Stem (medicine)
Stem (pronounced: /stɛm/) in the field of medicine refers to the main body or stalk of a bodily organ or part, such as the stem of a brain, the stem of a plant, or the stem cells in the human body. The term originates from the Old English word 'stefn', meaning 'tree trunk', which is a metaphorical reference to the main body or stalk of an organ or part.
Stem Cells
Stem cells (pronounced: /stɛm sɛlz/) are undifferentiated or partially differentiated cells that can differentiate into various types of cells and proliferate indefinitely to produce more of the same stem cell. They are the building blocks of life and repair systems for the body.
Stem Cell Therapy
Stem cell therapy (pronounced: /stɛm sɛl θɛrəpi/) is the use of stem cells to treat or prevent a disease or condition. It's a rapidly evolving field, and the potential applications are vast, from repairing damaged tissues and organs to treating immune disorders and cancers.
