Cell passaging increases micronucleus in human cells.
“The micronucleus test showed a statistically significant increase of micronucleus from the seventh passage onwards”

Cellular senescence
upin mouse cells1
Cell passaging increases cellular senescence in mouse cells.
“along with the increasing passages, the cells cultured by two methods had similar changes with a decreasing proliferation activity, increasing apoptosis rate, declining migration, diminishing stemness, and obvious senescence.”

Cell passaging decreases blastocyst formation rate in C. hircus cells.
“the blastocyst rate was higher for cells at passages 10 and 20 than passage 30.”

β-galactosidase-positive cells
upin C. hircus cells1
Cell passaging increases β-galactosidase-positive cells in C. hircus cells.
“Irrespective of the donor age, the number of positive cells was higher in later passages from passages 20 to 50.”
