In addition, specific proteins or biological substances can be added to these stem cell cultures to transform them in the laboratory into a large variety of specialized cell types, such as nerve, liver, muscle, bone, and blood cells. (jcpa.org)
Hayashi and his team previously found a way to take skin cells from a female mouse and transform them into an egg that could be used to give birth to healthy pups. (iol.co.za)
However, it appears that the ability of the In its simplest form, cloning is defined stem cells to transform is limited, except as the exact replication of cells. (who.int)
