Types of products[edit] Plywood, wood structural panel, is sometimes called the original engineered wood product. Plywood is manufactured from sheets of cross-laminated veneer and bonded under heat and pressure with durable, moisture-resistant adhesives.
If the embryos have been kept in the freezer for one year or longer, parents may choose to: A second source of stem cells can be obtained from aborted fetuses, where the germ cells (ovaries and testes) are of particular interest. A third source of stem cells, known as multipotent stem cells, can be found in many types of adult tissue such as bone marrow, adipose tissue (fat), and umbilical cord blood. Adult stem cells are needed every day to replenish a variety of cell types in our body that normally wear out and die in large numbers.
Multipotent stem cells can also differentiate into myeloid progenitor cells, which can differentiate into neutrophils and macrophages (as well as red blood cells and platelets). B lymphocytes (produced and matured in the bone marrow) can bind to non self antigens (foreign proteins in the body) on the surface of a bacterium via specific antigen receptors.
