Fasting increases NAD levels and the NAD/NADH ratio.
"we know that fasting increases NAD levels and the NAD and NADH ratio." (said at 0:36:00)
No published record matching the claim that fasting increases NAD levels and the NAD and NADH ratio was located; this does not prove the claim false.
In aged mouse skin, clearing senescent cells provides little regenerative benefit because the stem cell pool has already been depleted.
"So we have shown in the skin, for example, that with age, um senescent cells do accumulate, but if you clear those cells, you don't get much benefit and that's because by old age, you've depleted the stem cells." (said at 0:38:46)
No published record matching the claim that clearing senescent cells from aged mouse skin provides little regenerative benefit due to exhaustion or depletion of the stem cell pool was located; this does not prove the claim false. While published mouse models from the Campisi laboratory demonstrate that senescent fibroblasts and endothelial cells transiently promote cutaneous wound healing via PDGF-AA secretion (and that their clearance can delay acute wound repair), the specific finding that senolytic clearance fails to rejuvenate aged skin because of stem cell pool depletion has not been documented in the indexed literature.
Unverified means no publication matching the claim was located; it does not prove the claim false. Spotted an error? See the corrections policy - disputes from the people quoted are prioritized.
