Figure Lengend Snippet: Maternal exercise alters growth plate morphometry and bone neovascularization. (A) Fluorescent staining for collagen type 10 alpha 1 chain (Col10a1) in the proximal hypertrophic zone (HZ) of embryonic day 17.5 (E17.5) humeri. Scale bar = 500 μm. (B) HZ length. (C) Fluorescent staining for alkaline phosphatase (ALP) activity in E17.5 humeri. Scale bar = 250 μm. (D) Primary ossification center (POC) ALP activity and (E) bone collar (BC) ALP activity. (F) Fluorescent staining for blood vessels (endomucin) in E17.5 humeri. Scale bar = 250 μm. (G) Medullary vessel area, (H) Medullary vessel density, (I) BC vessel area, (J) BC vessel density, (K) metaphyseal vessel area, and (L) metaphyseal vessel density. Fetuses from the same litter are marked by the same color datapoint. * p < 0.05 using a Student's t ‐test.
Article Snippet: Alkaline phosphatase (ALP) staining was conducted using the Vector blue Alkaline Phosphatase (ALP) substrate kit (SK‐5300, Vector Laboratories, Newark, CA, USA) according to the manufacturer's instructions.
