Final answer:
The exact gene used to locate differentiated cells in the overexpression of FoxO is not provided, but the Wnt signaling pathway is involved in cell differentiation during development OPTION A IS ANSWER
Step-by-step explanation:
In the context of the overexpression of FoxO, the gene used to locate differentiated cells is not explicitly mentioned in the question. However, analyzing the provided information, we can infer that it relates to the transcription pathways and developmental biology.
For instance, the Wnt signaling pathway plays a crucial role in the course of animal development by guiding the differentiation of ectodermal cells into epidermal cells and the neural plate, which would make it a likely candidate.
In terms of shared ancestry, the transcription factors expressed by Hox genes in the mouse embryo reveal a conserved strategy for cell communication and regulation of transcription factors that suggests a common evolutionary origin OPTION A IS ANSWER
