Research Offers Clue Into How Hearts Can Regenerate in Some Species

In my article it explains how doctors and researchers have recently found clues that might lead to ways our hearts may start regenerating. So far in medical research doctors have had little success with healing or regenerating any damaged tissue in a patients hear. We have now found that in nature hearts are able to regenerate without the use of stem cells. Humans do have the natural limited ability to slowly regenerate heart muscle cells. It is estimated that about half the cells in the human heart are replaced over a human lifetime. We have found clues from the animal the zebra fish. This unusual creature can regenerate its heart even when the bottom fifth of it has been cut off. Through experimentation on the zebra fish scientists have found a new recipe for heart regeneration. The procedure goes like this, first you have to take the mature cells and walk them back in development to a stem like state. The second step is for these stem like heart muscle cells to grow and divide, generating replacement tissue. Scientists are currently researching ways and working on how to imitate the way the zebra fish can regenerate its heart. This subject talked about in this article shows how much science is advancing and how in somewhere around 5 to 10 years it would be possible to grow back parts of our own hearts. I chose this article because I think that this subject will actually be very important to future health problems. I think one thing that this article did not do well was tell us what they were planning work on in the future. All the really talked about was getting clues from a zebra fish. But mostly this article was very well written and contained a lot of useful information.
