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.
blastocyst The most versatile stem cells occur earliest in life. As a fertilized human egg divides, it first becomes a solid ball of cells, the morula. Next, about five days after fertilization, it becomes a hollow ball, the blastocyst. The cells of the outer layer of the blastocyst eventually form part of the placenta.
In order to obtain stem cells, an embryo must be in the blastocyst stage.
Cells up to 8 cell stage in human embryo can develop in any kind of cell in body. Inner cell mass in blastocyst can develop into any kind of cell in human body.
A stem cell is a cell that has the ability to generate itself into any body part or cell type of the organism it is developing. Stem cells are found in the blastocyst of an embryo and ALSO in adults. Because adults have already finished developing, the stems cells are then used to maintain regenerative organs such as skin, blood or intestinal tissues. All other adult cells do not have the ability to regenerate.
Embryonic stem cells (ES cells) are stem cells derived from the inner cell mass of the blastocyst, an early-stage embryo.In other words, they do not become embryos, they are part of an embryo.

Two different answers: Myeloid stem cell. The other cell types are more differentiated. or Lymphocyte because it develops from from a lymphoid progenitor cell. The rest develop from a myeloid stem cell.
Cells up to 8 cell stage in human embryo can develop in any kind of cell in body. Inner cell mass in blastocyst can develop into any kind of cell in human body.

Amniotic stem cell bank a facility that stores stem cell derived from amniotic fluid for future use. the first private amniotic stem cell bank in the US was opened by Biocell center in October 2009 in Medford, Massachusetts.
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).
