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).
Stroma cells are usually the cells which supply nutrition to the parenchymial (core) cells to stay alive and grow, in form of vessles.
Stem cells can replicate indefinetely whereas progenitor cells can replicate only a specific number of times
Stem cells are capable of self-renewal and assymetrical division to give rise to progenitor cells. Progenitor cells are cells that can further differentiate into other cells though it has lost the stem cell's ability to self-renew. When a stem cell divides, the same stem cell and a progenitor cell is produced. The production of the same stem cell is evidence of self-renewal and the production of a cell different from the parent cell is evidence of assymetrical division (regular mitosis gives rise to two identical daughter cells).
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.
There are four types of stem cells widely used today. They are Embryonic stem Cells - from a Embryo or fetus. There is also, Hematopoietic stem cells what are adult bone marrow. There is Neuronal stem cells what are from the brain. Finally there is another type of bone marrow what is called Mesenchymal stem cells. The difference between Mesenchymal and Hematopictic stem cells is because of there Daughter tissues. Mesenchymal - Muscle; bone; cartilage; tendon and Hematopietic - Blood cells; brain.
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
adult body cells have a function where as embryonic stem cells have no set function as of that stage. now there are some adult stem cells and those have little to no difference than embryonic stem cells
Only adult stem cells produce progenitor cells because they multiply though the process of cell division and therefore produce progenitor cells.
Pluripotent haematopoietic stem cells are the precusor/progenitor cells of all blood cells.

Stem cells are important cells found in all multi-celled organisms, that can divide and recognise problems. In mammals, there are two types of stem cells: embryonic cells, and adult stem cells, which are found in various tissues. In adult organisms, stem cells and progenitor cells act as a repair system for the body, renewing and restoring adult tissues.
Neurogenesis is a pre-natal process where neurons are created from the combination of the neural stem cells and the progenitor cells in a woman's womb.

An embryonic stem cell potentially can develop into ANY cell in the body theoretically without limit to replenish, and an adult stem cell is only able to mature into a specialised tissue cell from which tissue the cell is positioned.
