GAGs produced among different cell types have structural and compositional differences and structural changes in GAGs are known to occur in cells undergoing morphological differentiation and/or malignant transformations [ 28 29 30 31 ] .

Nevertheless, the collagen IVα1 and laminin B1 genes (as well as several other known marker genes, our unpublished data), are induced normally in lines A and B by day 3-5 even when no obvious morphological differentiation is observed.

The final type of differential resource utilization is morphological differentiation or niche complementarity.

The discoverers chose to recognize the Lac Alaotra population as a separate species in view of its significant morphological differentiation.

There is little genetic or morphological differentiation between North African and European populations, suggesting a recent arrival in Europe.

The high level of morphological differentiation between the genera of Pandanaceae suggests rapid early radiation as seen in other monocot groups.

PSA expression did not alter molecular and morphological differentiation.

In neurons, Tropomyosin 5NM1 mRNA was found to sort to the pole of the neuron elaborating an axon prior to morphological differentiation.

Swarming bacteria undergo morphological differentiation that distinguish them from their planktonic state.

Phylogenetic Relationships among Acantheae (Acanthaceae): Major lineages present contrasting patterns of molecular evolution and morphological differentiation.
