Selective elimination of fibroblasts from cultures of normal human melanocytes
In Vitro
|May 1, 1984
Abstract:
The main obstacle to establishing pure normal human melanocytes in vitro is contamination of the cultures by fibroblasts. The obstacle can be overcome by selective destruction of fibroblasts with geneticin ( G418 sulfate). Treatment of mixed cultures with this drug at a concentration of 100 micrograms/ml for two days results in pure cultures of normal human melanocytes.
Insights
Selective destruction of fibroblasts using geneticin (G418 sulfate) enables the isolation of pure normal human melanocytes in vitro. This method overcomes common contamination issues in cell culture, yielding pure melanocyte cultures.
