11. Metamorphoses and injects its internal cell mass into host animal. 12. During embryonic development these inner cell mass cells continuously divide and become more specialized. 13. He extended this work to study physical properties of mammalian cell mass and stiffness. 14. On the inside, tucked inside the mostly hollow core, is a stem cell mass . 15. Embryonic stem cells of the inner cell mass are body. 16. It possesses an inner cell mass ( ICM ) which subsequently forms the embryo. 17. The epiblast layer is derived from the inner cell mass . 18. This layer surrounds the inner cell mass and a fluid-filled cavity known as the blastocoele. 19. Another tissue stress function is to regulate homologous tissue cell mass in various physiological conditions. 20. Stem cells are created by removing an inner cell mass from a 5-to 7-day-old embryo.
