FIG. 4.

In vivo tracking of human pericytes implanted intramuscularly in SCID mice. (A) Panel of optical images was obtained at different time points for tracking human pericytes transduced with lentiviral luciferase after implantation in thigh muscles of SCID mice. Notably, the signals were remarkably higher in rhNell-1 groups in a dose-dependent manner. (B) Quantitation of the optical signals from implanted human pericytes among different treatment groups. SCID, severe combined immunodeficient; TCP, tricalcium phosphate. Color images available online at www.liebertonline.com/tea
