Bone marrow
* All bone marrow is red.
* begins to make blood cells.
* boosts transplant success.
* can be totally normal including physiologic lymphoid hyperplasia.
* consists of at least two types of stem cells.
* contains immature cells, called stem cells
  - mesenchymal and hematopoietic stem cells
  - special cells called 'stem cells'
  - stem cells, generic cells that can form any type of blood cells
  - the hematopoietic stem cells from which all the types of blood cells are made
* factory that produce blood.
* fills the cavity inside the bone
  - marrow cavity or smaller marrow spaces, depending on the type of bone
  - spaces of the pores
* has a very special type of blood cell called a stem cell.
* is actually an organ comprised of different tissue components
  - collected by a process called harvesting
  - considered part of the immune system because it a. filters pathogens from blood
  - critical to the body's immune system because it is the source of all blood cells
  - difficult to match between donor and recipient
  - donated by live, compatible donors
  - especially sensitive to methotrexate toxicity and is the prime target for rescue
  - found in the cavities of the body's bones
* is found inside the body's large bones
  - bones, particularly the pelvic bones
  - pores of bone
  - gray and homogenous with well-defined, smooth borders
* is harvested from the pelvis
  - in a one-hour hospital procedure using anesthesia
* is important because it's the factory that makes most of our blood cells
  - obtained from multiple aspirations of the donor's iliac crests
  - part of bones
  - removed by suction and collected into a sterile syringe
* is responsible for producing most of our blood cells
  - the formation of blood cells
  - rich in stem cells
  - soft, gelatinous tissue that fills the medullary cavities - the centers of bones
  - supposed to turn out blood cells
  - taken from the hip bone
  - tested through a simple blood test
* is the 'orchard' within the bones where blood cells form
  - factory that produces cells
  - flexible tissue in the interior of bones
  - major manufacturing area of immune cells
  - material inside the bones that makes blood cells
* is the soft, fatty tissue inside bones
  - sponge-like material found inside bones
  - spongy tissue found inside bones
  - the white blood cells of the immune system
* is the spongy meshwork material that fills the cavities of large bones
  - substance found inside bones
  - tissue found in the cavities of the body s bones
* is the spongy tissue found inside large bones
  - inside the large bones in the body
  - that is located inside the long bones
  - spongy, red tissue in the centre of bones
* is the tissue inside bones that makes red blood cells, white blood cells, and platelets
  - where blood cells are manufactured
  - the bones where blood cells are made
  - tissue within the cavities of bones that contains fat cells and blood-forming cells
* is where blood cells are produced
  - stem cells live
* makes and stores blood cells
* produces immune cells
  - system cells
  - red blood cells, white blood cells and platelets
  - the body's essential white blood cells, red blood cells and platelets
* replenishes itself fully within two weeks.
* retains the ability to generate stem cells throughout life.
* shows a selective erythroid hypoplasia
  - no evidence of fracture, infection, or neoplasm
* soft, fatty tissue found inside bones.
* spongy material where blood cells are made inside bones
  - substance found in the center of the bones
* substance found in the body's hollow bones such as legs, arms, and hips
  - hollow bones of the hips, legs and arms
  - that manufactures blood components
* thick jelly that makes blood cells.
* tissue located in the cavities of large bones.
* type of tissue in the middle of certain bones that makes red blood cells.
