Fig. 5From: Senescent thyrocytes and thyroid tumor cells induce M2-like macrophage polarization of human monocytes via a PGE2-dependent mechanismThyroid cells with M2-like polarizing activity express the PTGS2 gene and secrete PGE2. a qRT-PCR analysis of PTGS2 in senescent (STh) and proliferating thyrocytes (PTh), and in M2-polarizing thyroid cell lines (K1, BCPAP, HTC/C3). b PGE2 levels, determined by ELISA, in the conditioned medium from senescent (STh) and proliferating thyrocytes (PTh), and from polarizing and non-polarizing thyroid cell linesBack to article page
