NHU cell lines of finite lifespan were established and maintained in keratinocyte serum-free medium containing bovine pituitary extract, recombinant EGF and supplemented with cholera toxin (KSFMc), using methods that have been described in detail elsewhere [12], [14].
These ingenious cell-level theories were complemented by Hayflick's [ 23, 24] finding of finite cell replication among vertebrate cells allowed to divide without limit in vitro.
He was an acknowledged expert in the mechanisms of red blood cell aging and the reduction of finite red cell life span in patients with cancer.
To evaluate whether cessation of BPA treatment in prior exposed primary HRBEC populations would reverse the activated cell proliferation program of finite-life cells, a primary HRBEC culture (PA151) exposed to BPA, or BPA + curcumin for 40 days, was maintained BPA free and curcumin free for an additional 30 days, labeled with BrdU and harvested for cell cycle analysis.
To apply the finite difference procedure, the 3-D model domain is first discretized into a series of cells and nodes of finite lengths as displayed in Fig. 7.
To favour structural reanalyses and sensitivity analysis, the implicit form of the CBS, i.e., level-set function (LSF) is used in conjunction with the fixed computing grid of finite cell method (FCM).
Due to a limitation of primary cell cultures (finite number of passages), experiments were primarily done as biological replicates rather than technical replicates.
The prediction for the three N-est lines was T-est, suggesting that these cells have an expression profile resembling those of the other established cell lines rather than the cultures of finite life-span cells.
In particular, for large populations of cells, finite and often slow spread of the virus prevents it from infecting a large number of cells per infected cell per unit of time such that a more realistic approximation of the infection process is required.
