A four-cell embryo normally develops into a blastocyst consisting of trophectoderm (TE) cells on the outside and inner cell mass (ICM) cells inside. The transplantation experiments were done with mouse embryos.

A. If a labeled cell is placed on the outside of a very early embryo, it is likely to form extraembryonic tissues.

B. If a labeled cell is placed on the inside of a very early embryo, it is likely to form embryonic tissues.
