Summary
Peripheral blood stem cells (PBSCs) are diverse and can be categorized into seven main groups. Understanding these populations is key to their clinical use, particularly in ophthalmology.
Area of Science:
- Stem cell biology
- Hematology
- Regenerative medicine
Background:
- Peripheral blood stem cells (PBSCs) represent a small fraction of peripheral blood cells.
- These cells are recognized for their heterogeneity and potential clinical applications.
- The precise number and classification of distinct PBSC populations remain unclear.
Purpose of the Study:
- To review and categorize the known populations of peripheral blood stem cells.
- To elucidate the major characteristics of these stem and progenitor cell types.
- To explore the potential applications of these PBSC populations, with a focus on ophthalmology.
Main Methods:
- Literature review and mini-review approach.
- Categorization of PBSCs into seven distinct groups based on current research.
- Analysis of the major characteristics and potential applications of each group.
Main Results:
- Peripheral blood stem cells (PBSCs) are classified into seven groups: hematopoietic stem cells (HSCs), CD34- stem cells, CD14+ stem cells, mesenchymal stem cells (MSCs), very small embryonic-like (VSEL) stem cells, endothelial progenitor cells (EPCs), and other pluripotent stem cells.
- The review highlights the overlapping and sometimes differently named nature of these cell populations.
- Key characteristics and potential therapeutic uses, especially in ophthalmology, are discussed for each category.
Conclusions:
- Peripheral blood stem cells (PBSCs) encompass a heterogeneous group of cell populations with significant clinical potential.
- A standardized classification into seven groups aids in understanding their distinct properties.
- Further research into these PBSC populations may unlock novel therapeutic strategies, particularly in treating ocular diseases.

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...
01:17Stem Cell Culture
Stem cell research aims to find ways to use stem cells to regenerate and repair cellular damage. Over time, most adult cells undergo the wear and tear of aging and lose their ability to divide and repair themselves. Stem cells do not display a particular morphology or function. Adult stem cells, which exist as a small subset of cells in most tissues, keep dividing and can differentiate into a number of specialized cells generally formed by that tissue. These cells enable the body to renew and...
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...
01:22iPS Cell Differentiation
The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.
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...

01:13Induced Pluripotent Stem Cells
Stem cells are undifferentiated cells that divide and produce different types of cells. Ordinarily, cells that have differentiated into a specific cell type are post-mitotic—that is, they no longer divide. However, scientists have found a way to reprogram these mature cells so that they “de-differentiate” and return to an unspecialized, proliferative state. These cells are also pluripotent like embryonic stem cells—able to produce all cell types—and are therefore called induced pluripotent stem...
