Not exact matches

Prof. Jean - Christophe Marine (VIB - KU Leuven): «Unexpectedly, this ability to divide and contribute to melanoma development contrasted with the activities of other cell populations, such as melanocyte stem cells found in hair follicles, for instance.

The diminished ability for cells to grow is strongly associated with the aging process, with the reduced cell population directly contributing to weakness, illness, and organ failure.

Although their function is not completely understood, a special population of cells covering the blood vessels on the brain's surface is thought to contribute to the organ's protection.

These differences between cells with high and low modulations may support the idea that there are two populations of neurons within LIP [22], each of which contributes to timing differently.

Humphreys does caution that the cell population his lab found is responsible for about 60 percent of all organ myofibroblasts, which means that they seem to be the most dominant source, but that there may be other cells that also contribute to the myofibroblast population.

Together, these results suggested that EMT contributes to the establishment of a small cell subpopulation in malignant tumors; this population is then capable of driving the regeneration of the tumor, even when the bulk tumor cell mass is destroyed by therapeutic regimens.

It has been postulated that hypoxia contributes directly to the development of more aggressive cancers by exerting selective pressure on the tumor cell population to favor cells that can survive decreased O2 and nutrients [18 — 20].

Nevertheless, the burst properties reported in this study strongly support the idea that the deeper layers of the SC act as an optimal controller: the systematic organization of peak firing rates and burst durations as function of saccade amplitude along the motor map, the synchronous change in firing rate of recruited cells in the population, and the shaping of the temporal burst profile of a given cell with the currently planned saccade, all contribute to the generation of straight eye - movement trajectories with optimal kinematics.

Some of the long term aims of the studies are (i) to contribute to the understanding of the mechanisms that control cortical development and evolution, (ii) to use the knowledge to grow neural stem cell populations of high purity and viability for therapeutic approaches and (iii) to study how neural stem cells can be activated in vivo.
