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.
Totipotent cells can form all the cell types in a body, plus the extraembryonic, or placental, cells. Embryonic cells within the first couple of cell divisions after fertilization are the only cells that are totipotent.Pluripotent cells can give rise to all of the cell types that make up the body; embryonic stem cells are considered pluripotent.Multipotent cells can develop into more than one cell type, but are more limited than pluripotent cells; adult stem cells and cord blood stem cells are considered multipotent.mbryonic cells within the first couple of cell divisions after fertilization are the only cells that are totipotent.
