The direct addition of indole-3-acetic acid and sucrose into sterile-cultured segments of tobacco pith via micropipettes has induced cell division and vascularization in a specific arrangement below the tip of the micropipette. The histology of this vascularization is described and it is shown that the orientation of the explant on the basal medium influences callus and bud formation.

Early in spermiogenesis the manchette is rapidly assembled in a distal direction from the nuclear-ring-densities. The association of vesicles of smooth endoplasmic reticulum (SER) and the manchette microtubules (MTS) has been reported. In the mouse, osmophilic densities at the distal ends of the manchette are the organizing centers (MTOCS), and are associated with the SER. Rapid MT assembly and the lack of rough ER suggests that there is an existing pool of MT protein. Colcemid potentiates the reaction of vinblastine with tubulin and was used in this investigation to detect this protein.
