The stem conducts water, minerals, and food to other parts of the plant it may also store food, and green stems themselves produce food. Hence it seems that they are capable of being genetically reprogrammed. stem, in botany, the plant axis that bears buds and shoots with leaves and, at its basal end, roots.
However, adult stem cells appear to have the potential to generate specialized cells of another tissue under appropriate conditions, for example cells from bone marrow generating cells resembling NEURONS and other cell types found in the brain. An adult stem cell is an undifferentiated cell occurring in differentiated tissue, such as that of BONE MARROW, BRAIN, SKELETAL MUSCLE, LIVER, SKIN, PANCREAS or the BLOOD, with the capacity to yield specialized cell types of the tissue of origin. they are ‘pluripotent’, but they do not have identical properties. Embryonic stem cells and germ cells have the potential to differentiate into almost any or all of the cell types of the body i.e. Discussing K-12 education without the acronym STEM (science, technology, engineering, and mathematics) playing a role has become increasingly challenging. An embryonic germ cell derives from foetal cells destined to be reproductive cells (see GERM LINE). This group of cells can be removed and cultured into embryonic stem cells. An embryonic stem cell derives from a group of cells, the inner cell mass, from a 4–5 day old embryo, called a BLASTOCYST. a central part of something from which other parts can develop or grow, or which forms a support. Ways to produce well-defined populations, avoid oncogenicity, and ensure survival need to be clarified before clinical application can begin.Medical Dictionary for the Health Professions and Nursing © Farlex 2012 stem cell a special kind of cell from an EMBRYO, FOETUS or adult, capable of renewing itself under certain conditions, and of becoming specialized cells that make up the different TISSUES and ORGANS of the body A stem cell remains largely undifferentiated and uncommitted to a specific function, until it receives a signal to develop into a specialized cell (see CELL DIFFERENTIATION). 2 days ago &0183 &32 What is STEMinism STEMinism is a portmanteau that combines the acronym STEM (science, technology, engineering and math) with feminism. However, the complexity of NSCs, neural patterning, and the formation of multiple populations of neurons, astrocytes, and oligodendrocytes warrant the need for intense studies to characterize these cells and to define the microenvironment that will be needed to support them in the diseased CNS. Human embryonic stem cells, with their ability for self-renewal, clonal capacity, normal karyotype, and potential to form NSCs, easily may be the best source of NSCs and progenitors for treating disease. As a range of workers with STEM knowledge and skills becomes increasingly central to innovation and economic growth, a new definition of the STEM workforce that encompasses the diversity and inclusivity of science and engineering is vital to the future of the S&E enterprise and crucial to maintain the broad public support for S&E (NSB 2019a:6). Adult NSC and restricted progenitors are found in the several regions of the CNS throughout life. The neuroepithelial cells generate radial glia that produce fetal and adult NSCs within the central nervous system (CNS). Neural stem cells (NSCs) arise from embryonic ectoderm that forms neuroepithelial cells. Stem cells can be derived from early embryos after the formation of the blastocyst or from fetal, postnatal, or adult sources. There are also aspects of clonality and potency.
The working definition of a stem cell includes self-renewal and the ability to differentiate into several cell types.
