The use of embryonic stem cell differentiation produce sperm, is and cloning instead a process. The former is the almighty cells into some highly differentiated directional training with special function of cells; But cloning is highly differentiated cell reductive into the almighty primitive cells. "HanChunSheng so explained.
The development of a fertilized ovum into blastosphere, a group of cells of blastosphere center each has developed a new individual potential, known as this is, <a href="http://www.beatsbydre-canada-sale.com/"><strong>Beats By Dr.Dre</a></strong> these cells can split them in the infinite expansion, called embryonic stem cells. These cells down again in the formation of the differentiation development of the various types of cells, lost totipotency.
Use of embryonic stem cells to develop all kinds of human body tissue and organ, is the scientific research also very popular in a direction. And this obviously and cloning technology development on the stimulus. It's easy to understand that when a person of the tissues and organs appear some problems, only in his own tissues and organs is the most ideal to replace. Cloning technology, we can use a person's cells produced and he genetically identical embryonic stem cells, and then make the embryonic stem cells to specific tissues or organs, we can realize own organ replacement.
Manufacturing "artificial sperm" solve the problem of male infertility, follow the same idea. The use of embryonic stem cells produce sperm for the embryo sperm. More image some said, if the embryo is a baby boy, so get sperm and the baby boy grow up after the mature sperm is naturally produced all the same. A male infertility patients want to get their sperm, <a href="http://www.beatsbydrdre-cuffie.it/">beats by dre</a> first to show their cells through cloning technology reduction to embryonic stem cells, and then reuse the embryonic stem cells sperm, after such a reciprocating process can be satisfied.
HanChunSheng researcher, said the Japanese scientists published the results really is a big breakthrough, but still only man-made sperm research field a gradual development efforts. For example, they in laboratory nurture a successful actually just primitive germ cells, and not the real sperm cells.
We know, the human body the general cells have 23 chromosomes, such as spermatagonial cells and the cell is such eggs. And as a special cells sperm and egg, <strong><a href="http://www.monclerjackets-outlet.co.uk/">Moncler Jackets</a></strong> chromosome number only half the normal cells, namely article 23. This came to fertilize an egg, the chromosome number of the fertilized egg will return to of 23 to.
SSCS only after meiosis, chromosome number halved, to become a real sense of sperm. And in Japanese scientists this time the work, the process is not in the laboratory of artificial complete, but the spermatagonial cells implanted into the mice in the testicles, through the natural process is complete.
However, HanChunSheng also said that not long ago have another Japanese scientists just published this research results: they will mice testicular tissue of the in vitro culture in the laboratory environment to a successful meiosis, and access to the can produce offspring sperm.
The different combination of scientists research effort, <a href="http://www.monsterbeatsbydrdre-australia.com/"><strong>beats by dr dre</a></strong> maybe in the future, we may move forward further. HanChunSheng said, Chinese scientists in man-made sperm field has been his also efforts, and Japanese scientists breakthrough let them have more sense of urgency. |
