WebHuman stem cells can, however, form many of the cell types in the human brain and may offer a solution. Recently, researchers succeeded in generating organized brain tissue they called cerebral organoids from human-induced pluripotent stem cells (Figure B10.3.1).In these in vitro cultured cerebral organoids, different regions of the brain, such as cerebral … WebTotipotent cells can form all the cell types in a body, plus the extraembryonic, or placental, cells. Embryonic cells within the first couple of cell divisions after fertilization are the only cells that are totipotent. Pluripotent cells can give rise to all of the cell types that make up the body; embryonic stem cells are considered pluripotent.

WebStem cells are one of the major discoveries of modern science. They have the ability to become any other type of cell and could be used to repair damaged organs or in the treatment of disease. This GCSE Biology quiz looks more closely at stem cells and how we can use them. It also asks some ethical questions about their use. WebEmbryonic stem cells can differentiate into a wider range of cell types, but are difficult to obtain. The best source is a five-day-old embryo, although there are clinical, ethical and... how old is that lay lay
