Stem cells were not invented by a specific person, but rather their existence was discovered through scientific research. In the 1960s and 1970s, scientists Ernest McCulloch and James Till demonstrated the presence of stem cells in bone marrow. Since then, stem cells have been extensively studied and their potential for medical treatments has been recognized.
The differentiation of stem cells is not limited to immature animals. Stem cells have the ability to differentiate into specialized cell types in both immature and mature animals. However, the potential and efficiency of differentiation may vary depending on the developmental stage and the specific type of stem cell. In general, embryonic stem cells have a greater capacity for differentiation compared to adult stem cells, which may have more limited potential to differentiate into specific cell lineages.
Stem cells have the potential to revolutionize medicine, but they cannot be used to prevent death. While they can differentiate into various cell types and potentially treat diseases, death is a natural part of the life cycle and cannot be prevented or reversed through stem cell therapy. However, stem cell research can help improve the quality of life and extend lifespan by treating certain medical conditions and developing regenerative therapies.
Yes, moringa plants have a stem. The stem is woody and upright, which gives the plant support and helps it grow vertically. The stem also serves as a conduit for water and nutrients between the roots and the rest of the plant.
Yes, stem cells are unspecialized cells that have the potential to develop into different types of specialized cells in the body. They can divide and replicate to produce more stem cells, or they can differentiate into specific cell types depending on the signals they receive from their environment.
The significance of being able to harvest stem cells that can specialize into any type of cell, known as pluripotent stem cells, is that they have the potential to be used in regenerative medicine to treat a wide range of diseases and injuries. These cells can be directed to differentiate into specific cell types and tissues, such as nerve cells or heart muscle cells, offering the potential for repairing damaged organs and tissues. This holds great promise for treating conditions that currently have limited or no treatment options.
Yes, patients with VP (ventriculoperitoneal) shunts can potentially receive intrathecal stem cell therapy. However, careful consideration and evaluation of the patient's condition and shunt function would be necessary to ensure the procedure is safe and appropriate. Consultation with a neurosurgeon and stem cell specialist would be recommended to determine the best course of action.
A morula (mulberry) is an early stage in the development of the embryo at which it consists of a solid spherical ball of apparently identical cells. The morula stage is when one of the earliest prenatal diagnostic test can be carried out, by removing a single cell (blastomere) and carrying out genetic diagnosis on its DNA. Each one could develop into a complete animal (or human) since they are genetic the same.
The biggest disadvantage of using unipotent stem cells for medical treatment is their limited differentiation potential. Unipotent stem cells can only differentiate into a specific type of cell, which restricts their ability to treat a wide range of conditions or injuries. This narrow differentiation capacity hinders their potential for regenerative medicine compared to pluripotent stem cells that can differentiate into various cell types.
Yes, it is possible to donate stem cells. There are two main methods to donate stem cells: 1) Peripheral blood stem cell donation, which involves extraction of cells from the bloodstream, and 2) Bone marrow donation, which requires a surgical procedure to collect cells from the hipbone. You can register as a donor through various organizations and potentially be matched with a patient in need.
If stem cells mature into erythrocytes (red blood cells), they will become specialized for oxygen transport in the body. Erythrocytes are responsible for carrying oxygen from the lungs to the rest of the tissues and organs, as well as removing carbon dioxide waste. They have a unique biconcave shape and lack a nucleus to maximize their capacity for oxygen-carrying.
Yes, adult stem cells have been used to treat a variety of conditions including certain types of cancer, immune disorders, blood disorders, and bone and cartilage diseases. Additionally, adult stem cells have shown promising results in the treatment of heart diseases and neurological disorders such as Parkinson's disease and spinal cord injuries.
explain the differences between elodea stem and dicot stem
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.
The erythrocyte (RBC), leukocyte (WBC) and the platelets are all formed in bone marrow. While the erythrocyte and leukocyte are produced from the hematopoietic stem cells, the platelets are are derived from fragmentation of precursor megakaryocytes.
There are many different cells in the human body. The different cells in the body are generally grouped into tissues that have similar properties. The four main groups of tissues in the body are, muscular, nervous, connective, and epithelial.
There are 3 classes of cells in the human body. Labile cells, stable cells, and permanent cells. Labile cells are dividing all the time--always in the cell cycle. Examples include cells in the digestive tract, skin, respiratory tract, and stem cells in the bone marrow producing blood cells. Stable cells are in Gap O most of the time in the cell cycle, but can be stimulated to enter the cell cycle when needed. Examples include: the liver, the proximal tubules of the kidney, and endocrine glands. Permanent cells remain in the Gap 0 phase of the cell cycle, and will not come out no matter what!!! RBC's, nervous tissue, cardiac myocytes, and the lens of the eye are examples. Permanent cells cannot be replaced!!
Catholics are COMPLETELY against stem cell research. Another Answer Catholics are completely against embryonic stem cell research, which is completely immoral because it involves harvesting and destroying human embryos - infants. Catholics support adult stem cell research, and Catholic physicians and geneticists are carrying it on right now. "Adult" this case is a term that means "already born". The source of these cells is often blood from newborn infants' placentas and umbilical cords, these used to be just thrown away as medical waste. This blood and tissue provides "adult" stem cells that can be used for this research. In fact, the most successful results transplanting stem cells have been of the "adult" type; none of the "embryonic" type has yet been successful.
They are not better, embryonic stem cells can become more types then adult.
Stem cells can be transformed into other types of cells and replace diseased cells in the body. For example, scientists are working on a way to replace nerve cells damaged by Parkinson's disease.
Adult stem cells have been used and are still being used to cure many ailments as research continues.
Embryonic stem cells have never been useful for anything do to issues of getting the cells to work. Adult stem cells, on the other hand, have been very useful is stem cell research.
