Testis-derived Sertoli cells have been used to create an immune "privileged" site outside of the testis to facilitate cell transplantation protocols for diabetes and neurodegenerative diseases. In addition to secreting immunoprotective factors, Sertoli cells also secrete growth and trophic factors that appear to enhance the posttransplantation viability of isolated cells and, likewise, the postthaw viability of isolated, cryopreserved cells. It would be beneficial if Sertoli cells could be cryopreserved with the transplantable cell type without deleterious effects on the cells. This report describes a protocol for the cocryopreservation of rat Sertoli cells with rat ventral mesencephalic neurons, neurons from the lateral and medial ganglionic eminences and the hNT neuron cell line, and reports on the effects of Sertoli cells on the the postthaw viability of these neurons. Results of trypan blue exclusion analysis indicated that the presence of Sertoli cells did not deleteriously effect cryopreserved neurons and may improve their postthaw recoverability and viability in general. Specifically, results of the tyrosine hydroxylase immunostaining showed that Sertoli cells significantly enhance the postthaw viability of ventral mesencephalic dopaminergic cells in vitro.
