Fig. 1From: Structural changes and expression of hepatic fibrosis-related proteins in coculture of Echinococcus multilocularis protoscoleces and human hepatic stellate cellsa–f Transmission electron microscopy (TEM, a–c: 30 000×; d–f: 10 000×) images of the internal structure of Echinococcus multilocularis protoscoleces (PSCs). a Normal cell structure of E. multilocularis PSC on co-culture 0 day. b Cell structure of E. multilocularis PSC on co-culture the day 4. vacuoles appearing in the cytoplasm. c Cell structure of E. multilocularis PSC on co-culture the day 4. the perinuclear space widening and mitochondria swelling and vacuoles appearing in the cytoplasm. d the microcilia on wall of E. multilocularis PSC were clearly visible on the 0 day (arrow). The microcilia on wall of E. multilocularis PSC become shorter and cell structure disappearing on the day 3 (e; arrow). The microcilia on wall of E. multilocularis PSC are disappeared and cell structure dissolved on the day 4 (f; arrow)Back to article page
