Propagating myosalpinx contractions propel oocytes toward the uterus. Video analysis and STMaps of myosalpinx contractions and egg movements. A) A single video image of an oviduct containing a COM (black dotted circle denotes position of the oocyte in the COM in this frame). Propagating contractions caused indentations in the outer edges of the oviduct, and changes in the edge are summarized in a STMap in B. The white diagonal bands in B indicate the propagating contractions of the oviduct wall. Propagating contractions caused progression of the oocyte along the lumen of the oviduct. The STMap in C tracks oocyte movement as a function of time through the luminal region denoted by the white box in A. Parallel black lines in C trace the position of the top and bottom edges of the oocyte in the STMap of average intensity. The 5-sec (labeled 5 s) time scale shown below C applies for both STMaps B and C. Bars = 100 μm (A and C) and 500 μm (B).
