We previously reported on hair-shaft elongation from human scalp and mouse skin in Gelfoam
histoculture [9, 10]. However, in the Gelfoam1 histoculture of human scalp skin, hair- shaft growth was 0.86 ± 0.18 mm over 5 days [9] and 0.7–1.10 ± 0.22 mm over 5–14 days of thehistocultured mouse skin [10]. Isolated human hair follicles in Gelfoam histoculture grewonly 0.49 ± 0.06 mm for 5 days [9].The present report demonstrates improved hair shaft growth of isolated hair follicles on Gelfoam.
