A reexamination of the role of microfilaments in neurulation in the chick embryo
The data indicate that only the later aspects of neurulation may require microfilaments, and that certain neuroepithelial cells, particularly those that normally wedge with median furrowing and elevation of the neural folds, become (and remain) wedge‐shaped in the absence of apical microfilament bands.

The remodeling of synaptic extracellular matrix and its dynamic relationship with nerve terminals at living frog neuromuscular junctions
Extensive remodeling in not only the nerve terminal but also the synaptic extracellular matrix in adult living frog NMJs is shown and results suggest that nerve terminals retract before the synaptic Extracellular Matrix. Expand
Cellulose biogenesis in bacteria and higher plants is disrupted by magnetic fields
Ce phenomene est mis en evidence chez une plante, Avena sativa et chez un bacterie, Acetobacter xylinum. Expand

To examine de novo differentiation of the active zone, ectopic neuromuscular junctions were studied in adult frog muscles and found that before junctional folds are observed with freeze fracture, many active zones are parallel to each other and to the long axis of the nerve. Expand

Results suggest that synapse-specific extracellular matrix molecules can be induced de novo at new junctional sites and binding of PNA at ectopic neuromuscular junctions which were initially extrasynaptic and hence unrecognized by PNA is shown. Expand
