To obtain adult stem cells

Metrics details. Life-long tissue homeostasis of adult tissues is supposedly maintained by the resident stem cells. However, it has proved difficult to isolate these quiescent stem cells as a physical entity. Recent single-cell RNAseq studies on several adult tissues including ovary, prostate, and cardiac tissues have not been able to detect stem cells. Thus, it has been postulated that adult cells dedifferentiate to stem-like state to ensure regeneration and can be defined as cells capable to replace lost cells through mitosis.

Stem cell - Wikipedia
Cell biology is the subdiscipline of biology that studies the basic unit of life, the cell. Cell biology does not stand alone as a discipline but is closely related to other areas of biology such as genetics , molecular biology, and biochemistry. Based on one of the basic principles of biology , the cell theory , the study of cells would not have been possible without the invention of the microscope. With the advanced microscopes of today, such as the Scanning Electron Microscope and Transmission Electron Microscope, cell biologists are able to obtain detailed images of the smallest of cell structures and organelles. All living organisms are composed of cells. Some organisms are comprised of cells that number in the trillions.

Debates over the ethics of embryonic stem cell research have divided scientists, politicians, and religious groups for years. 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. Many parties continue to have strong opinions that trigger ongoing debates about stem cell research, and the following pros and cons provide a snapshot of some the points on each side of the issue. Stem cells provide huge potential for finding treatments and cures to a vast array of medical issues:.
An embryo develops from a fertilised egg. Cells in the early stages of the development of an embryo are known as stem cells. These are cells that have not undergone differentiation.
