From: Effect of prostaglandin E2 injection on the structural properties of the rat patellar tendon
Representative transmission electron microscopy images of the cross-section of the rat patellar tendon. Image (A) is for a control rat and image (B) is for a PGE2-8 wk treated rat. Scale bar of the electron micrographs = 500 nm. The mean fibril diameter (Mean ± SD) of the rat patellar tendons (n = 5) was found to be similar (P > 0.05) in the control (154 ± 45) and PGE2-8 wks (167 ± 50) groups.
