Grupe [1] discriminated between compact and trabecular bone tissues and reported average trace element concentrations of Mg, P, Ca, Zn, Sr and Ba in the two types of tissue.

Compact bone contains a central canal that runs the length of the bone, often called a Haversian canal. Haversian canals allow blood vessels and some nerves to reach into the bone.

Bones are composed of two types of tissue. Compact (cortical) bone is a hard outer layer that is dense, strong, and durable. It makes up around 80% of adult bone mass and forms the outer layer of ...

Engineering bone tissue from human embryonic stem cells. Proceedings of the National Academy of Sciences, May 14, 2012 DOI: 10.1073/pnas.1201830109 ...

Historically, bone’s functions in protecting vital organs and holding people up were well-known, and its relationships to things like the muscles—to which bone connects—were also recognized.

A bone autograft involves repairing bone with material from a person’s own body. Surgeons can take tissue from a person’s cancellous (spongy) bone, cortical (compact) bone, or bone marrow.

As people live longer, repairing or regenerating human tissues has become an ever-more critical issue. Just in the past decade alone, human stem cells are emerging as powerful tools for tissue ...
