Stem cells function as a source of new cells to grow or replace specialised tissues. To perform this function, these cells must divide to renew themselves, while some of their descendants eventually ...

Plant stem cells, as in animals, are maintained in specialized microenvironments, which are known as stem cell niches, where local signals from organizer cells act to prevent stem cell differentiation ...

Human chromosomes behave in much the same way as those of rodents, primates, and other close evolutionary cousins. But researchers don’t know whether those similarities might extend to distantly ...

WEST LAFAYETTE, Ind. - Purdue University researchers have developed an algorithm that quantifies and analyzes shape changes in puzzle piece-shaped plant cells, providing insights into the small-scale ...

A mutant seedling revealed how plant tissues scatter incoming light, allowing plants to sense its direction and move toward it. On a shelf lined with terra cotta pots, herbs bend their stems toward ...

At first glance, plant and animal cells have a lot in common: they’re both highly organized, keep their DNA tucked away in an envelope, and are kinda juicy inside. But plant cells have evolved some ...

Plant cells are surrounded by an intricately structured protective coat called the cell wall. It’s built of cellulose microfibrils intertwined with polysaccharides like hemicellulose or pectin. We ...
