1 expression in the myofibre niche. Moreover, the same axis regulates the re-establishment of quiescent satellite cell populations following injury. Our data show that sex hormones establish adult quiescent satellite cell populations by regulating the myofibre niche at puberty and re-establish them during regeneration.

In the version of this Article originally published, in the key in Fig. 1b, the red and black data points were incorrectly labelled; the red data points should have been labelled ‘DHT’ and the black data points as 'Veh'. Furthermore, in the key in Fig. 2c, the red and black data points were also incorrectly labelled; the red data points should have been labelled 'N1ΔSC', and the black data points as 'N1WT'. These errors have been corrected in the online versions of the Article.

(g,h) The expression of Ar and Esr2 in MFs (g) and Notch target genes in SCs (h) from 4-week-old Veh and Antide-treated mice. n = 3 animals for each group; data are mean ± s.d.; Two-sample t-test; ∗P < 0.05. (i) IHC staining of Pax7 and Ki67 in TA muscles from 4-week-old Veh and Antide-treated mice. Quantification data is presented in Fig. 6b left subfigure. Arrows and arrowheads indicate Pax7+Ki67+ and Pax7+Ki67− cells, respectively; scale bar, 50 μm.
Supplementary Figure 8 Genetically disturbed hypothalamic and gonadal axis impairs the establishment of SC population.
(a,c) Gross morphology of seminal vesicles, testes and LA muscles (a; scale bar, 0.2 cm), muscle mass (b; n = 3 animals for each group; data are mean ± s.d.; Two-sample t-test; *P < 0.05) and myonuclei number of EDL muscles (c; n = 3 animals for each group; data are mean ± s.d.; Poisson’s general linear model regression; N.S. not significant) in 8-week-old Gnrh1+/+ and Gnrh1hpg/hpg mice. Muscle mass and myonuclei numbers were comparable in Gnrh1+/+ and Gnrh1hpg/hpg mice. (d,e) The expression of Ar and Esr2 in MFs (d) and Notch target genes in SCs (e). n = 3 animals for each group; data are mean ± s.d.; two-sample t-test; ∗P < 0.05; ∗∗P < 0.01. (f) IHC staining (f) for Pax7 and Laminin in TA muscles. MFs, SCs, and TA muscles were isolated from 8-week-old Gnrh1+/+ and Gnrh1hpg/hpg mice. Scale bar, 50 μm. (g) Flow cytometric analysis of mononuclear cells from 8-week-old control (sum data of Sham, Veh, and Gnrh1+/+), Orx, Antide-treated, and Gnrh1hpg/hpg hindlimb muscles. n = 3 animals for each group; data are mean ± s.d.; Bootstrap t-test; ∗P < 0.05. (h) IHC staining of Pax7 in Vcam-1+Sca-1− cells sorted from mononuclear cells of Gnrh1+/+and Gnrh1hpg/hpg mice. Scale bar, 50 μm. (i) The representative chromatograms of E2 measurements by LC-MS/MS. n = 3 animals for each group; Data are mean ± s.d.
