Plants form new leaves, flowers and roots at the tips of shoots and roots, in specific growth regions known as meristems. These meristems contain stem cells that divide as needed and form new ...

Using a computer model that reveals how plants grow thicker over time, biologists have uncovered how cells are activated to ...

Most research on plant stem cells focuses on the tips of roots and shoots, where growth occurs in height. But biologist ...

A new method developed by Penn State biologists allows them to turn stripped-down plant cells into other types of cells, similar to the way stem cells differentiate into different cell types.

A new method developed by Penn State biologists allows them to turn stripped-down plant cells into other types of cells, similar to the way stem cells differentiate into different cell types. Using ...

If stem cells were able to multiply uncontrollably, this would lead to uncontrolled growth, as in the case of cancer. WOX5 is ...

Using a computer model that reveals how plants grow thicker over time, biologists have uncovered how cells are activated to produce wood tissue. Understanding the genetic and molecular signals behind ...
