Stem cells drive antler regeneration | Science

A population of stem cells in the antlerogenic periosteum, called antler stem cells (ASCs), appear to be progenitor cells derived from ABPCs and exhibit a much higher proliferation capacity than human bone marrow stem cells (hBMSCs), which are commonly used for stem cell research and clinical applications . In addition, exosomes secreted from ...

Stem cell controversy – Wikipedia

For many decades, stem cells have played an important role in medical research, beginning in 1868 when Ernst Haeckel first used the phrase to describe the fertilized egg which eventually gestates into an organism.

National Institutes of Health grant funds interdisciplinary …

WEST LAFAYETTE, Ind. A team of Purdue University scientists led by Shihuan Kuang has received a $2.5 million grant from the National Institutes of Health to define the role of lipid droplets in muscle stem cell function, a study with implications in both humans and livestock. Lipid droplets are important as a regulatory component of the stem cell. The content of lipid droplets makes the stem cell function better or worse, said Kuang, Cancer Center Chair in Stem Cell Biology and a professor of animal sciences in Purdues College of Agriculture. The human angle will focus on muscle-related disease, aging and injury.

Scientists grapple with ethics of stem cell research – STAT

SAN DIEGO When biologist Alysson Muotri started tinkering with tiny balls of nerve cells in the lab more than a decade ago, his goal was simply to understand early brain development and neurological disease. He didnt realize he was stumbling into an ethical minefield. His University of California, San Diego, team found that when human stem cells were grown into so-called brain organoids in the lab, these tiny 3D structures produced regular waves of electrical activity that resembled what researchers see in a full-size human brain when they place electrodes along a persons scalp. These brain models were a useful tool to better understand conditions such as autism and schizophrenia, which could help researchers develop and test new treatments.
