Explanation / Answer
1.
Stem cells are the undifferentiated or blank cells that are capable of self renewal. Stem cells divide to produce daughter cells, in which both may be similar to the parent stem cell, or one stem cell and another progenitor cell. During the first stages of our embryonic life, cells divide continuously without being specialised, because they are stem cells.
Progenitor cell is not stem cell, but it is a partially specialised cell. The daughter cells of progenitor cells divide and these daughter cells differentiate to specialised cells. For example, the progenitor cells of bone marrow give rise to more specialised blood cells of different types.
Stem cell research is beneficial from its theraoeutic applications point of view, as treatment with stem cells seems to be promising.
•Stem cell therapy is expected to provide the solution in the treatment of neurodegenerative diseases, diabetes, heart disease, and other conditions where organ regeneration or transplantation is needed.
•The use of differentiated cell lines to test new drugs on each cell type to examine possible interactions in vitro before performing in vivo studies is critical in the development of drugs. Having these cell lines available for research use will reduce the need for research animals.
•Stem cells can be used to repair or generate healthy and functioning specialized cells that can replace diseased or dysfunctional cells.
•It is similar to organ transplantation, but the treatment consists of transplantation of cells instead of organs.
•The most important potential application of human stem cells is the generation of cells and tissues that could be used for cell-based therapies.
•Stem cells, directed to differentiate into specific cell types, offer the possibility of a renewable source of replacement cells and tissues to treat diseases including macular degeneration, spinal cord injury, stroke, burns, heart disease, diabetes, osteoarthritis, and rheumatoid arthritis.
