title: [Cellular ultrastructure of the superior cervical ganglion of the rat in homo- and heterografts following organ culture of the transplant].
abstract: Transplantation of the superior cervical ganglion of rat, after by organe culture retains ultrastructural integrity of the cells for a longer period than transplantation alone. Whatever the graft--homo or heterograft--neuronal survival is extended. Apart from minuts differences, S.I.F. cells show the same evolution. Ultrastructural features modified after culture always return to their initial state. Numerous after the culture always return to their initial state. Numerous after the culture, the lysosomes disappear in the first weeks following the graft. This cytoplasmic epuration is very important, since it might regenerate the cell and dilate its antigenic properties. Without the graft, the cytoplasmic epuration does not take place; vascularization is considered as a favourable factor of evolution. The association graft-culture has a double impact on survival of SCG cells. The culture initiates a cellular epuration, the graft quickens and perfects the return to a normal morphology.
