For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like structure, from a single starting stem cell population and without direct genetic manipulation. The models ...
In science, ethical guidelines ensure that research takes place in a way that respects public trust and is conducted responsibly. Traditional ethics approval procedures work well for projects following established practices, ...
A study published in Cell Research advances a central idea in stem cell biology by identifying a checkpoint that controls the identity of many different types of stem cells across developmental stages. For nearly two decades, ...
Stem cells are the body's ultimate shape-shifters, sustaining tissues by balancing two competing demands: maintaining their own population and generating specialized descendants. In many tissues, some early descendants can ...
Swallowing is a fundamental human function that supports nutrition and communication. Damage to swallowing muscles can reduce quality of life and even lead to aspiration pneumonia or malnutrition. Many patients suffer from ...
A new study has uncovered how an exceptionally scarce protein can orchestrate the assembly of large-scale gene-silencing structures inside cells, and what happens when that process breaks down. The findings, published today ...
Hair regrowth treatment may soon take a major leap forward, as researchers in a recent study have successfully grown complete, fully functional hair follicles outside of the living body, in a dish. This was made possible ...
A new study has found that L1td1, a protein evolutionarily co-opted from the Long interspersed nuclear element 1 (LINE1) retrotransposon, functions as a critical "gatekeeper" restricting pluripotent stem cells (PSCs) from ...
One of the most enduring goals in regenerative medicine is deceptively simple: replace a person's damaged or dying cells with healthy new ones grown in the laboratory.
Skeletal muscle stem cells in hibernating Syrian hamsters preserve their ability to function by suppressing their activation during the hibernation period, a research team led by Hiroshima University has shown. This insight ...
