totipotency is the ability of stem cells to differentiate into all the 216 different cell types in the body. In the blastocyst stage the outer layer of cells form the placenta, but the inner layer of cells forms the embryo but it doesnt have the ability to differentiate into cell types such as the placenta. These cells are called pluripotent stem cells.
What kind(s) of cells can develop from multipotent stem cells?A. Only cells that are closely related to the original stem cell B. Only cells that are identical to the original stem cell C. Any cells of the human body or the placenta D. Any cells of the human body. but not cells of the placenta
The first concern is the destruction of human embryos to extract stem cells. Pro-life activists argue that embryos are a form of life and should be allowed to live. Another argument is that stem cell research can devalue human life as it can lead to consent of reproductive cloning.
The stem cell "culture" is the medium in which the stem cell is able to divide and grow.

Yes, it is possible to extract tissue-specific stem cells post mortem.

Hematopoietic stem cells
You can't.
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.
A stem cell can become any other type of specialized cell.
