Fig. 3From: Muscle spindle function in healthy and diseased musclePostnatal development of mouse muscle spindles. Muscle spindles from postnatal day 0: P0 (a), P8 (b), and P40 (c). Thy1-YFP mouse extensor digitorum longus were stained with anti-GFP antibodies. Only the central (equatorial) region is shown. Note the transformation of the “web-like” appearance of the sensory nerve terminal into the typical annulospiral ending during postnatal development. Scale bar in all panels: 50 μmBack to article page
