When they measured the levels
of upd in the testes of aging males, they found a sharp decline in the well - known self - renewal factor.
Artificially increasing the levels
of upd, results in tumor - like masses of stem cells.

of a chromosome, from one parent and no copies from the other parent.
In an earlier study, Jones had shown that the hub cells secrete the self - renewal factor
upd, which signals neighboring stem cells to maintain stem cell fate, making hub cells an essential component
of the stem cell niche.
