The embryonic stem cells and what they can do

Much ethical controversies and discussion was being brought about by embryonic stem cells. The embryonic stem cells came from embryos which among all the stem cells have the ability to self-renew for a long period of time.
Moreover, they also have the ability to differentiate into specialized cells with their own functions. A proof of this is their ability to differentiate into all derivatives of the main germ layers, including over 220 types of cells in the human adult body.
Stem cell research pros and cons
Vitro fertilization is where the embroyonic stem cells where usually derived. Egss were fertilized into this vitro then donated for reasearch with the donor's consent. After four or five days old, when the embryo already have a tiny ball of cells known as blastocyst, the embroyos are being utilized.

Embryonic stem cells can be totipotent or pluripotent. Pluripotent embryonic stem cells which can become any type of cell in the body except from those that are needed to develop fetus are derived from the blastocyst. Totipotent embryonic stem cells on the other hand which includes the fertilized egg and the cells produced during the early divisions have the ability to become any other cell in the body.

The development of an embryonic stem cells, their benefits, and issues.

Diseases like diabetes, cardiovascular disease, cancer, parkinson's disease and spinal injuries can be treated by transplanting cells that were harvested from the human embryo. This will only be possible if the scientist were able to follow the differentiation of embryonic stem cells into different cell types where they can replace the diseased and dysfunctional cells.

Embryonic stem cells are very useful for cell-based therapies. They came from early blastocysts, an early stage where they can develop into one of more than 220 cell types of an adult. As scientist continue to research new techniques, they will be able to cure vast number of diseases. And the ability of embryonic stem cells to proliferate indefinitely can mean a mass production to replace the damaged cells in a diseased adult's body.
Moreover, safety on drugs can also be improved by testing the them on embryonic stem cell lines before testing them to laboratory animals and human. In addition, if researchers know how these cells develop, they can better understand how and what happened to the cells which lead to diseases like cancer and other birth defects.

However, after the embryonic stem cells' ability to treat disease because they can self-renew, ethical controversies like destruction of an embryo for cells and immune rejection where a patient's immune system may not accept the healthy embryonic stem cells are just few of the concerns that surrounds this issue.

Though the discovery embryonic stem cells can really be beneficial, their use will most likely be inconsistent and may not be approved until the process of growing and isolating them are known. Refusal from the public can also be a problem when it comes to using this embryonic stem cells. But if these problems can be overcome in the future, suffering from serious diseases can be lessen because of this embryonic stem cells.
