Human cells are extremely small and tightly packed – at about 20 micrometers across, roughly one-fifth the width of a human ...

Scientists have crossed a startling new frontier in bioengineering: they can now fabricate intricate three-dimensional ...

Scientists have uncovered a new way embryonic cells divide when conventional mechanisms fail. Cell division underpins all ...

Every cell in a body contains the same genetic sequence, yet each cell expresses only a subset of those genes. These cell-specific gene expression patterns, which ensure that a brain cell is different ...

A faulty ion channel function is a consistent biological feature of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

The mystery of early embryonic communication is starting to be unraveled thanks to a new stem cell-based model.

Prior to using this narrative, have learners create their own model of a cell in their notebooks using whatever background information or experience they might have. While exploring the narrative, ...

During early development, tissues and organs begin to bloom through the shifting, splitting, and growing of many thousands of cells. A team of MIT engineers has now developed a way to predict, minute ...

Researchers at the Francis Crick Institute have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four ...
