A Transmission electron microscopy images of mitochondria in lymphoblast of a B-ALL patients and lymphocytes of healthy controls in A1 and A2 respectively (2250X; scale bar = 1 μm). B.1 Representative electron microscopy image of mitochondria in lymphoblast of a T-ALL patient (5000X; scale bar = 0.2 μm). The mitochondria are round and globular. B.2 Representative electron microscopy image of variously shaped mitochondria in lymphoblast of a B-ALL patient (5000X; scale bar = 0.5 μm). C Representative electron microscopy image of hand-mirror shaped lymphoblast in a B-ALL patient (2250X; scale bar = 1 μm). D Representative electron microscopy image of lymphoblast showing nuclear pockets in a B-ALL patient (4000X; scale bar = 0.5 μm). E Representative electron microscopy image of lymphoblast showing vesicular cristae in mitochondria of a T-ALL patient; each arrow depicting cristae in mitochondria (9900X; scale bar = 2 μm). F Representative electron microscopy image of lymphoblast in which the arrow is showing abnormally elongated mitochondria in a B-ALL patient (4000X; scale bar = 0.5 μm). N = nucleus; C = cytoplasm and M = mitochondria
