| pubmed-article:7574467 | pubmed:abstractText | Fragments of sural nerve biopsy specimens were cultured in the presence of the supernatant of lymphokine-activated killer cells, resulting in the selective outgrowth of cells with bipolar or tripolar morphology, reminiscent of that of Schwann cells. Immunofluorescent staining with antibodies to the S-100 protein, the low-affinity nerve growth factor receptor, and the surface Thy-1 antigen confirmed that these cultures contained more than 99% Schwann cells and no detectable fibroblasts. The mitotic activity of Schwann cells was measured by bromodeoxyuridine labeling, and was increased when the cells were grown in medium with lymphokine-activated killer cell supernatant compared with medium without this supernatant. In the presence of lymphokine-activated killer cell supernatant, Schwann cells could be maintained in continuous culture for a minimum of 8 months. | lld:pubmed |
