Effect of Hizkia fusiforme Okamura on the proliferation of dermal papilla celIs

This study was conducted to evaluate the hair-growth effects of seaweeds in Jeju by the proliferation of dermal papilla cells. Dermal papilla cells are mesenchymally-derived cells which play a pivotal role in the morphogenesis, regeneration, and growth of hair. Immortalized vibrissa dermal papilla cells were treated with algae extracts such as extract of Hizkia fusiform Okamura, extract of Padina arborescens Holmes, extract of Sargassum thunbergil, extract of Gelidium amansii, and extract of Grateloupia turuturu Yamada. Among them, the extract of H. fusiforme significantly increased proliferation of immortalized vibrissa dermal papilla cells. The results suggest that H. fusiforme extract has the potentiat to promote hair growth via the proliferation of dermal papilla cells.
