Stem cell reserve

Stem and progenitor cell number and function — the reserve tissues draw on to replace what they lose.

Clears worn-out cells reduces it.

Senescent cells accumulate in stem cell niches and impair their function. doi 10.1016/j.molmet.2023.101755 · PMC12293478

DNA integrity reduces it.

Genomic instability in the stem pool - hallmark 1 driving hallmark 8. doi 10.1016/j.molmet.2023.101755 · PMC12293478

Protects DNA caps increases it.

Telomerase activity is highest in stem and progenitor compartments - hallmark 2 acting on hallmark 8. doi 10.1016/j.molmet.2023.101755 · PMC12293478

It reduces Cellular aging.

Hallmark 8: stem cell exhaustion. The reserve runs down and tissues lose the capacity to replace what they lose. doi 10.1016/j.molmet.2023.101755 · PMC12293478

It increases Tissue renewal.

The reserve enables the act - stemcell is what regeneration draws on. (doi 10.1016/j.molmet.2023.101755; doi 10.1007/s10522-026-10408-1; PMC12293478). REFUTED ON A SECOND READING. This link was shown by linked steps until a source was opened that does not support it: “In contrast, regeneration after surgical resection of a portion of the liver (partial hepatectomy, PHx) does not require such stem/progenitor cells; the remnant tissue undergoes hyperplasia to recover” — To divide or not to divide: revisiting liver regeneration. Cell Division, 2013, 8(1), 8. doi 10.1016/j.molmet.2023.101755 · PMC12293478

It increases Muscle.

Satellite cells are the muscle stem pool - named directly in the sarcopenia and recovery reviews. doi 10.1016/j.molmet.2023.101755 · PMC12293478

It increases Wound healing.

Progenitor availability sets repair capacity. doi 10.1016/j.molmet.2023.101755 · PMC12293478
