Abstract
|
|
|
|
Structure of marginal band (MB) of microtubules and their assembly process within immunocytes of Blattella germanica have been investigated via transmission electron microscopy, lytic medium treatment, and immunofluorescency. Of particular interest is the lytic medium treatment that produces a remarkable result for the features of MB. Formation of MB begins with two microtubule bundles originated in a microtubule organizing center (MTOC). Each bundle grows in an opposite direction drawing more or less of a circle in outline. Their growth continues until each bundle comes back to the starting point at MTOC, hence establishing two circular bundles upon completion. Comparison of a number of microtubules at different stages also supports this scheme. Microtubules in a bundle have increased approximately double in number beyond the overlapping point. This report on the process of MB formation is a follow-up to that revealing their presence in B. germanica.
