Crypt-base-columnar cells are continuously dividing intestinal stem cells that generate IECs, which are composed by distinct specialised cell types that play different functions: Enterocytes (in the ...

Teeth function not only because of the hard enamel on the surface, but also because they have roots that anchor them firmly ...

An international group of researchers has identified an important mechanism that enables stem cells to evade immune rejection. Their research, published in Nature, sheds light on how these specialized ...

Precision and timing of gene expression is essential for normal biological functions and, when disrupted, can lead to many ...

What the research is about Teeth function not only because of the hard enamel on the surface, but also because they ...

Cells manage a wide range of functions in their tiny package — growing, moving, housekeeping, and so on — and most of those functions require energy. But how do cells get this energy in the first ...

The immune system is comprised of two separate active arms of immunity to provide robust protection against disease. The two separate systems of immunity include the innate and adaptive immune ...

During gestation, the placenta takes on the roles of many of the fetus’ developing organs and serves as a barrier between parent and child. Critical to this is the outermost layer of the organ, the ...

Critical proteins involved in animal stem cell regulation are much older than previously thought, predating the origin of animals that likely evolved more than 700 million years ago. This is the ...

Scientists have made an important discovery about the relationship between hematopoietic stem cells (HSCs) and immune response evasion. Their findings show how certain HSCs have regulatory functions ...
