Combining PLGA Scaffold and MSCs for Brain Tissue Engineering: A Potential Tool for Treatment of Brain Injury

Figure 4

The structural change of the PLGA scaffold in brains with TBI. (a) Procedure to observe PLGA scaffold in the brain with TBI. (b) Nuclear staining shows the planted PLGA scaffold in the brain. Bar = 500 μm. (c) The magnifying picture of the square frame in (b). The PLGA scaffold in the outlined region (dashed line). Bar = 200 μm. (d) Procedure to observe the MSC-PLGA scaffold complex in the brain with TBI. (e) Nuclear staining shows the planted MSC-PLGA scaffold complex in the brain. Bar = 500 μm. (f) The magnified picture of the square frame in (e). The MSC-PLGA scaffold complex in the outlined region (dashed line). Bar = 200 μm.
