On the other hand, Yousef et al[64] recently found that the decline in stem cell function with age was largely due to biochemical imbalances in the cell niches, demonstrating that aging imposes an elevation in transforming growth factor (TGF-) signaling in the myogenic niche of skeletal muscle and in the neurogenic niche of the hippocampus. Halldorson et al[27] tried to identify poor donor/recipient matches that could help to direct allocation of organs to recipients in which the survival is greatest, maximizing the benefit of donor livers. When many people first got their driver's licenses, there was often an opportunity to . The hepatocyte proliferative response to epidermal growth factor (EGF) is clearly increased in young rats compared to old animals, suggesting that aging impairs hepatocyte responsiveness to growth factors[53,60].

Among those senescence markers that have been studied is the abovementioned telomere length; others include the senescence marker protein-30 (SMP-30), which has shown good results in animals that have not correlated with results in humans; CDKN2A/p16INK4a, which is a good predictor of long-term graft function in renal transplantation but has not yet been studied in liver models; the cyclooxygenases 1 and 2 (COX-1 and COX-2); the cell proliferation marker Ki-67; endoplasmic reticulum chaperone levels; and cytochrome p450 mRNA expression[67]. A standard criteria donor (SCD) liver comes from a deceased donor who is declared brain dead. The results indicated that these factors were hepatitis C as the etiology of liver disease, MELD score higher than 20, donor serum glucose level higher than 200 mg/dL at the time of liver recovery, and skin incision to aortic cross-clamp time longer than 40 min in the donor surgery. Timchenko NA. In a retrospective analysis performed using data obtained from the UNOS, Reese et al[11] found that performing LTs with donors who were 45 years old increased the risk of graft failure at 90 d after transplantation. Core tip: Because of a donor shortage, the use of grafts from old donors has become widespread. Studies that analyze impact of donor age on liver transplant outcomes. Moreover in the older donor group we did not observe any case of primary non-function and patient survival was not affected. In their findings, the serotonin receptor agonist resulted in increased systemic VEGF availability, up-regulating the number and size of endothelial cell fenestrae, improving hepatic blood flow, and therefore enhancing the hepatic regenerative capacity. Lthold SC, Kaseje N, Jannot AS, Mentha G, Majno P, Toso C, Belli DC, McLin VA, Wildhaber BE. Krause S, et al.
