Introduction
The research study will bring together people of Embryonic Stem Cells (human embryonic stem cell; HESCs) used as a source to produce or generate cell types of the body. To be used in the treatment of many types of medical doctors currently can not be cured by other treatments. The remedy is called. Changing cells (cell transplantation) or cell therapies (cell therapies), a major goal of many scientists attention. And in the last few years have been published and reported on the progress of the study Embryonic Stem Cells out a lot. One point of interest is. The study of the transformation of stem cells from embryos (embryonic stem cell differentiation) into the cells and tissues of the body. Initially it was because of Embryonic Stem Cells. Cells contain only a few cells are then grown to a cell type in the body, such as nerve cells, muscle cells. Blood cells, etc. To change the state of Embryonic Stem Cells into the cells. There are several factors involved. The one factor that has studied long enough, it is. Stimulants of growth (growth factors), which from past experience that stimulates the growth of different types will affect the transformation of stem cells from the embryo to a cell or tissue, different from
Embryonic Stem Cells
Stem Cells. Embryonic cells have not yet been changed. (Undifferentiated cells) are important features first. Is to divide multiply in culture endlessly. Because after each cell division to daughter cells (daughter cells) at least one cell that retains the properties of stem cells exist. The division continued to increase throughout life. And the key feature of stem cells is second. The ability to develop into specific cell types (specialized cells) of the body to be like muscle cells, nerve cells, etc., stem cells will change in a way which is dependent on the environment both inside and outside the cell. 1-6 is the determining factor To obtain the stem cells can be described briefly as follows. After the fertilized by sperm, egg cells are joined. The new cell is a cell that can grow and develop into different parts of the body further. The new cells formed is called a zygote (zygote), which zygote may be called as stem cells are totipotent stem cells (totus means all) of the cells, the ability to further grow into different parts of the body. 1 block The people found that about 1 hours after fertilization. Zygote will begin to divide, long Clive Savage (cleavage) resulting from cell division first made the cells the two cells that look like each other are identical totipotent stem cells or cell growth Blast Mir (blastomere). If you bring one cell or two cells separate deposited in the uterus that is prepared to be ready to support the implantation of the embryo ago. These cells can develop into an embryo in the end, about three days after fertilization, the zygote can be characterized as the sphere. Cellular growth Blast Meir of 12-16 cells called long-term morula (morula) and on day 4 of these cells are arranged together to form a hollow sphere called growth Blast. Cysts (blastocyst), which is a cell growth Blast Mir 32 cells, and these cells are created in the liquid come together in the middle of the cell, called a growth Blast Seals (blastocoel. ) This term growth Blast cysts are composed of two groups of cells, the first outside wall of the sphere is called Call Flow Blast (trophoblast), which will further develop into a constituent part of. placenta (placenta), and other connective tissues that are essential to embryonic development. The second group of cells are grouped together on the inside of the sphere is called the inner cell mass Inc. (inner cell mass; ICM) cells that develop into a tissue, this latter group stages of the embryo. So Embryonic Stem Cells used in the study thus represents inner cell mass was isolated from embryos term growth Blast cysts. 6 that
the cell's inner cell mass, although the growth. And changes to the tissues of the body confirmed. If you take these cells deposited in the uterus in preparation for pregnancy. These cells can develop into an embryo is. Since none of the cells that develop into the placenta and other tissues needed to conceive one. The ability to grow and differentiate into cell types. Sometimes called Embryonic Stem Cells that pluripotent stem cells (plures mean lots) 6. However, compared to the zygote can be seen that the cells from the inner cell mass has a capacity for growth is limited due. I could not grow to be a component of the placenta and tissues necessary to conceive
of growth stimulants (Growth factors)
are a group of proteins poly peptide. (Polypeptide) has the ability to stimulate or induce the proliferation and cell proliferation in both the condition of the body (in vivo) and in vitro (in vitro) passenger stimulate the growth of any kind can act on the cells. Even a very small amount (about 10-9- 10-11 Molar) and normal tissues in the body, or it will be stimulating growth in small amounts as well. Despite the many similarities between the stimulants of growth hormone (growth hormone) from the anterior pituitary gland. (Adenohypophysis) or with other hormones. But a key difference between the two compounds, this group is two respects, it is the first hormone is made of organ specificity, such as insulin is created by beta cells (b-cells) in the islet of Langerhan. the pancreas, etc., while stimulating the growth of any kind may be generated from cells or tissue types. The second major difference is. After being created, and secretion from the cell that is already built. Hormones are the body
