     the challenge arises among researchers when hair follicle stem cells (hfscs) derived from a human hair follicle remain poorly expanded in defined culture medium. in this study, we isolated the hfscs and they became confluent after 10 days of cultivation. comparing the viability of hfscs cultured in defined keratinocytes serum free medium (ksfm) in a coated plate and cnt07 medium in an uncoated plate, the number of hfscs cultured in cnt07 was significantly higher at days 2, 4, 6 and 8 (p=0.004). the population doubling time of hfscs was 21.48±0.44 hours in non-coated plates with cnt07 and 30.73±0.75 hours in coated plates with ksfm. our primary hfsc cultures were positive for cd200 and k15 with brownish color. flow cytometry analysis showed that the percentage of hfscs expressing cd200 and k15 were 65.20±3.16 and 72.07±6.62 respectively. after reaching 100% confluence, the hfscs were differentiated into an epidermal layer in vitro using cnt02-3d defined media. hfscs were differentiated into an epidermal layer after 2 weeks of induction. involucrin- and k6-positive cells were detected in the differentiated epidermal layer. this method is a simple technique for hfsc isolation and has a lower cost of processing and labor, and it represents a promising tool for skin tissue engineering.
