Adult Stem Cells and Regeneration Part 4 of 6

This lecture by Dr. Nadia Rosenthal discusses the importance of adult stem cells in the tissue maintenance, development and regeneration. Part 4 of 6.

HHMI description:
Mature organisms have stem cells of various sorts, called adult stem cells. Adult stem cells supply cells that compensate for the loss of cells from normal cell death and turnover, such as the ever-dying cells of our skin, our blood, and the lining of our gut. They are also an essential source of cells for healing and regeneration in response to injury. Some animals, such as sea stars, newts, and flatworms, are capable of dramatic feats of regeneration, producing replacement limbs, eyes, or most of a body. It is an evolutionary puzzle why mammals have more limited powers of regeneration.

Researchers are interested in pinpointing where adult stem cells reside and in understanding how flexible adult stem cells are in their ability to produce divergent cells such as muscle and red blood cells. Understanding the sources and the rules for the differentiation of adult stem cells is essential for tapping their therapeutic potential. Since consenting adults can provide adult stem cells, some people think that adult stem cells may be a less controversial area of research than embryonic stem cells.

“I feel I am completely cured” says Ms. Gianopoulos, “my symptoms have disappeared and I have a recovery of many functions, notably my balance and my muscle strength is all coming (back). Even after six months, I feel like there are good changes happening almost every day. Before, my biggest fear was that the changes wouldn’t (hold). I don’t even worry about having a relapse anymore”.

Autologous stem cell transplantation is a procedure by which blood-forming stem cells are removed, and later injected back into the patient. All stem cells are taken from the patient themselves and cultured for later injection. In the case of a bone marrow transplant, the HSC are typically removed from the Pelvis through a large needle that can reach into the bone. Log on to ccsviclinic. ca for more information.

thumbs up video

well it is a good thing from other side... imagine the new kinds of tortures if someone cuts of your hand over and over again...

why we can't watch 2/6

[Oxygaunt]

yeah. damn those zealot assholes.. :/

[lemonheartfly]

thanks to religion we dont have the full benefit of stem cells!

[ameeek]

Cellmedicine has placed some really neat videos about stem cells here on youtube.  Just type "Cellmedicine" into search and you will see.
