Physician examining a patient.
Esclapius stick coloured.svg
Medicine is the branch of health science and the sector of public life concerned with maintaining or restoring human health through the study, diagnosis and treatment of disease and injury. It is both an area of knowledge — a science of body systems, their diseases and treatment — and the applied practice — an art or craft — of that knowledge. However, medicine often refers more specifically to matters dealt with by physicians and surgeons.

The term "medicine" is sometimes used amongst medical professionals as shorthand for internal medicine. Veterinary medicine is the practice of health care in animal species other than human beings. Please see our medical disclaimer for cautions about Wikipedia's limitations.

Stem cells in humans are primal undifferentiated cells that retain the ability to produce an identical copy of themselves when they divide (clone) and differentiate into other cell types. In higher animals this function is the defining property of the deleted cells. Stem cells have the ability to act as a repair system for the body, because they can divide and differentiate, replenishing other cells as long as the host organism is alive.

Medical researchers believe stem cell research has the potential to change the face of human disease by being used to repair specific tissues or to grow organs. Yet there is general agreement that, "significant technical hurdles remain that will only be overcome through years of intensive research.". Current evidence indicates that some stem cells are involved in assisting cancer's proliferation, or worse yet, some stem cells act as cancer stem cells (CSC). (More...)

Did you know...?

  • ...that during the "Age of Heroic Medicine" (1780-1850), educated professional physicians aggressively practiced "heroic medicine", including bloodletting (venesection), intestinal purging (calomel), vomiting (tartar emetic), profuse sweating (diaphoretics) and blistering? These medical treatments were well-intentioned, and often well-accepted by the medical community, but were actually harmful to the patient.
