Advantages and Disadvantages to Embryonic and Adult Stem Cells. Host rejection minimized Possibility of rejection?? Difficult to isolate in adult tissue. Easy to obtain but blastocyst is destroyed Less Stable. Capacity for self-renewal is limited. Stable. Can undergo many cell divisions. “ Multipotent” (“can become many but not any”) “ Pluripotent” (can become any cell) Adult S.C. Embryonic S.C.
