Commercializing the stem cell sciences pot

... hES cells are considered by many to be the most fundamental and extraordinary of the stem cells; unlike the more differentiated adult stem cells or other cell types, they are pluripotent. (See the glossary ... or brain cells). Other stem cells are less committed and retain the potential to differentiate into many types of cells. It is believed that stem cells also form res...
