Stem cell research is the advanced knowledge of cell development in a human or animal body. It is also the study of how a healthy cell can replace a damaged or dead cell in the body. This part is studied to bring out certain cell based therapies to fight against diseases as scientists believe these stem cells could be used as the basis for treatment of diseases such as diabetes and cardiac malfunctions. As of today in biology, stem cells are the most prominent area of study and research.
Stem cells exist as non specialist cells which renew there self for a period of time during cell division and under certain scenarios can be induced to become cells with special functions. Often these special cells have formed interesting tissues like heart beating muscle or the insulin production in the pancreas.
Every living organism develops tissues with the help of a blastocyst (an old embryo) and every such development brings in different types of cells which further develop to form body organs like lungs, skin, heart and other parts like muscle, brain and bone marrow.
Brain and muscle stem cells have been discovered with replacement cells which would regenerate lost cells (via injury or disease) automatically to fill the void. Stem cell research and results are extremely promising for the up coming future and still needs more extensive research to bring the best benefits in hope to help fight against life threatening diseases.
