SUMMARY

Dermal papillae were isolated from human hair follicles and primary cell cultures were established from the papilla explants. The cultured papilla cells spread slowly, initially as a monolayer, and eventually formed multi-layered parallel arrays of fibroblast-like cells. At the edges of expanding colonies the cells were large and flattened and showed a tendency to form clumps. The behaviour of human dermal papilla cells in culture is very similar to that reported in cultures of papilla cells from rat vibrissa follicles.
