Increase in differentiated fibrocyte subsets in asthmatic patients with recent exacerbations. Asthmatic patients were divided into those having at least 1 exacerbation in the preceding 12 months and those not having an exacerbation. Numbers of circulating CD45+Col1+ α-SMA+ (A) and CD45+Col1+ α-SMA+CXCR4+ (B) fibrocytes were significantly increased in asthmatic patients with exacerbations to levels greater than those in asthmatic patients without an exacerbation and control subjects. *Significant difference between groups, P < .05.
