Spectral karyotype of iMycEμ-1 cells. A, representative metaphase chromosome spread in SKY display (left) and classification colors (center) and as an inverted DAPI image (right). B, complete, near-diploid tumor karyotype depicting each chromosome in SKY display (left) and classification (right) colors and after staining with DAPI (center): 38–40, XX, Del(4)(C4), Del(6)(D2), Der(9)T(9A4;11E2), Der(11)T(11A4;9E4), Del(12), Der(13)T(13D11;16B5), Der(14)T(14;13), Der(17) T(17D;6D3), +19. The chromosomes are arranged in numerical order from left to right and top to bottom. C, chromosomal translocations that took the form of a reciprocal T(9;11) exchange (left) and three different non-reciprocal exchanges (right).
