Molecular Biology
In the twentieth century, the mechanisms governing the specification and transmission of genetic traits were understood for the first time. Living beings are composed of cells, which in turn are composed of many types of chemicals. We are particularly concerned with large ‘macromolecules’ that enable cellular function and propagation. Given that there is specialization among classes of macromolecules, it is necessary to consider how information is conveyed between these classes. Thus the central issues of molecular biology are to identify the macromolecules that carry information, and to determine how that information is used to make other necessary macromolecules.

Adipose tissue contains a large portion of stem cells that are primarily derived from the stromal cell fraction or from the dedifferentiation of mature (lipid-filled) adipocytes. Stem cells that may give rise to adipocytes are also derived from skeletal muscle, bone and a variety of other tissues. Knowledge of these cells may prove beneficial in cell-based therapies for tissue repair, regeneration, or engineering.
