By immunohistochemical staining, we could confirm some of these gene products like MTA2, ESAM, and LGALS1 in primary tumour and in metastasized cells in the lung of the two clones (Fig. 4a–c), but CTTN only in primary tumour sections not in metastatic cells of the lung (Fig. 4d). The gene discussed is LGALS1; the disease is neoplasm.
