The term "organizer" refers to a group of cells that secrete signaling molecules that induce neighboring cells to adopt a specific fate during embryonic development. The very first cells would need to receive their fate instructions from an organizer in order for subsequent cell specification to occur. Mosaic specification refers to the differentiation of cells based on their position in the embryo, but does not account for how the first cell received its fate instructions. Mitotic lineage simply refers to the series of cell divisions that give rise to differentiated cells, and conditional specification refers to cells adopting a particular fate based on environmental cues rather than signaling from neighboring cells.
