Effects of Artificial Ligaments with Different Porous Structures on the Migration of BMSCs

Figure 1

Gross view of the cell migration model (a-A, a-B, and a-C) and cell migration model with sheets (a-D). The gross view and SEM images of surface morphology of four kinds of PET-ALs (b and c). 5A: the linear density is 5000 D and the knitting method is full-set threading warp knitting; “5000 D” indicates 5000 grams weight of the 9000 meters PET fiber bundles under convention moisture regain; 3A: the linear density is 3000 D and the knitting method is full-set threading warp knitting; 5B: the linear density is 5000 D and the knitting method is part-set threading warp knitting; 3B: the linear density is 3000 D and the knitting method is part-set threading warp knitting; 1 indicates central cylinder (side); 2 indicates annular ring; 3 indicates central cylinder (underside). Scale bars: 500 μm.
