The concept of stem-cell plasticity received strong support from a recent observation that
extensively passaged, clonally derived neural stem cells could contribute to hematopoiesis. We …

Sustained blood cell production depends on divisions by hematopoietic stem cells (HSCs)
that yield both differentiating progeny as well as new HSCs via self-renewal. Differentiating …

… In total, 500 000 plaque-forming units (pfu) were screened with the EST clone labeled with
32 P after random priming leading to 12 cDNA clones of different lengths. Among them 10 …

To gain some insight into the structural and functional roles of sterols in higher plant cells,
various plant sterols have been incorporated into soybean phosphatidylcholine (PtdCho) …

… Consequently, the concentration of free sterols (sterols that bear a free p-hydroxyl group
at position C3) in T, leaf tissues became equivalent to that of control leaf tissues (Table 111, …

The 4, 4-dimethyl and 4alpha-methyl sterols of the bacterium Methylococcus capsulatus were
identified as 4, 4-dimethyl-and 4alpha-methyl-5alpha-cholest-8 (14)-en-3beta-ol and 4, 4-…

Signals transduced through the T cell antigen receptor (TCR) are modulated by the src
