Identification and characterization of telocytes in the uterus of the oviduct in the Chinese soft-shelled turtle, Pelodiscus sinensis: TEM evidence.
Bottom Line: Telocytes (Tcs) are cells with telopodes (Tps), which are very long cellular extensions with alternating thin segments (podomers) and dilated bead-like thick regions known as podoms.Tcs are a distinct category of interstitial cells and have been identified in many mammalian organs including heart, lung and kidney.Samples from the uterine segment of the oviduct were examined by transmission electron microscopy.

Mentions: Telocytes have Tps containing typical podoms that were easy to recognize in our TEM images in the lamina propria (Figs 1 and 2) beneath the simple columnar epithelium of the uterus. These cells meet the ultrastructural criteria for TCs (Fig. 2) and have long (tens of micrometers) and thin (50–200 nm) cellular processes called Tps. The prolongations emerge from the cell bodies and are very long and extremely twisted. The dilated part of the prolongation is clearly visible (Fig. 3). There are mitochondria (Figs 2 and 4) and vesicles in both the cell bodies and the processes (Fig. 4).
