Figure 7


Fig. 7. TEM micrographs of a healthy stolon. (A) Epitheliomuscular cells (EMCs) in control stolons are found just inside of the perisarc and show the characteristic columnar shape. (B) The ectoderm is relatively wide (as indicated by the space between the perisarc and mesoglea) and nuclei can typically be seen suspended in a large vacuole. (C) The mitochondria of a healthy EMCs are usually about 0.5–0.75 µm. (D) Healthy EMCs near the stolon tip can be quite large as shown here. (E) The tip of a non-regressed stolon has a smooth and rounded appearance. P, perisarc; E, ectoderm; MG, mesoglea; N, nucleus; M, mitochondrion; V, vacuole. Scale bars, 1 µm.
