From one cell to two-hundred different kinds of cells. Cell differentiation is the process of a cell changing from one cell type to another in developmental biology. In this process stem cells are used. A stem cell is a cell that has the ability to continuously divide and differentiate into various other kinds of cells or tissues. The process of differentiation results from the protein make-up of a cell. The blueprints for making these proteins are found in the nucleus of each cell as DNA; thus, the starting point of differentiation is in the nucleus which contains all the guidance to make all of the cell type collection. During cell differentiation, genes are turned on and off which determines what kind of cell it is or what it functions as.

Their potency characterizes the range to which their offspring can be of different cell types. Cells lose potency as they differentiate. Potential is having or showing the capacity to become or develop into something in the future. The original cell is totipotent; this means that the cell has the ability to potentially become any cell in the organism. These stem cells are the most powerful. Totipotent cells can even be a new individual organism; for example, they could potentially become a twin. The next level of stem cells is known as pluripotent. Pluripotent cells can develop into a variety of tissue types. Pluripotent cells can form over 200 cell types. This type of cell has less potential than totipotent cells. After, pluripotent cells comes multipotent cells. This type of cell is less potential than pluripotent cells. Multipotent cells are limited to specific categories of cells; therefore, these cells can form fetal tissue, cord blood, and adult stem cells. Lastly, are unipotent cells. Unipotent cells potentially can’t be anything else. These stem cells are very specific and can’t become anything …show more content…
Dorns Taylor used a detergent to drip out old cells from an organ leaving only a scaffold to work with. She then put in new stem cells to grow a new organ. Also, Anthony Atala used biomaterials that eventually disintegrate. Stem cells and other cells would be layered onto the biomaterial to mold the organ. Eventually the organ would be working and the biomaterials would disintegrate. This was used for smaller organs. Also, organs have been engineered using man-made materials. Anthony Atala used a printer to make an organ. This was very interesting and high tech. He also made a kidney out of wafers and kidney cells. Another man-made device was used to make a liver. Howard Pryor engineered a device to replace a liver using its good liver cells and have the device to the exact same job as the liver. People cannot live without a liver so this was very
