Stem Cell Technologies

Technological advances in this day and age have given

scientists the ability to do things that were only dreamed about

in the past. With all the advances in medical technology there

are still diseases, illnesses and conditions that cannot be

treated or cured effectively. New discoveries and complications

commonly come about in today's world. Scientists are studying

human embryonic stem cells, which includes: how an organism

develops from a single cell and how healthy cells replace damaged

cells in adult organisms. The study of stem cells is also

leading scientists to discoveries in regenerative or reparative

medicine. This research of stem cells and their possible ability

to treat certain diseases has quickly grown popular ever since an

important discovery in 1998. Scientists discovered how to

isolate stem cells from human embryos and grow the cells in the

laboratory. In this new area of Science, questions arise as

rapidly as new discoveries are made.

Over 20 years ago, scientists discovered ways to obtain stem

cells from a mouse embryo. With only 20 years of research,

there's a lot still yet to discover about stem cells and how they

can help us. There are two characteristics that separate stem

cells from other cells. Stem cells are unspecialized cells, and

they can be induced to become cells with special functions.

Embryonic stem cells and adult stem cells are the two commonly

used by scientists. It is believed that someday in the future,

stem cells will provide the basis for treating serious diseases.

Parkinson's disease, cystic fibrosis, diabetes, paralysis,

Alzheimer's disease, spinal cord injury, heart disease, etc.,

could all be cured one day if the controversies don't delay the

research. The possibilities, depending on what scientists

discover, could change the world and science forever.

Embryonic stem cells are found in...
