Fig. 7From: IGFBP5 is released by senescent cells and is internalized by healthy cells, promoting their senescence through interaction with retinoic receptorsSerum IGFBP5 in patients undergoing medical irradiation. The picture illustrates the ELISA analysis of IGFBP5 in the sera of 10 patients before and 48 h after an abdominal CT scan. Each patient is identified by a number. The data are expressed as arbitrary units (A.U.). For every patient, the significant difference between samples harvested before and after CT is denoted with ** (p < 0.01) or * (p < 0.05)Back to article page
