If sulfur is added to the culture once hydrogen production has ceased, the cells, and particularly PSII, can repair; cycles of oxygen production under S-sufficiency and H2 production under S-deprivation can result (e.g., Ghirardi et al., 2000).
Thus, the accumulation of decanoic acid inactivates the cells and ceases the production of sebacic acid.
Upon overexpression of the LETF genes, cell proliferation ceased and the cells exhibited an epithelial morphology, indicating hepatic maturation of hepatoma cells.
By the time they cease division, the cells are filled with glucose in the form of trehalose and glycogen (Lillie and Pringle 1980; Li et al. 2013).
When telomere length reaches a critical point, cellular senescence is triggered, cell division ceases, and the cell dies [ 1, 2].
Immediately before the first cleavage the membrane ceased the vibration, the cell surface became regular, and the hialine layer thickened.
At 35 DAA cell division has ceased, the rate of cell expansion increases and starch accumulation begins.
Within a few weeks following birth, testosterone secretion ceases, and the cells within the testes remain undeveloped during early childhood; during adolescence, gonadotropic hormones from the pituitary gland at the base of the brain stimulate the development of tissue, and the testes become capable of producing sperm and androgens.
In all cases, blood circulation in the affected area ceases, bone cells die, and the marrow cavity becomes filled with debris.
