A new study reveals that small cell lung cancer (SCLC) likely begins in basal stem-like cells rather than in neuroendocrine cells, marking a major shift in the understanding of this aggressive disease ...

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 ...

Every second, millions of blood cells are produced in the human body, and about 90% of the cells replaced daily are blood cells. These include red blood cells essential for oxygen transport, platelets ...

When you were first conceived, you were a single cell. From this basic fact, we can extrapolate a few things, most especially that all the cells that make up your body today came (indirectly) from ...

The outer ear is unique to mammals, but its evolutionary origin has remained a mystery. According to a new study published in Nature from the USC Stem Cell lab of Gage Crump, this intricate coil of ...

Stem cells are the body's ultimate shape-shifters, sustaining tissues by balancing two competing demands: maintaining their own population and generating specialized descendants. In many tissues, some ...

Within the next few weeks, thermos bottles containing about a hundred donated human embryos—each composed of only a few cells—will arrive at the renovated labs of Douglas A. Melton, Cabot Professor of ...

Tooth enamel is the hardest substance in the human body, yet once damaged, it cannot regenerate naturally. To overcome this ...

The stem cell-based embryo model (SCBEM) takes advantage of the flexibility of pluripotent stem cells (non-reproductive cells that can give rise to many different types of cells) to resemble that of ...
