Question

Embryonic stem cells give rise to all cell types in the developing embryo. Would you expect the interphase period of stem cells to be long or short?

Answer 1

I would expect the interphase period of stem cells to be short since embryonic stem cells undergo very rapid changes; thus interphase in them is short.

Embryonic stem cells (ES cells) are pluripotent stem cells derived from the inner cell mass of a blastocyst, an early-stage pre implantation embryo. Human embryos reach the blastocyst stage 4–5 days post fertilization, at which time they consist of 50–150 cells.

I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

Answer 2

The interphase period of stem cells would be short. This is because embryonic stem cells undergo rapid changes, so the interphase period would not be very long. If the entire cycle occurs during a short time period, then the interphase period is also short.
