Undifferentiated mesenchymal cell
The main difference between a stem cell and a differentiated cell is: A stem cell has the ability to self-renewel and also has the ability to differentiate(to become a tissue specific cell). But, a differentiated cell don't have the ability to self-renewel(moreover a stem cell get specialised to a differentiated cell).
Stem cells divide through mitosis making two cells known as daughter cells. One daughter cell becomes a stem cell and the other cell differentiates into, or turns into, the tissue the stem cell is meant to maintain.
Within the human body, stem cell niches maintain adult stem cells in a quiescent (inactive) state.
One major difference between adult and embryonic stem cells is their different abilities in the number and type of differentiated cell types they can become. Embryonic stem cell can become all cell types of the body because they are pluripotent. Adult stem cells are thought to be limited to differentiating into different cell types of their tissue of origin.
Vessicles are rather primitive and present all-throughout.

stem cell are master cell. IE. they are further differentiated into different type of cell. Their fate is to form different type of blood cells and immune system cells stem cells are undifferentiated cells that can change into the cells where they are needed. loads of cells die everyday and stem cells are used to replace them. there is now a treatment for all kinds of diseases where the body is to damaged to replace the cells. so a laboratory grows the stem cells and it is injected.
Eukaryote because it is differentiated from mesenchymal stem cells and therefore has a defined nucleus.

Because cells of the blastocyst or inner cell mass (ICM) are subjected to strong selection for proliferation, as per "survival of the fittest" phenomena of evolution (speedheart8).
Embryonic stem cells are totipotent, meaning they have the potential to become any type of body cell because the genome hasn't been differentiated yet; however, to obtain embryonic stem cells the fetus must die.
Vessicles are rather primitive and present all-throughout.
Only totipotent and pluripotent stem cells. Totipotent can become any cell type, because they come from a 3-day-embryo. Pluripotent are already differentiated cells, coming from the inner cell mass of a blastocyst kai can become any tissue cell type or any organ. Pluripotent can be extracted from the inner cell mass of the blastocyst the 5th day after the fertilization. This has ethical drawbacks. That's why the scientists are trying to extract stem cells from only one cell from the inner cell mass of the blastocyst.
stem cells are undifferentiated cells that can differentiate in to all cell types. they are of two types: 1) Embryonic stem cells ( totipotent cells) they can differentiate in to any type of cells in our body.. 2) adult stem cells ( multipotent cells) they can be differentiated into only one type of cell from which it is derived from. They are used mostly in organ and tissue transplantation. mostly used in medicinal field to cure diseases now adays.
