Term paper on the prospects of stem cell research in human development
The functioning of an adult human body parallels the daily work of a university or other large organisation. During their development, an individual employee is trained for many years, into an ever-increasing area of specialism, with decisions made at each step of the way, making it difficult to change direction or to turn back. While specialists may be adaptable, this is usually only to a degree; it is unlikely that a specialist in one area, for example, marketing, will be instantly successful in cell biology research. Large-scale re-training is difficult, if not effectively impossible, especially after potentially decades of increasing specialisation in a particular role, and so it is with tissue-forming cells in the human body — or rather was, until recently. At the point of conception, the single-celled zygote fertilised egg , through multiple subsequent rounds of cell division and the process of embryonic development, can form any specialised cell, and group into tissues found in the adult body.
Essay on Embryonic Stem Cells Research - Words | Bartleby
A Stem Cell is a similar cell to a multicellular organism. That organism has the ability make an infinite amount of the same type cells. Embryonic Stem Cells are taken from embryos. Embryonic Stem Cells, most not all, are taken from embryos that are grown from fertilized eggs. Cellular Differentiation is when a less specific cell becomes a more particular cell.
Stem cells represent natural units of embryonic development and tissue regeneration. Embryonic stem ES cells, in particular, possess a nearly unlimited self-renewal capacity and developmental potential to differentiate into virtually any cell type of an organism. Mouse ES cells, which are established as permanent cell lines from early embryos, can be regarded as a versatile biological system that has led to major advances in cell and developmental biology. Human ES cell lines, which have recently been derived, may additionally serve as an unlimited source of cells for regenerative medicine. Before therapeutic applications can be realized, important problems must be resolved.
The issue is really not about the stem cell research itself, but about how the knowledge might be used. Stem cell research has the potential to treat a wide range of medical problems. Disclaimer: This work has been submitted by a student.
