Depletion of CD4+CD25+ cells did not restore the antigen-driven expansion of T cells carrying the studied rearrangements, suggesting that suppressor activity induced by therapy is apparently not involved in the failure to proliferate of the studied cells.
Our data are further corroborated in human fulminant hepatic failure, in which, upon 80% loss of hepatocyte compartment, huge numbers of proliferating EpCAM+ biliary epithelial cells are observed (Hattoum et al., 2013).
Together, these results demonstrate that the deletion of Ddb1 leads to acute loss of proliferating HSPCs and their downstream progeny, resulting in bone marrow failure and lethality.
Mex3-1 inhibition decreased numbers of post-mitotic progenitors cells and concomitantly increased numbers of proliferating neoblasts, including three lineages specified within that population, causing failure of regeneration and tissue homeostasis.
This defect in synthesis is the only means by which EBV plasmids are detectably lost from a population of proliferating cells; missegregation, however, can contribute to a daughter cell's failure to acquire a plasmid.
Four of the tumour-bearing muscles in the test group (three rectus and one gastrocnemius) contained fibrotic foci with central islands of proliferating tumour as determined by BrdU staining, but these treatment failures were confined to two rodents.
Ki67 is a marker of proliferating cells.
It is axiomatic: When there is no penalty for failure, failures proliferate.
Our observations also show that in the presence of serum and growth factors, EVL is required for the growth of untransformed ER-Src cells and suggest that the failure of these cells to proliferate in the absence of growth factors could be due, in part, to the lack of EVL expression.
In an attempt to identify the reasons for the general failure of TD cells to proliferate, we have explored the consequences of acutely suppressing specific CKIs in myotubes.
