Schmidtea mediterranea, a freshwater flatworm (or planarian), has adult pluripotent stem cells spread all throughout its ...

Studying the process of brain formation illuminates just how much of development is a series of tiny miracles. Only a few weeks after a human egg is fertilized, a sheet of cells called the neural ...

A team of scientists has mapped the regions surrounding stem cells in planarians—small flatworms that are famous for being ...

Zebrafish can regenerate sensory hair cells that humans permanently lose, like those in the inner ear linked to hearing and balance. New research reveals two specific genes that control how different ...

Scientists have discovered how leukemia cells outsmart a leading treatment and may have found a way to stop them. Scientists ...

Research groups around the world are working to find ways to implant or grow real biological teeth in a human jaw.

Scientists have used human skin cells to produce functional eggs using a new scientific technique they say could one day help ...

Researchers at Oregon Health & Science University (OHSU) have developed a remarkable new way for making human body cells ...

A human female is born with all the egg cells she will ever have. The possibility for the development of new oocytes is zero. Given this constraint, it is crucial that these gametes remain healthy and ...

They observe how the mobile DNA LINE-1 copies its sequence in human cells, revealing the precise mechanism of the ORF2p gene.

Skin irritation or inflammation "triggers a resting hair follicle to go into a growth phase," Dr. George Cotsarelis told ...

Scientists said Tuesday they have turned human skin cells into eggs and fertilized them with sperm in the lab for the first time—a breakthrough that is hoped to one day let infertile people have ...
