  At high magnification these are cylindrical fibers,
  在高倍放大后 这些纤维是圆柱状的
• 
  
  there's lots of space in between them,
  两两之间有很大的间隙
• 
  
  and so you could fill these fibers up with cells
  你可以用细胞来填满这些间隙
• 
  
  and cells would cling to the fibers
  细胞会附着在纤维上
• 
  
  and potentially grow within this scaffold.
  在这种像脚手架一样的框架中生长
• 
  
  This is a different kind of architecture of a scaffold
  它和脚手架的结构不同
• 
  
  but made of the same sort of material,
  但都是由相同的材料制成
• 
  
  synthetic polymers.
  即合成高分子聚合物
• 
  
  Here instead of making fibers,
  这里不是纤维
• 
  
  a porous structure was made that looks like a sponge.
  而是一种多孔物质 看起来像海绵
• 
  
  There are the walls of the material that give it substance,
  由这种物质组成构架
• 
  
  and there are lots of spaces in between much larger
  其间充满各种比细胞大得多的空隙
