Medical Technology

The development of technology today is definitely AMAZING!!!!! especially in medical tech, One of thousand from those is this STEM CELL Research conduct by all those brilliant biology scientists and others too . . . look at benefit for cancer curement process and the desease seed that already in our blood since we're born.
I got this from http://en.wikipedia.org/wiki/Stem_cell, try and read some . . .

Stem cells are cells found in most, if not all, multi-cellular organisms. They are characterized by the ability to renew themselves through mitotic cell division and differentiating into a diverse range of specialized cell types. Research in the stem cell field grew out of findings by Canadian scientists Ernest A. McCulloch and James E. Till in the 1960s.^[1][2] The two broad types of mammalian stem cells are: embryonic stem cells that are isolated from the inner cell mass of blastocysts, and adult stem cells that are found in adult tissues. In a developing embryo, stem cells can differentiate into all of the specialized embryonic tissues. In adult organisms, stem cells and progenitor cells act as a repair system for the body, replenishing specialized cells, but also maintain the normal turnover of regenerative organs, such as blood, skin or intestinal tissues.

Stem cells can now be grown and transformed into specialized cells with characteristics consistent with cells of various tissues such as muscles or nerves through cell culture. Highly plastic adult stem cells from a variety of sources, including umbilical cord blood and bone marrow, are routinely used in medical therapies. Embryonic cell lines and autologous embryonic stem cells generated through therapeutic cloning have also been proposed as promising candidates for future therapies. ^[3]

and this one too, it's from www.brown.edu/Courses/BI0032/adltstem/asc.htm about adult stem cell . . . . The major function of adult stem cells is to maintain homeostasis in the body in terms of replacing dead or injured cells with new ones that function correctly. At this point in time, no one truly knows the origin of adult stem cells in mature tissue. It is said that adult stem cells are clonogenic and unilineal. Clonogenic means that the cells generate identical copies of themselves, then diffirentiate into mature cells of the tissue in which it resides. Unilineal means that a cell differentiates into a specific, more mature cell, using one or more intermediate steps. To say that adult stem cells are unilineal would be to say that there is no such thing as a pluri, or multipotent stem cell in adults. (4) . . . . .

So when we're talking about stem cell, we're goin' to talk about regeneration of our broken cell . . . i don't know whether if it's rapid regeneration or not . . . ask the researcher of course ^_^ but all i can presume is that in the far future there will be no desease with no cure . . . hope i am still alive to watch those precious moment.
