The human immune system is like an army of specialized soldiers (immune cells) each with a unique role to play in fighting disease. In a new study published in Nature, led by scientists at the Allen ...

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 ...

Gut support cells communicate with surprising precision – like brain neurons – using tiny extensions to send instructions to the stem cells responsible for maintaining and healing the intestine. The ...

Using a new method to isolate and reprogram plant cells into other cell types, biologists explored how banding patterns that increase the stability of plant cell walls are created and how their ...

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 ...

Orthopedic non-invasive stem cell therapy regenerates damaged tissue rather than just improving symptoms. Autologous stem cell therapy uses cells from your own body, minimizing rejection risks.
