Figure 5From: Time course of airway remodelling after an acute chlorine gas exposure in miceTime course of PCNA expression in the epithelium (A) and subepithelium (B) of airways in mice exposed to air (control) or Cl2 gas. Data is expressed as PCNA-positive cells/mm basement membrane. The number of airways evaluated at each time point ranged from 25 to 57. Values are means ± S.E. *significantly different from control (p < 0.05).Back to article page
