Stem Cells Research Paper-78
There is endless potential for scientists to learn about human growth and cell development from studying stem cells.For example, by studying how stem cells develop into specific types of cells, scientists potentially could learn how to treat or prevent relevant ailments.When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.

Studying embryonic stem cells possibly could lead to a better understanding of how embryos develop and maybe even lead to treatments that can identify and address potential problems.

Stem cell research presents problems like any form of research, but most opposition to stem cell research is philosophical and theological, focusing on questions of whether we should be taking science this far: It's not easy to obtain stem cells.

Scientists discovered ways to derive embryonic stem cells from early mouse embryos more than 30 years ago, in 1981.

The detailed study of the biology of mouse stem cells led to the discovery, in 1998, of a method to derive stem cells from human embryos and grow the cells in the laboratory. The embryos used in these studies were created for reproductive purposes through fertilization procedures.

A similar theological problem is an idea of creating living tissue in a laboratory and whether that represents humans taking on the role of God.

This argument also applies to the potential for human cloning.One of the areas of potential is embryonic treatment.This stage of pregnancy is when many birth defects or other potential issues begin.However, promising developments in other areas of stem cell research have led to solutions that help bypass these ethical barriers and win more support from those against embryonic stem cell research; the newer methods don't require the destruction of blastocysts.The excitement about stem cell research is primarily due to the medical benefits in areas of regenerative medicine and therapeutic cloning.Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth.In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive.Debates over the ethics of studying embryonic stem cells continued for nearly a decade until the use of adult-derived stem cells—known as induced pluripotent stem cells (IPSCs)—became more prevalent and alleviated those concerns.Use of adult-derived stem cells—known as induced pluripotent stem cells (IPSCs)—from blood, cord blood, skin, and other tissues have been demonstrated as effective in treating different diseases in animal models.Umbilical cord-derived stem cells obtained from the cord blood also have been isolated and used for various experimental treatments. Although these cell lines are shorter-lived than embryonic cell lines, uniparental stem cells hold vast potential if enough research money can be directed that way: pro-life advocates do not technically consider them individual living beings.Two recent developments from stem cell research involve the heart and the blood it pumps.
