ABSTRACT
The aim of this work is to implement a biological model of
neuromuscular junctions to study the mechanisms involved in intra and
inter cellular processes using cell co-cultures. To optimize growth and
development of the neuromuscular junction, cells were seeded on plasma
polymerized pyrrole which has proven suitable for other types of cell
cultures. The cell lines used were motor neuron NG108-15 and skeletal
muscle C2C12. Cells were evaluated according to their morphology and
electrophysiological characteristics. To observe the expression of specific
proteins of the nerve synapse, immunocytochemical techniques were
applied using dying antibodies. Proteins localized in nerve terminals
were dyed and imaged by fluorescence microscopy. Images of cell
co-cultures showed the formation of neuromuscular junctions. The
preparation of neuromuscular junctions described in this work will allow
the study of the mechanisms involved in their functions.
