A team of researchers with the Perelman School of Medicine at the University of Pennsylvania has identified three new classes of obesity-related adipocyte progenitor cells in humans. In their paper published in the journal ...
Zebrafish, in contrast to humans, have outstanding regenerative capacities: If brain cells are lost due to illness or injury, they will easily regrow from so-called progenitor cells. With sophisticated methods, researchers ...
