Inhibition of Melanoma Angiogenesis by Telomere Homolog Oligonucleotides
Evaluation of T-oligos toxicity in internal organs of SCID mice 24 hours after the last IV injection (15 mg/kg BID for 5 days). (a) Bone marrow, displaying a mixture of myeloid and erythroid precursor cells as well as plasma cells. Scattered megakeryocytes are also present. There is no evidence of bone marrow suppression or toxicity. (b) Liver lobule with a central vein surrounded by hepatocytes. The cells display a fixation artifact but otherwise appear normal. There is no evidence of cellular necrosis or apoptosis. (c) Jejunal mucosa displaying normal arrangement of villi lined by tall columnar cells. Both the mucosa and the submucosa appear normal. Fragments of normal pancreatic acinar tissue are seen in the bottom left of the image. (d) Section of the brain showing normal brain architecture with typical neuronal ganglia and scattered small dark glial cells in a pink neuropil background. (e) Normal lung tissue displaying multiple alveoli as well as bronchioles lined with cuboidal epithelial lining. (f) The kidney displays two normal glomeruli that are surrounded by tubules with cuboidal epithelium.
