Cellular Patterns Determined by Polar Transport

  • T. Sachs
Part of the Proceedings in Life Sciences book series (LIFE SCIENCES)


The topic of this chapter is the control of the patterned placement, or the relative positioning, of various cell types. Polar transport means that the sides of cells are unequal and that the orientation of the cells within a tissue is coordinated. This transport is, therefore, an expression of pattern at a cellular level. Polarity at a cellular level, furthermore, can also be seen microscopically in the arrangement of specialized cells in vascular strands that connect the shoots with the roots. It is asked below whether the transport and the structural expressions of polarity are related and could be used to study one another. This leads to an hypothesis concerning the control of differentiation of cells in longitudinal rows.
