Both ctene and tentacle samples that were fixed at least overnight in 4% PFA/1x PBS showed spatial patterns of autofluorescence when excited with 405-nm light.
Ctenophora were readily identifiable in the stomachs of spiny dogfish, at sea upon macroscopic inspection, by their obvious firm-gelatin constitution, small and clear ball-like shape, uniquely (relative to any other spiny dogfish prey) colored pinkish-gray masses, and particularly the ctene rows.
Je otazkou, zda tyto knihy jsou mezi ceskymi neonacisty tak oblibene a tolik jimi ctene, jak predpokladaji media i nekteri politologove.
Conversely, embryos that incorporate multiciliated cells into specialized swimming structures (e.g., ciliated bands or ctene rows) might be expected to take longer to construct their swimming apparatus than embryos that swim with simple, uniciliated cells.
For example, previous chalk-particle marking experiments indicated that the eight rows of comb plates in ctenophores are derived from the four [e.sub.1] micromeres of the 16-cell embryo (7), and deletion of these four micromeres results in the absence of ctene rows and their associated endodermal canal system (8-10).
One characteristic set of structures displayed by most adult ctenophores are the eight longitudinal rows of comb plates (comb or ctene rows) that are used for locomotion.
