GHK-Cu targets these cells directly

TB-500 regulates actin polymerization and recruits stem cells to damaged tissue (Goldstein et al., Expert Opin Biol Ther, 2012)

Other methods like injectables or pills are still experimental and aren't as well studied

The closest structural relative was found to be human CLIC1 (PDB code 1K0O), in which 156 C could be aligned with a root-mean-square deviation (RMSD) value of 0.93 , followed by GSTO1 from Homo sapiens (PDB code 3LFL) (122 aligned C with an RMSD of 2.07 ) and the putative stringent starvation protein A from Burkholderia cenocepacia (PDB code 4QQ7) (122 aligned C with an RMSD of 2.14 ) 12,15

It is found in human blood, saliva, and urine, with plasma levels declining from approximately 200 ng/mL at age 20 to 80 ng/mL by age 60
