6. Using examples from human tissues, distingui:fmlgie3wa43x 0xl7a sh between pluripotent 7bwonj.3t suukp/00ul1k i r6, totipotent and multipotent 00 t.pwusrkb 7n1 63i o/jlukustem cells.

参考答案:

Totipotent stem cells can differentiate and produce all cell types in an organism including all

types of placental tissue.

Example – (apical) meristem, zygote/early embryonic stem cells/blastula.

Pluripotent cells can produce all cell types except some embryonic tissues/(foetal) placental tissue.

Example – later embryonic tissue/morula cells/induced stem cells.

Multipotent cells can give rise to a limited number of specialised types of cell.

Example – stem cell niches/example such as bone marrow/skin stem cells.
