Mount Sinai researchers have published the first organ-wide human skin spatial atlas from across the body. It provides an unprecedentedly detailed view of healthy human skin, revealing cellular ...

Northwestern Medicine scientists have discovered that one of the body's most fundamental biological processes—how red blood ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

Scientists found that embryonic skin cells “whisper” through faint mechanical tugs, using the same force-sensing proteins that make our ears ultrasensitive. By syncing these micro-movements, the cells ...

Collagen, the protein that builds skin, bones, tendons and organs, exists inside cells as a liquidlike droplet rather than the long, rigid rod seen in textbooks over the last half-century, according ...
