Pluripotency in the broad sense refers to "having more than one potential outcome." In biological systems, this can refer either to cells or to biological compounds. From the Latin pluri=many, potent=power, capacity. A pluripotent cell can create all cell types except for extra embryonic tissue, unlike a totipotent cell, (tot=all), which can produce every cell type including extra embryonic tissue.
