Highly Variable Genomic Landscape of Endogenous Retroviruses in the C57BL/6J Inbred Strain, Depending on Individual Mouse, Gender, Organ Type, and Organ Location

Figure 4

Variations in MLV-ERV landscapes in the immune organs (primary—thymus and secondary—spleen) of C57BL/6J inbred mice of different ages. Substantial variations in the MLV-ERV landscapes were observed in the thymus and spleen genomic DNA among all four age groups (5, 8, 12, and 20 weeks) of the C57BL/6J male mice. No age-specific or immune organ-specific I-PCR amplicon banding patterns were identified. For better resolution, a reversed image of the selected area is shown. Wk: week; SM: size marker.
