Fig. (2) Caspase 3 activity in human fetal lung epithelial cells.
Caspase-3 activity measured in cell lysates of immature and mature
human fetal lung epithelial cells following cytokine exposure.
Values are normalized for protein concentration and expressed as a
percentage of 6 hour fetal control. Cytokine exposure resulted in an
increase in caspase-3 activity in immature cells at all time point and
in mature cells at 24 and 48 hours (*p<0.05). Cytokine-exposed
immature cells had increased caspase-3 activity compared to
cytokine-exposed mature cells at both 6 and 24 hours (#p<0.05).
