Figure 4From: Nicotine exposure during differentiation causes inhibition of N-myc expressionDifferentiated nhpESC express SMA. Cells were stained by immunofluorescence for the fibroblast maker SMA. A: nhp primary lung fibroblasts served as positive controls for SMA; B: undifferentiated nhpESC 4706 served as negative controls for SMA; C: nhpESC 4706 differentiated into fibroblasts were positive for SMA, similar to panel A primary lung fibroblasts.Back to article page
