Stem Cell Imaging: Tools to Improve Cell Delivery and Viability

Figure 7

Ultrasound imaging of SCT. Silicon nanoparticles (SiNP) enhance the ultrasound signal of MSCs after cardiac implantation. Ultrasound resolves the needle catheter and the tissue. As shown in (c), the contrast signal due to the backscatter of SiNP highlights the implanted cells. Green signal indicates presence of stem cells. Red arrow highlights the bevel of the needle.
