Stem cells capacity to self-renew and differentiate into specialized cell types, endow them with great promises in regenerative medicine. It is believed that the stem cells microenvironment plays a significant role in regulating their fate. However, with e ...
The sediment transport capacity of the Avançon river through the city of Bex in Switzerland is limited. During the October 2000 flood event, water levels rose to danger limits. After the flood, the river channel was completely filled with sediments, with a ...
A major problem in traditional cell culture methods, such as Petri dishes and culture flasks, is the very simplified artificial environment around the cells. Traditional cell culture methods lack features of the native cell niche, such as gradients and cel ...
Systematic hydraulic model tests were performed in a 90° curved channel with an undulated wall at the outer bank. The outer wall consisted of trapezoidal elements of 0.1 m depth and 0.33 m length. Three discharges (150, 180 and 210 l/s) and three bed slope ...
When applied to mountain torrents, sediment transport formulae habitually overestimate the bedload by several orders of magnitude, even if they have been developed for steep slopes. The reason is that the influence of macro-roughness elements, such as larg ...
Biomolecular signaling is of utmost importance in governing many biological processes such as morphogenesis during tissue development where biomolecules regulate key cell-fate decisions. In vivo, these factors are presented in a spatiotemporally tightly co ...
Mesenchymal Stem Cells (MSC) are multipotent stem cells that are predominantly obtained from the bone marrow. These cells have a high ability to differentiate into a multitude of cell types, which are very attractive for tissue engineering and cell therapy ...
Flow conditions and sediment transport capacity in steep mountain rivers are poorly known. One of the main problems is that the presence of macro-roughness elements, such as large relatively immobile boulders, have a strong influence. Experiments carried o ...
Hematopoietic stem cells (HSCs) have a unique ability to self-renew and produce differentiated progeny throughout the entire life of the human body. However, present clinical use of HSCs in regenerative medicine is largely hindered by our limited understan ...
This poster present an experimental investigation of bedload transport in steep slope streams. Accurate technics are used to measure bed elevation and sediment transport rate. The data shows the dynamics of antidunes and the stochastic behavior of bedload ...
