Embryonic Stem Cells and Disease Part 1 of 6

Brought to you by the Howard Hughes Medical Institute, this lecture by Dr. Douglas A. Melton is part of a series of lectures devoted to a discussion about the nature of embryonic stem cells and their potential use in the treatment of human disease. Understanding the mechanisms by which particular cell types are generated are of primary concern to be able to fully harness the medicinal potential of embryonic stem cells.

HHMI description:
There are two main approaches to using stem cells to fight human diseases: develop stem cells to produce therapeutic replacement cells and study stem cells as a model for understanding the biology of a disease. Significant progress has been made in producing stem cell lines that, for example, participate in the regeneration of damaged nervous tissue. Many human diseases, such as juvenile diabetes (type 1 diabetes), involve malfunctioning genes and environmental triggers. Usually, a specific type of cell is primarily affected by the disease, and the cellular dysfunction produces the symptoms. In juvenile diabetes, the insulin-producing islet cells of the pancreas are destroyed. Insulin is critical to the proper regulation of sugar by the body, and its absence causes the severe condition called diabetes. Researchers want to coax embryonic stem cells into becoming healthy insulin-producing cells. These cells might then be transplanted into people with diabetes to produce the insulin they lack. Researchers are also interested in producing stem cells that malfunction exactly like the diseased cells in order to understand fundamental aspects of the disease and also to test treatments.

@hlkolaya yes useing radiation can put a person at cancer risk. it is based on something as small at atoms. in the nucleaus we have protons and neutrons. and is even on proton is changed say it was oxygen with 8 protons then it will be changed to become Nitrogen with 7 protons. it is very defective. that is how we get skin cancer from the sun radiation.

can i get feed back on whether you understtod what i said? please PLEASE

LOL ROFL :D

did you se that kid touching his pimples??

[hlkolaya]

could there be long term effects from destroying the cell nucleus using radiation? would it possibly increase the chances for cancer or other deformities?
