Summary
Bone marrow mesenchymal stem cells (MSC) support hematopoietic stem cells (HSC) and possess immunomodulatory and regenerative properties. Their safety and ease of expansion make them promising for various clinical applications, especially in HSC transplantation.
Area of Science:
- Stem Cell Biology
- Immunology
- Regenerative Medicine
Background:
- Mesenchymal stromal/stem cells (MSC) from bone marrow (BM) create a niche for hematopoietic stem cells (HSC).
- MSC can differentiate into bone, fat, and cartilage.
- MSC exhibit low immunogenicity and modulate immune responses.
Purpose of the Study:
- To review the potential of bone marrow-derived MSC in clinical applications.
- To highlight MSC's role in tissue regeneration and immune modulation.
- To assess MSC's suitability for hematopoietic stem cell transplantation.
Main Methods:
- In vitro and in vivo studies were analyzed.
- Clinical trial data on MSC safety and efficacy were reviewed.
- MSC properties including differentiation, immunomodulation, and tissue homing were examined.
Main Results:
- MSC demonstrate broad differentiation potential and ability to home to damaged tissues.
- MSC possess significant immunomodulatory and immunosuppressive capabilities.
- MSC have shown a strong safety profile in various clinical trials.
Conclusions:
- Bone marrow MSC are promising for treating conditions like myocardial infarction and diabetes.
- MSC are particularly advanced for use in HSC transplantation, aiding engraftment and preventing graft-versus-host disease.
- The ease of MSC isolation, expansion, and safety profile supports their continued investigation in clinical settings.

01:19Multipotency of Hematopoietic Stem Cells
The hematopoietic stem cells or HSCs are multipotent, meaning they can differentiate and give rise to all blood and immune cells. HSCs are maintained in the quiescent stage until an external stimulus initiates their differentiation. The multipotent HSCs exist as two heterogeneous populations, long-term repopulating cells (LTRC) and short-term repopulating cells (STRC). The two HSC populations have different surface markers or receptors and are classified based on quiescence and long-term...
01:19Mesenchymal Stem Cells
Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their access...
01:21Stem Cell Therapy for Tissue Regeneration
Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.

01:01Regulation of Hematopoietic Stem Cells
All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...
01:22Bone Marrow Sampling and Transplants
Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy the...

01:21Hematopoiesis
The process of blood cell formation is called hematopoiesis. Hematopoiesis starts early during development, on the seventh day of embryogenesis. This phase of hematopoiesis is called the primitive wave, wherein the extraembryonic yolk sac allows the production of erythroid cells and endothelial cells from a common precursor called hemangioblast. The erythroid cells provide oxygen to support the growth of the rapidly dividing embryo. Hemangioblasts later develop into hematopoietic stem cells or...
