Yes, a blastocyst contains pluripotent stem cells, which have the ability to differentiate into almost any cell type in the body. This means they can give rise to various specialized cells, not just their own type. However, once these stem cells differentiate into specific cell types, they lose the ability to become other types of cells.

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.
they are unipotent

Only adult stem cells produce progenitor cells because they multiply though the process of cell division and therefore produce progenitor cells.
yes
they can only produce cells that are like themselves
Stem cells. that is why they are needed for research
No, Because chemicals are not living things...only living things will produce cells.
