title: Is delayed micro-graft hair transplantation possible?--evaluation of viabilities of hair follicles preserved in two storage media.
abstract: BACKGROUND
  Preservation of hair grafts for the purpose of delayed transplantation would allow use of thousands of hair grafts at one time.
  
  
  OBJECTIVE
  To evaluate the viabilities of hair follicle units preserved in DMEM and Ringer's solution at 0 degrees C for various periods.
  
  
  METHODS
  Cell cultures and transplantation of hair follicle units into athymic mice were used.
  
  
  RESULTS
  Outer root sheath cells could be cultivated in 95.8% of those follicles preserved in Ringer's solution, and in 86.7% of those preserved in DMEM culture medium (p < 0.01). In 84.5% of those preserved in Ringer's and 72.5% of those preserved in DMEM for 24 h, hair follicles grew well after implantation into an athymic mouse model (p < 0.05).
