Evaluation of the effect of age of the younger mice on the rejuvenation of the older mice by heterochronic parabiosis
Figure 1. A 67-week-old mouse was joined to a 4- or 8-week-old mouse. Although the mice pairs were joined for 2 months, the fur around the nose and head of the older mice (white arrows) was sparser than that of the younger mice (grey arrows), and no apparent rejuvenation was achieved in either case after 2 months.
