Fig 1. MS and GTO morphology in both neonatal and mature mouse soleus muscles are accurately reported using PV-Cre; R26-tdT and Adv-Cre; R26-tdT mouse models.

Examples of native tdTomato fluorescence in representative muscle spindles (A-C, G-I) and GTOs (D-F, J-L) from each of the mouse models utilized in this study. VGLUT1 expression was largely restricted to the proprioceptive receptor terminals, while tdTomato expression was observed in both proprioceptive receptor terminals and their respective axons. Scale bars represent 50 μm.
