Witryna25 maj 2024 · It is distinct from a blastocyst in that a morula (3–4 days after fertilization) is a mass of totipotent cells in a spherical shape whereas a blastocyst (4–5 days after fertilization) has a cavity inside the zona pellucida along with an inner cell mass. A morula, if untouched and allowed to grow, will eventually develop into a blastocyst. WitrynaAre inner mass cells totipotent? Pluripotent, embryonic stem cells originate as inner mass cells within a blastocyst. These stem cells can become any tissue in the body, excluding a placenta. Only the morula’s cells are totipotent, able to become all tissues and a placenta.

WitrynaThe inner cell mass (ICM) forms within the blastocyst, prior to its implantation within the uterus.
