In boost for transplants, kidney tissue grown in lab

Scientists said Wednesday they had grown rudimentary human kidney tissue from stem cells, a key step towards the Holy Grail of fully-functional, lab-made transplant organs.

Tension helps heart cells develop normally in the lab

The heart is never quite at rest, and it turns out that even in a lab heart cells need a little of that tension. Without something to pull against, heart cells grown from stem cells in a lab dish fail to develop normally.

Stem cell-derived 'organoids' help predict neural toxicity

A new system developed by scientists at the Morgridge Institute for Research and the University of Wisconsin-Madison may provide a faster, cheaper and more biologically relevant way to screen drugs and chemicals that could ...

Study reveals the genetic start-up of a human embryo

An international team of scientists led from Sweden's Karolinska Institutet has for the first time mapped all the genes that are activated in the first few days of a fertilized human egg. The study, which is being published ...

Study provides hope for some human stem cell therapies

An international team of scientists headed by biologists at UC San Diego has discovered that an important class of stem cells known as human "induced pluripotent stem cells," or iPSCs, which are derived from an individual's ...

Networking neurons thrive in 3-D human 'organoid'

A patient tormented by suicidal thoughts gives his psychiatrist a few strands of his hair. She derives stem cells from them to grow budding brain tissue harboring the secrets of his unique illness in a petri dish. She uses ...

Tiny spheres of human cells mimic the brain, researchers say

The human brain is a highly organized, three-dimensional mass of cells responsible for our every move, thought and emotion. Snugly housed in the bony confines of the skull, it's also relatively inaccessible, making it difficult ...
