Origin and Continuity of Microtubules

Abstract

One of the first signs of differentiation in many cells is the development of an asymmetric cell form. Examples would include the development of a cilium or flagellum, or the elongation of a cell or part of a cell such as occurs in the development of a muscle cell, nerve cell, or lens cell. Coupled with these changes in morphology are changes of the constituents within the cell; for organelles and inclusions become organized and cytoplasmic streaming is compartmentalized. The changes in form or the development of motile mechanisms are, moreover, a product of intracellular forces rather than a result of differential rates of cell division or localized compression. Since the plasma membrane by itself is not recognized either as a rigid form-producing structure or a potential mechanism of motility, attempts have been made to locate intracellular structures that act in form-development or in motility. One intracellular structure which seems to fit these requirements is the microtubule.
