Today, I will tell you about Stem cells. To show it easier, I will give you 6 questions called “5W1H”. The answer of them wil help me.

The first W, What is stem cells ? Stem cells are pluripotent cells present in all living organisms. These cells can differentiate into any type of cell, including nerves and cardiac muscle. Stem cell are “undifferentiated biological cells that can differentiate into specialized and can divide(through mitosis) to produce more new cells of the body. They are blank cells/precursor cells that can give rise to multiple tissue types such as skin cells, muscle cells, nerve cells and much more...

The second W, Where do Stem cell come from ? Stem cells can be obtained from three different sources. The first and most controversial source is an embryonic cell that comes from a three to five day old blastocyst, which is a ball of undifferentiated cells that forms after an ovum is fertilised. These are often created by in vitro fertilisation for implantation in infertile woman or gestational carriers in order for these women to become pregnant. Some of the “extra” unused blastocysts are frozen for possible future use. These blastocysts and aborted foetuses have been used to create embryonic stem cell lines. The second very rich source of stem cells is the umbilical cord. Blood cells from the cord blood of a newborn infant can be used immediately or frozen for later use by that infant, close relative, or unrelated recipient. The third and most recently discovered source is adult stem cells. Adult bone marrow or blood cells can be artificially induced back into unprogrammed cells and then can be used as stem cells to form other somatic cell lines, such as nerves and muscle cells. The origin of the first argument is the source and process for producing some stem cells, specifically embryonic stem cells. Often, people jump to the conclusion that all stem cells are derived from embryos meaning that a human life must be sacrificed in order to create a stem cell line. Potentially, one life could save millions of people from illnesses and deaths. Another controversy around stem cell use is the movement to create siblings who can serve as identical-matched donors. Umbilical cord blood is the typical tissue used in these situations, but occasionally supplemental bone marrow must be used. The use of in vitro fertilisation and preimplantation genetic diagnosis has allowed parents to create compatible foetuses who do not have the sibling’s genetic disease. Some people have raised moral and religious objections to creating a horde of embryos that will just get discarded without a thought if they do not meet the right criteria to help the sick sibling. Should a family create a child just to help a sibling, or should they have a baby because the new child would also be special to them? The use of umbilical blood cells was not discouraged as long as the newborn infant was not placed at physical risk during delivery. The ongoing controversy over discarding unmatched embryos may be resolved by using the newly discovered adult stem cells. The discovery of adult stem cells has excited the scientific community, but these cells still have their problems. An already differentiated body cell must be genetically reprogrammed back into an unprogrammed pluripotent cell that looks like an early embryo. The advantage is that an embryo does not have to be created, but the disadvantage is that cancer-causing oncogenes and retroviruses must be used to “unprogram” the adult cells. This could lead to an increased risk of cancer in already compromised patients. Scientists working in tissue engineering and regenerative medicine hope to someday use the cells from the intended recipient to create a new custom designed cell type or even a perfectly matched organ to replace damaged tissue. With new knowledge comes a new concern about the misuse of this information. There are growing fears that stems cells would be used not only to clone new organs but could be used to clone new preferred populations. Some are concerned about the unintended consequences of new cancers or illnesses. Others argue that we should not mess with human life, and we should not be trying to play God. The potential social and economic benefits of the many that could be saved far outweigh the detriments of loss of life or limited funding. Adult and umbilical cells are emerging as the more advantageous sources with the fewest ethical controversies. Umbilical cells would be even more acceptable if genetic matches could be determined before an ovum is fertilised and an embryo is formed. That way an innocent life would not need to be sacrificed. It is essential that scientists pursue stem cell research while valuing all life.

Hôm nay, tôi sẽ cho bạn biết về tế bào gốc. Để hiển thị nó dễ dàng hơn, tôi sẽ cung cấp cho bạn 6 câu hỏi được gọi là "5W1H". Câu trả lời của họ wil giúp tôi.W đầu tiên, tế bào gốc là gì? Tế bào gốc là pluripotent tế bào hiện diện trong tất cả các sinh vật sống. Những tế bào có thể phân biệt vào bất kỳ loại tế bào, bao gồm các dây thần kinh và cơ tim. Tế bào gốc là "undifferentiated sinh học tế bào có thể phân biệt vào chuyên ngành và có thể phân chia (thông qua nguyên phân) để sản xuất các tế bào mới hơn của cơ thể. Họ là các tế bào của tế bào trống/tiền thân có thể làm phát sinh nhiều mô loại như các tế bào da, tế bào cơ, tế bào thần kinh và nhiều hơn nữa... The second W, Where do Stem cell come from ?
