STEM CELL USING HUMAN EMBRYO




Medical researchers have discovered a new way to cure the hazardous disease such as cancer by human embryonic stem cell (HESC). In this case, that method can kill the baby because it takes from blastocyt phase.  That means, we take from 5 days of pregnancy. Early pregnancy is very sensitive so, we may not create a new individual. There are three reasons that make it dangerous for the baby.
The main reason is that the baby fails to complete the development of placenta and membrane cell. HESC extracts the blastocyt with a damage patient cell. The process to create a new healthy twin patient tissue needs huge energy. According to researchers, the baby will be exhausting. If that happens, the baby miscodes placenta and membrane cell as harmful substances and destroy them. Without those substances, the baby cannot absorb nutrition and form an impact protection. That is why the baby cannot survive. Even though the baby can survive, the baby will be disabled.
The second reason is that HESC can cause cancer. Embryonic stem cells are versatile but they can also become malignant. Malignant cells will often have increased numbers of mitoses. Mitoses are the scientific term for nuclear cell division of malignant cells which are typically aggressive. Their potential for causing cancer is a real concern for researchers. The editor of the journal stem cells made a startling admission last year,” I continue to think that clinical application is a long way off. Prior to clinical use of embryonic stem cell has a huge potential to become a malignant cell and it is dangerous for the baby. The baby will be died because it is attacked by the cancer cell.”
HESC is also dangerous for the baby because the baby cannot reconstruct the extracted cell well. When we extracted the patient somatic cell through the embryo, the embryo’s DNA will be transferred to the patient somatic cell. The movement of it causes lacking of embryo’s DNA. In this condition, the embryo may reconstruct the cell. But, in the early pregnancy, there are many things that need to be form as an organ. That is why the baby cannot maximize the reconstruction of DNA. According to the medical fact, the normal individual needs a hundred percent of DNA. If the baby cannot produce the complete DNA, the baby will die or be born abnormally.  
In conclusion, HESC is dangerous because it can inhibit the baby’s development. Therefore, HESC should be banned and changed with the other method such as stem cell using bone marrow because HESC makes the baby die in the very early pregnancy. It also makes the baby being disabled if the baby survives.
