Stem Cell Division

Stem cells are a type of cell that has the ability to divide and renew themselves for long periods. They are found in most tissues of the body and can give rise to specialized cells. Stem cells divide in one of two ways: symmetrically or asymmetrically. Symmetrical division results in two daughter cells that are…

Allogenic vs Autologous

Stem cells are undifferentiated cells that have the ability to develop into various specialized cell types. There are two main types of stem cells: allogenic stem cells and autologous stem cells. Allogenic stem cells come from a donor, such as a family member or an unrelated individual. They are typically obtained from bone marrow or…

How Are Stem Cells Grown?

Stem cells are the foundation cells for all the other cell types in our bodies. They can divide and renew themselves for long periods, and they can give rise to specialized cells with more specific functions. The ability of stem cells to divide and regenerate tissues has made them a valuable tool in the field…

What is a Clone

A clone is an identical copy of something. In the biological sense, it refers to an organism that has the same genetic makeup as another. Cloning in biotechnology refers to the process of creating genetically identical copies of cells or organisms. The idea of cloning has been around for a long time, but it was…

The Electron Microscope

The electron microscope is one of the most important tools in the scientific arsenal. It allows us to see things that are too small to be seen with the naked eye and to study them in great detail. The first electron microscope was built in 1931 by German physicist Ernst Ruska. He was awarded the…

Cell Death

Cell death is a process that occurs in all tissues and organs of the body. It is a normal and essential process for the maintenance of tissue homeostasis and the prevention of disease. There are two main types of cell death: programmed cell death, or apoptosis, and non-programmed cell death, or necrosis. Apoptosis is a…

Stem Cells and Inflammation

The potential of stem cells to modulate the inflammatory response has generated considerable interest in their therapeutic use in the treatment of inflammatory diseases. The ability of stem cells to home to sites of injury and modulate the local inflammatory response has been demonstrated in a number of studies. In addition, the use of stem…

Body Healing Process

The body is an amazing machine that is constantly working to heal itself. When we cut our finger, for example, the body immediately starts the process of repairing the damage. This is known as the inflammatory response, a vital part of the healing process. The first step in the inflammatory response is to increase blood…

Cytokines What Are They?

Cytokines are proteins that are secreted by cells in the immune system in response to a stimulus. They are important mediators of the immune response, and can be either pro-inflammatory or anti-inflammatory. Cytokines can be secreted by a variety of cells, including macrophages, T-cells, and B-cells. They are involved in a wide range of immune…
