Bibliography 7 Introduction - Stem Cell Research But like many expanding fields of scientific inquiry, research on stem cells raises scientific questions as rapidly as it generates new discoveries. There exists a widespread controversy over human embryonic stem cell research that emanates from the techniques used in the creation and usage of stem cells. Although debates around stem cell research come from varying perspectives, emphasizing differing points of contention, it seems that the controversy surrounding stem cell research comes at the intersection of two primary opposing viewpoints: the high esteem for human life and the right to it, on the one hand; and the desire to alleviate human suffering on the other. And while these two ideas are not in themselves contradictory, in this particular case it is impossible to satisfy one without violating the other. Human embryonic stem cell research is controversial because, with the present state of technology, starting a stem cell line requires the destruction of a human embryo and/or therapeutic cloning. ...read more.


(Source: OCR- Biology revision guide textbook & Wikipedia) Properties The classical definition of a stem cell requires that it possess two properties: * Self-renewal - the ability to go through numerous cycles of cell division while maintaining the undifferentiated state. * Potency - the capacity to differentiate into specialized cell types. Potency specifies the differentiation potential (the potential to differentiate into different cell types) of the stem cell. * Totipotent stem cells can differentiate into embryonic and extra embryonic cell types. Such cells can construct a complete, viable, organism. These cells are produced from the fusion of an egg and sperm cell. Cells produced by the first few divisions of the fertilized egg are also totipotent. As you can see in figure (B.4) * Pluripotent stem cells are the descendants of totipotent cells and can differentiate into nearly all cells, i.e. cells derived from any of the three germ layers. As you can see in figure (B.4) * Multipotent stem cells can differentiate into a number of cells, but only those of a closely related family of cells (e.g. hematopoietic stem cells differentiate into red blood cells, white blood cells, platelets, etc.).As you can see in figure (B.4). * Oligopotent stem cells can differentiate into only a few cells, such as lymphoid or myeloid stem cells. As you can see in figure (B.4). ...read more.


Also, it's my belief that with advancement in this field would have a good impact on our society and might well change it for the better. Other/some people might think stem cell research is bad and should not be promoted as it has a few risks with it and prefer taking the precautionary method but the forget that stem cell research could lead to global development, but most importantly we should all remember that the advancement in this field would/might come handy to save someone precious to you.

    The Cell then separates; each current daughter cell with variation between them. These two cells then separate once again and the result is 4 new sex cells, each containing different genetic information in 23 chromosomes (for humans). Compared to the original cell, the amount of chromosomes has halved, so this type of cell division is sometimes called Reduction Division.
