Synaptic specifications in the spinal cord derived co-culture at DIV40. Representative examples of different types of synapses were observed in the culture. Solid arrows in (A) mark the appearance of dense-core vesicles. Apposing small arrows (in A, B, and C) point to synaptic membrane with multiple contact sites. The large solid arrow in (D) points to a typical asymmetric synapse with prominent appearance of postsynaptic density. Scale bar: 100 nm.
