Developmental biologists study stem cells and their function. Of particular interest is the way that stem cells are able to renew and clone themselves. Stem cells are able to self-renew at the same time that they work to create new organs. Stem cells also produce clones, or copies, that are genetically identical. Within developmental biology, the study of stem cells plays an important role in finding cures for various diseases and degenerative disorders.
Another topic within developmental biology is the study of cell communication. DNA provides the genetic code for all life forms; however, in order for life to develop, there must be communication between the cells to create an organism. Developmental biologists attempt to better understand the pathways through which these cells communicate. Cell communication is important, not only for understanding how life forms, but also for understanding the formation of diseases.
Form form uniformity refers to the way uniform structures are able to produce three-dimensional life structures, such as organs. Developmental biologists attempt to understand the production of organs, tissues, and systems of the body as well as their complexities. Examples of form form uniformity include the formation of hair cells from epithelial cells, the way an embryo forms from an egg, as well as the way bacteria and yeast mature and develop.
The field of developmental biology is broad and encompasses many topics. Other topics include the study of the human body and the development of cells and organs, such as the brain and nervous system. Developmental biologists study the development of diseases, hormones, as well as the formation of the sexes and the death of cells. They examine the differences between vertebrates, such as humans, and invertebrates, such as plants and their development. Understanding the differences in development of these living organisms allows scientists to better understand and isolate genes.
