Serially cultured keratinocytes from human scalp hair follicles: a tool for cytogenetic studies.
Keratinocytes originating from adult human hair follicles, the most convenient biopsy tissue, can be serially cultured using a combination of two techniques. Primary cultures are established using plucked scalp hair follicles and the bovine eye lens capsule as a growth substrate. Subsequently, cells from these cultures are serially cultivated in the presence of irradiated 3T3 cells as feeders. By this combination of techniques many keratinocytes can be generated from one single hair follicle. These cultures, appropriately treated with colchicine, can provide an adequate number of metaphases suitable for chromosome studies.
