title: [Factors related to collagen gel contraction in hair follicle organotypic culture].
abstract: To investigate the effects of rat tail collagen, hair follicle dermal papilla cells and hair follicle epithelium cells on collagen gel contraction in organotypic culture.
  
  
  
  The hair follicle organotypic culture was prepared with different concentrations of rat tail collagen, different number of dermal papilla cells and hair follicle epithelium cells in DMEM medium, after cultured for 10 days the diameter of collagen gel was measured.
  
  
  
  The concentration of rat tail collagen, hair follicle dermal papilla cells and hair follicle epithelium cells significantly influenced on collagen gel contraction in organotypic culture (P<0.01). The contraction of collagen gel was negatively related to the concentration of rat tail collagen, while the concentration of dermal papilla cells and hair follicle epithelium cells was positively related to the contraction of collagen gel.
  
  
  
  The key factor influencing collagen gel contraction in organotypic culture is the concentration of rat tail collagen, hair follicle dermal papilla cells and hair follicle epithelium cells.
