Adhesion assay and number and morphology of colony forming units (CFU). (a) Peripheral blood derived mononuclear cells (PBMNCs) from ten patients and ten controls were cultured overnight, percentages of attached cells were determined. (b) PBMNCs from ten patients and ten controls were cultured for one week after which CFU were formed and counted. In (a,b), the line represents the mean; *P < 0.05). Representative images of (c) a patient and (d) a control culture (the arrows point to a CFU). Notice the smaller size and the lower number of emerging cells when comparing patient CFU to control CFU.
