“This is a spatial and temporal regulation leading to the gradient we’ve seen,” Zhou said, “Our results uncover a molecular linkage between the epidermis and shoot stem-cell homeostasis. We find that ...

"Specialized plant cells regain stem-cell features to heal wounds." ScienceDaily. ScienceDaily, 3 May 2019. <www.sciencedaily.com / releases / 2019 / 05 / 190502143509.htm>.

Stem cells, found at the tips of the shoots and roots of plants, can transform themselves into other types of cells and develop new organs, such as leaves, fruits, and twigs, throughout the entire ...

Scientists reported Wednesday that they genetically modified stem cells to grow skin that they successfully grafted over nearly all of a child’s body – a remarkable achievement that cou… ...

Stomata are minute openings found in the epidermis of leaves, stems and other plant organs. Stomata allow gases such as carbon dioxide, water vapour and oxygen to diffuse into and out of the ...

Over time, however, they mature and are replaced by newer cells—remember, the epidermis' cells turn over every month. And those newer cells all come from a small population of stem cells.

LAMB3 is one of three genes that encode a laminin protein that links the epidermis to the dermis. Mutations in other genes cause JEB too. In the United States, prevalence for all types of JEB is 1 ...

The epidermis, the outermost layer of human skin, forms a protective interface between the body and its external environment, preventing water from escaping and microbes and toxins from entering.
