A researcher isolates inner cell mass cells from a human blastocyst to obtain embryonic stem cells (ESCs). She also reprograms adult skin cells from the same patient by introducing specific transcription factors to produce induced pluripotent stem cells (iPSCs). Which statement correctly compares the differentiation potential of ESCs and iPSCs?

A researcher isolates three cell populations to investigate repair of damaged cardiac muscle:
(1) cells from a 5-day-old human embryo that can differentiate into any cell type, including extra-embryonic tissues such as the placenta;
(2) cells from the bone marrow of an adult human; and
(3) adult skin cells reprogrammed in the laboratory by introducing specific transcription factors. Which of the following correctly classifies cell populations 1, 2, and 3?
