Maintenance of the ES Cell State

Maintenance of the ES Cell State

The cells of the blastocyst inner cell mass only remain pluripotent for a short time. This state of pluripotency and self-renewal can be maintained in embryonic stem (ES) cell culture by adding specific chemicals or growth factors to ensure the cells can continue dividing and later differentiate into different cell types. In some cases, the cells are grown on a feeder layer of differentiated cells, which provides the growth factors and extracellular matrix components necessary for stem cell...

Meristems and Plant Growth

Meristems and Plant Growth

Plants grow throughout their lives; this is called indeterminate growth, and it distinguishes plants from most animals. Although certain parts of plants stop growing (e.g., leaves and flowers), others grow continuously—like roots and stems.

Primary and Secondary Growth in Roots and Shoots

Primary and Secondary Growth in Roots and Shoots

Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.

Inflorescence meristems (IMs) in maize give rise to the tassel and ear.
Genetic studies have advanced understanding but face challenges due to maize's genome complexity.

Purpose of the Study:

To review recent advancements in maize meristem development.
To highlight the integration of single-cell and spatial technologies.
To explore mechanisms of stem cell maintenance and differentiation in SAM and IM.

Main Methods:

Review of genetic studies on maize meristem mutants.
Integration of single-cell and spatial technologies.
Analysis of gene regulatory networks and hormonal pathways.

Main Results:

Insights into stem cell maintenance and differentiation in maize SAM and IM.
