New research has identified yet another way that spaceflight tampers with the human body. A study involving samples flown on ...

A human cell culture model of the lung’s most important immune cells, alveolar macrophages, helped make a key finding that is prompting researchers to rethink the role of another immune protein.

Scientists have developed a new model to study an early stage of human development, using human embryonic stem cells.

A researcher holding human embryonic stem cell cultures in 2004. In the new research, scientists use human stem cells to make models similar to human embryos. The models cannot develop into ...

Human pluripotent stem cells can develop into any cell of the body and can be coaxed to become neurons to model brain diseases in a lab dish.

A 6-day-old embryo model from Jacob Hanna’s lab in Israel has structures akin to ones found in human embryos 12 days after fertilization. Those structures include a ball of cells (top, purple ...
