Frey and his colleagues made use of mathematical models to analyze the complex interplay between ecological factors and population dynamics, and were able to demonstrate that populations can indeed respond in a coordinated fashion to chemical information even when the signal molecules are generated by only a subset of the cells.

He is also interested in understanding the transcriptional regulation of lineage choice between different stem cell populations that occurs in the blastocyst.

However, no differences between the use of CD4ζ - modificed and unmodified cells were observed for HIV infection levels and CD4 T - cell levels, although the data does indicate that both NK cells populations can inhibit HIV replication and prevent CD4 + T - cell depletion in vivo.

«In the case of morphogenesis, these are interactions between cells; in the case of population genetics, the interactions are between genetic polymorphisms,» said Shraiman.

Assuming that the findings of the review reflected a causal relation between smoking cessation and risk of all cause mortality, we further investigated the data by constructing life tables for a hypothetical group of 100 patients aged 65 years with early stage lung cancer to estimate how many deaths would be prevented by smoking cessation within the non-small cell lung cancer and small cell lung cancer populations during five years.

No Association Between Response Rates and Survival in Newly Diagnosed Multiple Myeloma: Results of a recent meta - regression analysis of 63 randomized clinical trials out of Greece concluded that there was no association between conventional response outcomes, such as complete response (CR) or very good partial response (VGPR), and overall (OS) or progression - free survival (PFS) in patients with newly diagnosed multiple myeloma in populations of patients who received stem cell transplant and those who dBetween Response Rates and Survival in Newly Diagnosed Multiple Myeloma: Results of a recent meta - regression analysis of 63 randomized clinical trials out of Greece concluded that there was no association between conventional response outcomes, such as complete response (CR) or very good partial response (VGPR), and overall (OS) or progression - free survival (PFS) in patients with newly diagnosed multiple myeloma in populations of patients who received stem cell transplant and those who dbetween conventional response outcomes, such as complete response (CR) or very good partial response (VGPR), and overall (OS) or progression - free survival (PFS) in patients with newly diagnosed multiple myeloma in populations of patients who received stem cell transplant and those who did not.

Pair-wise comparisons (FDR < 0.05, > 1.5-fold expression levels) were performed between the following populations of cells to reveal non-redundant, significant changes in gene expression.

To define the phenotype and function of specific cellular populations involved in the cross-talk between cancer and immune cells we make use of both flow - cytometry and mass - cytometry.

Thus we examined whether FGF signalling could alter the dynamics between the V + and V − states within the S + population by culturing HV cells in the presence of the FGFR inhibitor PD173074 [41] for 48 h.

No significant differences were seen between the normoxic and hypoxic anoikis - resistant populations collected from MCF7 cells and a single significant gene change (PIP) was seen in T47D (Table 1) suggesting that the CSC - enriched population remains virtually unchanged following hypoxic culture and the increase in MFC, HFC, and tumor initiating cells is, therefore, due to expansion of the population, perhaps by increased symmetric self - renewal of the CSC or de-differentiation of early progenitor cells, rather than simply the acquisition of anoikis resistance in non-CSC.

Both vitamin A and D up - regulate expression of a population of immune cells known as toleragenic FoxP3 + regulatory T cells (Tregs), which engender balance between the Th1, Th2, or Th17 arms of the immune system, all of which can perpetuate autoimmunity when their exquisitely fine - tuned balance is disrupted.
