Tracking an organism's development, cell by cell

Scientists at the Stem Cell Research program at Boston Children's Hospital and Dana-Farber Cancer Institute/Harvard Medical School have devised a mouse model that lets researchers track every cell in the body, from the embryonic ...

Clear sight in the data fog with PAGA

Experimental molecular assays with single-cell resolution generate big and complex data. Researchers at Helmholtz Zentrum München and the Technical University of Munich are now presenting their computer algorithm PAGA. They ...

Feedback loop maintains basal cell population

Notch – the protein that can help determine cell fate – maintains a stable population of basal cells in the prostate through a positive feedback loop system with another key protein – TGF beta (transforming growth factor ...

Lineage trees reveal cells' histories

In recent years, a number of controversial claims have been made about the female mammal's egg supply – that it is renewed over her adult lifetime (as opposed to the conventional understanding that she is born with all ...

Last universal common ancestor more complex than previously thought

Scientists call it LUCA, the Last Universal Common Ancestor, but they don't know much about this great-grandparent of all living things. Many believe LUCA was little more than a crude assemblage of molecular parts, a chemical ...

Scientists offer way to address 'age-old' questions

Scientists have devised a method to measure the impact of age on the growth rates of cellular populations, a development that offers new ways to understand and model the growth of bacteria, and could provide new insights ...
