FIG 1.

Increased numbers of total, differentiated, and activated fibrocytes are found in peripheral blood of asthmatic patients. Numbers of CD45⁺Col1⁺, CD45⁺Col1⁺CD34⁺, CD45⁺Col1⁺ α-SMA⁺, CD45⁺Col1⁺ Smad2/3⁺, CD45⁺Col1⁺p-Smad2/3⁺ and CD45⁺Col1⁺p-AKT⁺ fibrocytes were increased in asthmatic patients compared with those in control subjects. The solid box represents the mean, and the horizontal line represents the median for each group. *Significant difference between asthmatic patients and respective control groups, P <.05.
