STEM CELL THERAPY

TOPIC: Science & Tech

Context- A U.S. patient with leukemia has become the first woman and the third person to date to be cured of HIV after receiving a stem cell transplant from a donor who was naturally resistant to the virus that causes AIDS.

Concept-

Stem Cell Therapy:

  • Stem-cell therapy is the use of stem cells to treat or prevent a disease or condition.
  • Stem cell therapy, also known as regenerative medicine, promotes the repair response of diseased, dysfunctional or injured tissue using stem cells or their derivatives.
  • Stem cells can then be implanted into a person.

Stem Cells:

  • Stem cells are the cells from which all other cells with specialized functions are generated.
  • Under certain conditions in the body or a laboratory, stem cells divide to form more cells called daughter cells.
  • These daughter cells either become new stem cells (self-renewal) or become specialized cells (differentiation) with a more specific function, such as blood cells, brain cells, heart muscle cells or bone cells.
  • No other cell in the body has the natural ability to generate new cell types.

HIV:

  • HIV is a ribonucleic acid virus.
  • HIV attacks CD4, a type of White Blood Cell (T cells) in the body’s immune system. T cells are those cells that move around the body detecting anomalies and infections in cells.
  • HIV is transmitted from person to person through bodily fluids including blood, semen, vaginal secretions, anal fluids and breast milk.
