Stem cells are cells that have the capacity to self-renew by dividing and to develop into more mature, specialised cells. Stem cells can be unipotent, multipotent, pluripotent or totipotent ...

Bone-marrow-derived multipotent progenitor stromal cells — or mesenchymal stem cells (MSCs) — are the common predecessors of cells of the mesenchymal lineage, such as bone, cartilage and fat ...

In MS, immune system cells mistakenly attack myelin. With stem cell treatment, doctors use chemotherapy to destroy these existing immune cells. Then, they introduce the new stem cells, which are ...

individual stems. Similarly, we classified dicots either as trees or lianas, also in size categories: seedlings (<1 m tall), small saplings (≥1 m tall and <1 cm dbh), large saplings (≥1 cm dbh and <10 ...

From manufacturing to medicine, STEM (science technology, engineering and mathematics) is fundamental to understanding and exploring the world around us. At UCL, our STEM research uncovers the ...

Compared with the dicots, grasses exhibit a relatively conserved but nevertheless ... secondary wall thickness in interfascicular fibers and a significant repression of stem growth (Liu et al., 2014).
