Induced pluripotent stem cells (iPSCs) differ from ESCs. They share many similar properties, such as pluripotency & differentiation potential, the expression of pluripotency genes, epigenetic patterns, embryoid body, & teratoma formation, & viable chimera formation, but there are many differences within these properties.

B. 错

The chromatin of Induced pluripotent stem cells (iPSCs) appears to be more "closed" or methylated than that of embryonic stem cells (ESCs).

A. 对
B. 错

Multipotent stem cells are found in amniotic fluid. These stem cells are very active, expand extensively without feeders and are not tumorigenic.

A. 对
B. 错
