LDL-lectin and immunofluorescence staining analyses of CD34+-cells a-b: DiI-ac-LDL/lectin double staining of CD34⁺ cell cultures.

<p><b>a</b>: control group, <b>b</b>: ST group. <b>c</b>: phase contrast/Hoechst 33258 staining of purified CD34+ST cultures (cell nuclei stained in blue), same picture as <b>d</b>: CD31 (red)/CD34 (green)/Hoechst 33258 (blue) – immunofluorescence staining showing positive reaction with cultured cells. <b>e-f</b>: CD146 (green)/Hoechst 33258 (blue) – immunofluorescence staining showing low cell numbers with positive staining in the control group (e) but positive reactions in cultured cells isolated from patients with severe trauma (f). All scale bars are 100 µm.
