Genetic Modification of Stem Cells for Transplantation.
Owing to their unique ability to maintain, replenish and repair all tissue types, stem cells hold unparalleled promise for treating diseases outside the reach of conventional medicine.Stem cell, an undifferentiated cell that can divide to produce some offspring cells that continue as stem cells and some cells that are destined to differentiate (become specialized). Stem cells are an ongoing source of the differentiated cells that make up the tissues and organs of animals and plants. There is great interest in stem cells.Next, there are the adult stem cells. Research on adult stem cells has been around the longest and has proven to be the most useful and successful of the different types of stem cells. Adult stem cells are attained from living bone marrow, blood, body fat, brain tissue, and skin. In order to be distinguished as an adult stem cell, the cell has.
List of Cons of Embryonic Stem Cell Research. 1. Its method is generally controversial. Embryonic stem cell research garnered great controversy because it derives cells from human embryos through the process of disassembling the embryo. The component cells are then grown in culture. 2. Its terminology in defining stem cells is deliberately misused.Embryonic stem cells offer hope for new therapies, but their use in research has been hotly debated. Different countries have chosen to regulate embryonic stem cell research in very different ways. Mention embryonic stem cells in the pub and the topic still divides opinion. But what exactly are the ethical arguments and why are they so tricky.
Embryonic stem cells also have limited self-renewals, measured at 2 years. Germ cells can double a maximum of up to 80 times. This limits the research potential of any existing line. The advantages and disadvantages of stem cell research go beyond the ethics of this field. Although the proven benefits of stem cell research are somewhat limited.
