Is the author’s argument valid or invalid, sound or unsound, strong or weak? Explain how you determined this.

When a human embryo consists of not more than 64 cells, its cells are, like a young dog, able to learn new tricks. If injected into a diseased kidney, they take on many of the properties of ordinary kidney cells, and may help the kidney to perform its normal function. This seems to hold for any organ, even any kind of cell. .
