| Treatment protocol |
Parabiosis was carried out as previously described (Zhang et al., 2021). Female C57Bl/6 mice were pre-screened to minimize body size differences, and were randomly assigned to parabiosis pairs. Isochronic pairs consisted of two 3-month-old or 20-month-old mice and heterochronic pairs consisted of one 3-month-old mouse and one 20-month-old mouse. Pairs were surgically attached and maintained for 3 months. Following 3 months of parabiosis, a subset of mice were euthanized for analysis and another subset were surgically separated. Fascia and skin were sutured closed following separation, and mice were allowed to recover for 2 months, after which they were for euthanized for analysis.

| Growth protocol |
This experiment was approved by the Duke University IACUC. C57Bl/6 mice were obtained from Jackson Laboratories and acclimated to our animal facility for at least 48 h before being subjected to any experimental manipulation. Aged C57Bl/6 mice for parabiosis experiments were obtained from the NIA aged rodent colony. Mice were maintained in a barrier facility in sterilized, ventilated cages and fed standard laboratory chow (LabDiet 5053) and reverse osmosis drinking water ad libitum and maintained on a 12h:12h light:dark cycle. Mice were generally housed socially. Mice were humanely euthanized at the conclusion of each experiment by CO2 exposure followed by cervical dislocation.
