title: [Experimental study of modified bio-derived material by pluronic F-127 in vitro].
abstract: OBJECTIVE
  To investigate the effects of three-dimentional culture in bioderived material modified by Pluronic F-127 on the growth and function of rabbit periosteal osteoblast in vitro.
  
  
  METHODS
  Bio-derived materials were from fresh pig ribs and were modified by Pluronic F-127. Then rabbit periosteal osteoblasts were cultured in bio-derived materials(group A), in the modified bio-derived materials(group B) and on the plastic surfaces as a control (group C), respectively. During a 7-day period, the status of growth, cell viability and alkaline phosphatase(ALP) activity were measured.
  
  
  RESULTS
  Osteoblasts attached, elongated and grew well on the modified bio-derived materials. There were no significant difference in osteogenesis and ALP activity between group A and group B(P > 0.05). The osteogenesis and ALP activity in groups A, B were less than those in group C (P < 0.01).
  
  
  CONCLUSIONS
  Pluronic F-127 can be used for a carrier for bioactive factors to modify bio-derived material.
