Why stem cells are bad and good?

I think that the stem cells are good because they are very helpful inside our bodies because they can get the shape and the function that they do in our bodies. On the other hand the scientist has to cultivate sperm and ovaries, and they experiment with those two reproductive cells in a developing embryo, stem cells can differentiate into all of the specialized embryonic tissues. In adult organisms, stem cells and progenitor cells act as a repair system for the body, replenishing specialized cells, but also maintain the normal turnover of regenerative organs, such as blood, skin or intestinal tissues, they put them together and they start to produce a human being. When the little Embryo has two or three week they take out the stem cell. And they do more and more stem cell, whet h scientists take out the stem cell from the Embryo they kill that Embryo that is almost a human being. That’s why I think stem cells are good and are thank you for paying attention for how is the procedure for cultivating stem cell.
