Stem cell
Stem cells are unique cells in the body with the remarkable potential to develop into many different cell types during early life and growth. They can divide and produce more stem cells (self-renewal) or differentiate into specialized cells, such as muscle cells, red blood cells, or brain cells.
There are several types of stem cells, including:
Embryonic Stem Cells
Induced Pluripotent Stem Cells (iPSCs)
Embryonic Stem Cells
Derived from early-stage embryos and are pluripotent, meaning they can develop into almost any cell type in the body.
Adult Stem Cells
Induced Pluripotent Stem Cells (iPSCs)
Embryonic Stem Cells
Found in various tissues like bone marrow and the brain. They are multipotent, meaning they are limited to differentiating into a narrower range of cell types related to their tissue of origin.
Induced Pluripotent Stem Cells (iPSCs)
Induced Pluripotent Stem Cells (iPSCs)
Induced Pluripotent Stem Cells (iPSCs)
Adult cells that have been genetically reprogrammed to an embryonic stem cell-like state, thus gaining the ability to differentiate into various cell types.
Stem cells are vital in medical research and therapy because of their ability to regenerate and repair damaged tissues. They hold potential for treating a wide range of diseases and conditions, including spinal cord injuries, Parkinson's disease, and diabetes.
Stem cells are used in a wide range of medical applications, primarily due to their unique ability to regenerate and repair damaged tissues, as well as their potential to develop into different types of cells.
Here are some of the key uses of stem cells:

- Bone Marrow Transplants: Hematopoietic stem cells (a type of adult stem cell) from bone marrow or blood are used to treat blood disorders like leukemia, lymphoma, and multiple myeloma. These stem cells can regenerate the entire blood and immune system.

- Repair of Damaged Tissues: Stem cells are being used in research and clinical trials to repair tissues damaged by disease or injury. For example, researchers are exploring the use of stem cells to repair heart tissue after a heart attack, to regenerate bone in patients with bone injuries, and to restore cartilage in people with osteoarthritis.

Mesenchymal stem cells (MSCs)
What is Mesenchymal stem cells (MSCs)?
Mesenchymal stem cells (MSCs) are a type of adult stem cell found in various tissues, including bone marrow, fat (adipose tissue), umbilical cord blood, and more. They are multipotent, meaning they can differentiate into a limited range of cell types, specifically those that make up the musculoskeletal system, such as bone cells (osteoblasts), cartilage cells (chondrocytes), and fat cells (adipocytes).
Key Characteristics of MSCs:
