Figure 1: Expression prolife of CD markers on AMSCs and fibroblasts. Early (≤ 5) passage AMSCs and primary human dermal fibroblasts were harvested and total RNA was isolated. Real-time RT-PCR was conducted to examine the expression of CD49d, CD54, CD81, CDD109, CD146, CD164, and CD172a. Y-axis refers to expression levels normalized to β-actin (*p<0.05).
