Movies showing movement of Lycopodium spores and OCCs on the surface of hamster infundibula. (A) Lycopodium spores being picked up by currents above hamster oviductal cilia. (B) Stained OCC traveling over the surface of a hamster infundibulum. (C) Bird’s eye view of the ostium showing entry of a stained OCC. (D) Higher-magnification video showing movement of an OCC into the ostium. (E) Video showing pickup of an OCC that has been recovered from inside an infundibulum. The matrix of the OCC has been compacted and is no longer elastic. (F) Pair of movies showing the effect of cigarette smoke on OCC pickup. The infundibulum on the left has been exposed to sidestream smoke solution, whereas the one on the right was incubated in control medium only.
