Use of Self-Assembling Peptides to Enhance Stem Cell Function for Therapeutic Angiogenesis

Figure 6

Fluorescent immunohistochemical staining for stem cell markers CD105, CD90, and CD29 from ischemic hindlimbs injected with a combination of MSC, RADA, and RSP (10x magnification). RSP is proposed as being stronger in recruiting endogenous MSCs and therefore the combination of MSCs with RADA and RSP showed the presence of both injected MSCs (yellow stain) and endogenously recruited MSCs (red stain) in the merged images for the different markers at different time points.
