Explain how cells specialize to form specific tissue and organs.

One second I will help.  I just need to figure it out first

anonymous · Answer

All cells have the same DNA. They are different because different genes have been locked up and only some of them are expressed. The process began in the embryonic stage, when stem cells are turned into different types of cells by turning off some of the genes. Scientists have been looking for ways to reverse the process, meaning turning specialized cells back into stem cells. Some success has been reported using different methods. The latest one uses a weak acid to stress the cells. https://answers.yahoo.com/question/index?qid=20140304102535AAbLz9Y

thank you!!

I think ips( not sure if that is exact) they hit cells with for chemical signals to make them into stem cells.

Before cells are specialised, they are called stem cells which are unspecialised cells. These stem cells can be found in human embryos or in bone marrow. 
There are totipotent, pluripotent and multipotent stem cells. 
Basically, scientists can genetically modify these stem cells to make organs and tissue for example brain cells or liver tissue and use them to cure diseases and help people 


Also cell specialisation occurs during the development of a young cell when a specific gene causes it to build up different features for a particular function
