bandlet การใช้
- The column of blast cells arising out of each teloblast is known as a bandlet.
- Thus, the segmental boundaries within each bandlet are already specified before all the bandlets come into complete register.
- Thus, the segmental boundaries within each bandlet are already specified before all the bandlets come into complete register.
- Interactions with the q bandlet, however transient, can induce the p fate in the adjacent o / p bandlet.
- Interactions with the q bandlet, however transient, can induce the p fate in the adjacent o / p bandlet.
- O and P bandlets exhibit very different mitotic patterns ( see figure ) which are used to identify them in experimental manipulations.
- Early divisions within the leech embryo result in teloblast cells, which are stem cells that divide asymmetrically to create bandlets of blast cells.
- All five bandlets coalesce into one germinal band on each side of the embryo, extending out from the teloblast towards the head ( in the rostral direction ).
- The M bandlet has been shown to In some species ( i . e . Helobdella triserialis ), the provisional epithelium covering the cells plays a role in inducing the O fate.
- During development, the N and Q bandlets, which eventually have 64 blast cells each, slide past the O, P, and M bandlet, which only have 32 cells.

- Although the MoD was unable to permit a continuous band, this allocation of seven channels was substantially increased to eleven frequency'blocks'( or'bandlets'), integrating the existing channels.
