Summary
Limbus stem cell transplantation is a key treatment for corneal defects. Other stem cells like epithelial, epidermal, and mesenchymal cells also promote corneal regeneration and healing.
Area of Science:
- Ophthalmology
- Regenerative Medicine
- Stem Cell Biology
Context:
- Corneal defect healing relies on limbus stem cells.
- Loss of limbus stem cells causes wound healing complications.
- Stem cell research presents novel therapeutic strategies for corneal regeneration.
Purpose:
- To review current and experimental stem cell therapies for corneal defects.
- To highlight the role of various stem cell types in corneal repair.
- To discuss the potential of stem cell transplantation in ophthalmology.
Summary:
- Autologous limbus stem cell transplantation is the primary treatment for corneal defects.
- Amniotic membrane transplantation with limbus stem cells is clinically validated.
- Experimental approaches include bone marrow-derived mesenchymal stem cells, epidermal stem cells, and adipose-derived stem cells for corneal healing.
- In vitro cultivated buccal mucosa epithelial cell transplantation has also been clinically tested.
Impact:
- Limbus stem cell failure limits autologous transplantation success.
- Epithelial, epidermal, and mesenchymal stem cells (bone marrow- or adipose-derived) are established treatments for corneal defects.
- Mesenchymal stem cells provide immunosuppressive and anti-inflammatory benefits, enhancing their therapeutic potential.

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.

01:19Clinical Applications of Epidermal Stem Cells
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own EpiSCs...
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.
01:17Stem 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...
