There are a lot of cells and tissues that support the developing embryo. How do you think this changes if the mother is a litter bearing animal such as cat, dog or mouse? (be sure to provide references to defend your answer

The cells and tissues support embryonic development in mammalian offsprings as these cells have the capacity to divide and differentiate.

Explanation:

Since the time from copulation till delivery of fetus several changes occur in the body of the mammalian mother including animals like cat, dog, and mouse to support the pregnancy. There are specialized totipotent cells which are proliferating specialized cells they have tendency to divide quickly and differentiate into functional types so that they can become a specialized organ or part of the body. If take an example of human which is also mammal in mother body after conception the egg gets fertilized to form sperm which changes to embryo the embryo divides and differentiate to form blastocysts and further divides and differentiate in several stages to become fetus.
