The immune cell repertoire is composed of many different cell types that are orchestrated in response to infection and other pathogens that enter the body. As a result, the body can defend itself ...

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 ...

The human small intestine absorbs nutrients while protecting us from potentially harmful microbes. One of the cell types that plays a key role in this protection is the microfold cell (M cell). These ...

Learn how mapping gene-control switches in an ancient sea anemone reveals how identical DNA can produce many different cell ...

Through experimentation with a highly promising anti-aging technique, scientists at the UK's Babraham Institute have demonstrated a new way of turning back the clock in human skin cells. These cells ...

Energy-making chloroplasts from algae have been inserted into hamster cells, enabling the cells to photosynthesize light, according to new research in Japan. It was previously thought that combining ...

Salk researchers report they have discovered a protein called Mitf that mediates the repair function in the peripheral nervous systems of mice. The protein Mitf helps turn on the repair function of ...

Cells are the smallest unit of life. Cells in multicellular plants and animals are arranged into tissues, organs and organ systems. Cells. Tissues. Organs. Organ systems. And the organism itself.

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 ...

This fluorescence image shows chloroplasts (magenta colored) successfully incorporated into the hamster cells, with other features of the animal cell also highlighted (nuclei in light blue and ...
