Recently, the size of the active stem cell pool has been predicted to scale allometrically with the adult mass of mammalian species with a 3/4 power exponent, similar to what has been found to occur for the resting metabolic rate across species. Here we investigate the allometric scaling of human haemopoietic stem cells (HSCs) during ontogenic growth and predict a linear scaling with body mass....

Highly active antiretroviral therapy (HAART) suppresses human immunodeficiency virus (HIV) replication to undetectable levels but cannot fully eradicate the virus because a small reservoir of CD4+ T cells remains latently infected. Since HIV efficiently infects only activated CD4+ T cells and since latent HIV primarily resides in resting CD4+ T cells, it is generally assumed that latency is est...
Although much is known about the activation, proliferation, and function of CD4(+) T cells, little is known about how they survive as resting T cells in animals. Resting T cells have a half-life in animals of more than a week; however, when they are removed from animals and placed in tissue culture their half-life falls to approximately 24 h. In this paper, we show that the survival of resting ...
This study describes the regulation of thymidylate synthetase activity in mouse 3T6 fibroblasts during serum-induced transitions between the resting (G0) and growing state. The specific activity of thymidylate synthetase was about 17 times lower in resting 3T6 cells than in exponentially growing cells. When resting cells were serum-stimulated to re-enter the cell cycle, thymidylate synthetase a...
Growth factor receptors for T lymphocytes, such as interleukin 2 and insulin, are present on activated but not resting T lymphocytes. We sought to determine if insulin-like growth factor I (IGF-I) could act as a growth factor for human T cells and to characterize its receptor on resting and activated cells. Recombinant IGF-I induced two separate functions. It was chemotactic for and increased i...
We have analyzed the expression of homeoproteins of the HOX family in resting and activated lymphoid cells and in neoplastic lymphoid cell lines by the use of monoclonal antibodies (MoAbs) already shown to react with the homeoproteins HOXA10, HOXC6, and HOXD4, respectively. Anti-HOXA10 and C6 MoAbs DIDi not show any reactivity with the lymphoid cells tested, whereas anti-HOXD4 MoAb stained few ...
