(A) Representative FACS plots of cells isolated from TA muscles of Ovx mice without (n = 3) and with 17μ-estradiol treatment (Ovx+E2; n = 4).
(B) Total number of satellite cells.
(C) TA muscle mass.
(D) Total number of satellite cells relative to TA muscle mass.
(E) Maximal isometric torque (i.e., strength) expressed relative to pre-injury torque in Ovx mice without (Ovx+Placebo; n = 6) or with 17β-estradiol treatment (Ovx+E2; n = 8) following repeated injuries to TA muscle.
*p < 0.05 and **p < 0.005 by Student’s t tests (A–D) and Holm-Sidak post hoc (E).
