From: A transmission electron microscopy investigation suggests that telocytes, skeletal muscles, myoblasts, and stem cells in common carp (Cyprinus carpio) respond to salinity challenges

Fig. 5

Skeletal muscle fibers undergo hypertrophy in response to salinity. Colored ultra-thin sections in gill arches control (A) and treated samples with 6 ppt (A-C),10 ppt (D, E) level of salinity. A, B: in control samples, telopode (T) adjacent to skeletal muscle fiber which received telocytes secretory vesicles. Note the secretory vesicles (arrows) located in intracellular compartments (C) in the muscle cell. Note extracellular secretory vesicles (V). C, D, E: In 6ppt treated samples, telocytes (blue color) formed a network between muscle cells (red colored). Telocytes established multi-point contact (double arrows) with skeletal muscle fiber (m). Telopode formed a direct contact with the nerve fiber (n). Note epithelium (ep). F, G: In 10 ppt treated samples, telocytes established direct contact (double arrowheads) with skeletal muscle fibers which increased in diameter (m). Note telopodes organized an extensive network and acquired a corrugated appearance (arrows). Note blood vessels (bv) and secretory vesicles (V)
