Fig. 1From: Active transforming growth factor-β is associated with phenotypic changes in granulomas after drug treatment in pulmonary tuberculosisMacrophages experience spindloid transformation in tuberculous granulomas. H&E stained granuloma that demonstrates spindloid transformation of histiocytes. This figure provides microhistological examples of: epithelioid transformation of macrophages with elongated nuclei, dashed arrow, top; tapered, spindled macrophages further transformed, solid arrow, left; and collagen deposition, arrowhead, right.
