In brief, the degradation process leading to a lognormal model is obtained when the amount of degradation or damage that ends in complete failure follows the relationship y t = (1 − ε t ) y t −1, where ε t are small independent random shocks (in our case occurring to each single muscle cell) during progression to failure.
KLF2 is not required for the development of a vascular plexus, but a failure in smooth muscle cell migration is observed in KLF null embryos, causing vascular defects, which lead to bleeding and lethality [18].
Grafts that are not seeded with muscle cells present epithelization failures, because although the epithelium has a high regenerative capacity, the muscle cells by yet unknown mechanisms modulate cell proliferation [ 2].
Efforts aimed at recombinant expression of functional striated muscle myosin isoforms in bacterial or insect cell culture have largely met with failure, although high level expression in muscle cell culture has recently been achieved at significant expense.
However, these materials induce inflammatory reactions, contributing to thrombosis, smooth muscle cell (SMC) proliferation, and neointima formation, processes leading to the failure of vascular substitutes.
Nevertheless, it can have an important impact on the morbidity and mortality of patients, and lead to renal failure due to serum release of toxic muscle cell components.
Vascular smooth muscle cell (VSMC) proliferation remains a major cause of veno-arterial graft failure.
This theory is compatible with the beta cell failure in T2D and also the vascular endothelial and smooth muscle cell senescence, which promotes atherogenesis in hyperglycaemic patients.
Endothelial cell dysfunction could result from increased oxidative stress and lead to vasoconstriction and smooth muscle cell proliferation which could result in NH and contribute over time to access failure.
However, the striated muscle cell proliferation and the increased cell nucleus would result from myocardial hypertrophy, further inducing heart failure.
