Introduction The studies will take cells from the embryo of the origins (human embryonic stem cell; HESCs) used as a source in creating different types of cells, or body parts to be used in the treatment of several types of medical treatment, at present, not be damaged by any other treatment method. Using the method of the treatment, called changing the photo cell (cell transplantation) or cell therapies (cell therapies) is an important goal of many researchers interested in and for a time a few years ago have been published and reported to the progress of the study of the cell.The origins of many from the embryo out. One of the points of interest is the study of the root causes of climate change, from the embryo (embryonic stem cell differentiation) into the cells and tissues of the body, because the cells in the embryo the initial origins from just a few cells consist of cells, and then there is j.Yaplian services to different types of cells of the body, such as nerve cells at a later time. Muscle cells, blood cells, etc., to change the State of a cell from the embryo to the origins of cells. There are several factors that are related by one of the factors that have been studied sufficiently long, it is a stimulant to growth (growth factors), and from the past, it was found that different types of growth stimulant affects to change the State of a cell from the embryo to the origins of cells or tissues in various different.Origins from embryo cells. The cell is a cell that has origins from the embryo cannot be replaced conditions (undifferentiated cells) are the key features first, increasing the number of choices can be split up in the meal, not the end, because the fuel after the split, each cell contains a cell (daughter cells) at least 1 cell that still has the properties of a cell can divide the origins and future of life and the key features during the second cell's origins are able to grow into a specific cell type (specialized cells) of the body such as muscle cells. Nerve cells, blood cells, etc., which are the origins of cell change in any way, it depends on the environment, both internal and external factors that determine cell 1-6. The acquisition, which could explain the origins of cells by in brief as follows: After fertilization by a sperm has to integrate with the egg cell. The new cell, causing the cell that has the ability to grow and develop into different parts of the body further. This new cell called Zygote (zygote), which may be called the Zygote cell is totipotent stem cells origins of type (totus means all) because this cell can continue to grow as various parts of the body I thought was 1. In men, it was found that approximately 1 hour after fertilization. Zygote begins with a clean wet period breaks (cleavage) results from dividing the first cell, cells, cell 2 balls that look like identical totipotent cells called stem cells or blah stony Premier (blastomere) If you bring a cell or two removed cells to deposit in the uterus that is.Prepare to be ready to support embedding of the embryo. These cells are able to grow into an embryo. Day 3 after the Zygote is the principal treaty with a spherical ball tons. The number of 12-16 blah stony bed cell in this phase, called la route (morula) ... stage, and for that, there are 4 of these cells arrange themselves into a hollow sphere. Call blah cysts (blastocyst), a histogram that contains cells blah stony Premier. The number of these cells, 32 cells and creates a liquid that comes together in the klangklum cell, called a histogram (blastocoel) blah seal, this stage includes cells cysts stony blah 2 group by the first group of cells outside of the sphere is called the foplat (the trophoblast), call ต่.Apai will grow to become a component part of the placenta. (Placenta), and other connective tissues necessary for development of the embryo. The second group, cell groups, including a group inside of the sphere, called the inner cell maet (the inner cell mass; ICM) in which the cells grow into the group to various stages of embryo tissues further. Thus, the origins of cells from the embryo that was used in the study, so it means the inner cell maet that is derived from embryo stage blah stony 6 cysts themselves. This inner cell cell maet, although in the end, can grow and change into different parts of the body tissue, but if you take these cells to deposit in the uterus in preparation for pregnancy. These cells cannot grow into a embryo because there are no cells that will grow into a portion of the placenta and other connective tissue necessary to get pregnant 1. From the ability to grow and change into many types of cells. Sometimes called embryo cells pluripotent stem from this root causes cells (plures means a lot) 6. However, when compared to the Zygote will see that cells from the inner cell maet are capable of limited growth because it can't thrive as a component of the placenta and tissue needed for pregnancy.Growth stimulant (Growth factors) เป็นกลุ่มของสารโปรตีนโพลีเปปไทด์ (polypeptide) ที่มีคุณสมบัติในการกระตุ้นหรือเหนี่ยวนำให้เกิดการแบ่งตัวและเพิ่มจำนวนเซลล์ทั้งในสภาพของร่างกาย (in vivo) และในหลอดทดลอง (in vitro) โดยสารกระตุ้นการเจริญทุกชนิดสามารถที่จะออกฤทธิ์ต่อเซลล์แม้มีในปริมาณที่น้อยมาก (ประมาณ 10-9- 10-11 Molar) และตามปกติแล้วในร่างกายหรือเนื้อเยื่อต่างๆก็จะมีสารกระตุ้นการเจริญอยู่ในปริมาณน้อยมากเช่นกัน แม้จะมีความคล้ายคลึงกันมากระหว่างสารกระตุ้นการเจริญกับโกรทฮอร์โมน (growth hormone) จากต่อมใต้สมองส่วนหน้า (adenohypophysis) หรือกับฮอร์โมนอื่นๆ แต่จะมีความแตกต่างที่สำคัญระหว่างสารทั้งสองกลุ่มนี้อยู่ 2 ประการ ก็คือ ประการแรกฮอร์โมนจะถูกสร้างจากอวัยวะที่มีความจำเพาะ เช่น ฮอร์โมนอินซูลินจะถูกสร้างจากบีตาเซลล์ (b-cells) ในบริเวณ islet of Langerhan ของตับอ่อน เป็นต้น ในขณะที่สารกระตุ้นการเจริญชนิดใดชนิดหนึ่งอาจถูกสร้างจากเซลล์หรือเนื้อเยื่อหลายชนิด ความแตกต่างที่สำคัญประการที่สองก็คือ หลังจากที่ถูกสร้างและคัดหลั่งออกจากเซลล์ที่สร้างแล้ว ฮอร์โมนจะถูกลำ
