Bone substitutes
synthetic or natural materials for the replacement of bones or bone tissue. They include hard tissue replacement polymers, natural coral, hydroxyapatite, beta-tricalcium phosphate, and various other biomaterials.
Bone
The vertebrate body is supported by an endoskeleton made of cartilage and bone. (Sharks and their relatives use only cartilage.)
The bones of the human skeleton perform several functions: ...

Bone
Structure and Physical Properties."Bone is one of the hardest structures of the animal body; it possesses also a certain degree of toughness and elasticity. Its color, in a fresh state, is pinkish-white externally, and deep red within.
Bone marrow transplants. As in sickle-cell and cystic fibrosis families, chronicity presents an inevitable drain upon financial resources, concerns about insurance coverage, the effect on a potential mate, and certain problems with long-term care.
compact bone The outer dense layer that forms the shaft of the long bones; made up of concentric layers of mineral deposits surrounding a central opening. PICTURE ...
Bone, shown in Figure 8, has calcium salts in the matrix, giving it greater rigidity and strength. Bone also serves as a reservoir (or sink) for calcium. Protein fibers provide elasticity while minerals provide elasticity. Two types of bone occur.

Bone os, G. osteon = bone.
bony fishes Fishes with a skeleton made mostly of bone; they also have gill covers.
A Human Bone
In order to provide your body with the strength you need to keep your shape, to move, to hold your weight, and to protect your organs, your bones need to be very strong.
The bone marrow is a rich source of a variety of stem cells. First we have the original hematopoietic stem cell, the precursor to all blood lineages. It's been known about for a long time.
[Gr. osteon - bone; Gr. blastos - germ, bud, shoot]. A cell which produces bone matrix. An osteoblast will become an osteocyte once it becomes embedded within the matrix of the bone.
cancer of the bone marrow resulting in excess production of leukocytes.

A cell within bone marrow that is a progenitor for any kind of blood cell.
point mutation
A change in a gene at a single nucleotide pair.

For over 30 years, bone marrow (adult) stem cells have been used to treat cancer patients with conditions such as leukemia and lymphoma. During chemotherapy, most growing cells are killed by the cytotoxic agents.
And people have stem cells in their bone marrow that give rise to all the different kinds of blood that they have. There are stem cells in the liver that give rise to hepatocytes and secretory cells.
Procynosuchus shows an increase in size of the dentary bone and the beginnings of a palate. Thrinaxodon has a reduced number of incisors, a precursor to tooth differentiation.
The immune system Cells in our bone marrow, thymus, and the lymphatic system of ducts and nodes, spleen, and blood that function to protect us. Antigen Anything causing an immune response, usually foreign material but may be our own tissues.
Usually only animals with "hard parts" such as bone and shell are preserved.
Other diseases cause problems with bone formation and related connective tissues including collagen.
Cancer of the developing blood cells in the bone marrow. Leukemia leads to rampant overproduction of white blood cells (leukocytes); symptoms usually include anaemia, fever, enlarged liver, spleen, and/or lymph nodes. [Talking Glossary]

osteoblast [Gr. osteon - bone; Gr. blastos - germ, bud, shoot]. A cell which produces bone matrix. An osteoblast will become an osteocyte once it becomes embedded within the matrix of the bone.
ossification -- n. The process of bone formation. Special cells called osteoblasts secrete minerals that combine with a network of collagen fibers, forming the hard bone matrix.
A variety of white blood cells present in blood, lymph nodes, spleen, thymus gland, gut wall and bone marrow.
They have jaws, their skeleton is made up of bone and their body is covered with overlapping scales. Most familiar freshwater and sea water fishes belong to this group.
Undifferentiated, primitive cells in the bone marrow that have the ability both to multiply and to differentiate into specific blood cells.
Structural genomics ...
- A type of leukocyte found in the blood, lymph nodes and certain organs. Lymphocytes are continuously made in the bone marrow (see also B lymphocytes and T lymphocytes).
The skull cavity through which the spinal cord passes (see occipital bone) ...
head mesenchyme - mesoderm that will give rise, along with cranial neural crest cells, to connective tissue, bone and musculature in the head.
Human growth hormone (HGH, somatotrophin). A protein produced in the pituitary gland that stimulates the liver to produce somatomedins, which stimulate growth of bone and muscle.
Rickets A disease caused by the insufficient formation of vitamin D, resulting in the inadequate calcification of cartilage and bone.
