Description

Embryonic stem cells hold promise in health and medicine because they can transform into any cell in the human body and repair and regenerate tissues damaged by various diseases. It can also be used to screen drug candidates for toxicity. However, the generation of stem cell lines for research requires the destruction of embryos. Although it is illegal to create embryos specifically for research, U.S. researchers can use IVF embryos that would otherwise be discarded and donated to research. Under the right conditions, stem cells divide and produce more cells called daughter cells. These daughter cells give rise to either new stem cells or specialized cells (differentiation) with more specific functions, such as blood cells, brain cells, heart muscle cells, and bone cells. No other cell in the body has the natural ability to create new cell types. In normal embryonic development, they disappear after 7 days and begin to form the three layers of embryonic tissue. However, ESCs extracted from the inner cell mass at the blastocyst stage can be cultured in the laboratory and will proliferate indefinitely under appropriate conditions. ESCs growing in this undifferentiated state retain the potential to differentiate into cells of all three embryonic tissue layers. Studies using human ESCs are at the center of ethical debates regarding the use and potential of stem cells in regenerative medicine. This will destroy embryos from which ESCs have been removed.

Embryonic stem cells are cells that originate from the early stages of the embryo and can differentiate into any type of cell in the body. As the embryo grows and divides, the generalized cells must become increasingly specific as they divide. This ultimately creates the various organs, tissues, and systems of the organism. Embryonic stem cells are totipotent, i.e., they can divide into any other cell type in the animal's body. This is a process known as cell differentiation.

Embryonic stem cells can change into any type of cell in the body. Under favorable conditions, embryonic stem cells can divide into specialized cell types with specific functions, such as cardiomyocytes, brain cells, blood cells, and bone cells. These stem cells are derived from embryos at 3-5 days of age. An embryo at this stage is called a blastocyst and has about 150 cells. These are pluripotent stem cells, which mean they can divide into more stem cells or become any type of cell in the body. This versatility allows embryonic stem cells to be used to regenerate diseased tissues and organs or can be repaired.

The use of embryonic stem cells is a very new form of medicine. The causes of many degenerative diseases and physical injuries have been known for decades. Tissue damage is the underlying cause of many of these diseases, and scientists have long sought ways to grow tissues that are not easily repaired. Embryonic stem cells are pluripotent because they can become almost any cell in the body, these cells have long been studied for their potential use in medicine. From a medical point of view, the current uses of embryonic stem cells are limited, but many new uses are underway. Current treatments focus on replacing tissue damaged by injury or disease. The first of these FDA-approved treatments to be studied was for replacing damaged tissue in spinal cord injuries. There was once a concern that embryonic stem cells were collected without consent from unsuspecting women, but they are now mostly ethically collected at IVF clinics. Therefore, many eggs must be fertilized. Only one will be transplanted to women, and with the woman's consent, the rest can be used to harvest embryonic stem cells. To do this, scientists take some embryonic stem cells from the embryo, when the embryo is a small clump of cells.
