Scientists at the UNIGE have identified the genetic sequences that regulate the activity of the genes responsible for bone growth. In mammals, only 3% of the genome consists of coding genes which ...

They are important for growth. Some people find the use of embryonic stem cells ethically ... For example, blood stem cells found in bone marrow can differentiate into red blood cells, platelets ...

The best source is the five-day-old embryo. Adult stem cells will differentiate into a narrower range of cell types. Bone marrow transplants are an example of adult stem cell transplant.
