Objective:
We want to differentiate mesenchymal stem cells from rat bone marrow cells to osteoblost cells.If we look more carefully at our world , we can see many patients who need help and there is no real cure for their diseases yet. But now,after many research and experiments on stem cells, there is hope to discover some new methods to cure hard diseases such as cancer, heart diseases and other injuries that still have not definite treatments and can suffer many people in our world.We think it is necessary to think and do something about that. we are eager to share our information with the students from other countries to become more interested and active in this field. We hope through this way to simplify this subject and exchange ideas with other students.
