Summary
Restoring ocular surface defense is crucial before limbal stem cell transplantation for corneal diseases. Surgical options like grafts and amniotic membranes show promise for reconstructing the damaged ocular surface.
Area of Science:
- Ophthalmology
- Regenerative Medicine
- Stem Cell Biology
Context:
- Limbal stem cells in the basal corneal epithelium are vital for corneal regeneration.
- Diseases can impair these stem cells, leading to limbal stem cell deficiency.
- Effective therapeutic strategies are essential for managing this condition.
Purpose:
- To review current and emerging therapeutic strategies for limbal stem cell deficiency.
- To highlight the importance of ocular surface restoration prior to stem cell transplantation.
- To discuss surgical interventions and reconstructive approaches for the cornea.
Summary:
- Ocular surface defense and a stable tear film are prerequisites for successful stem cell transplantation.
- Surgical options include superficial keratectomy, amniotic membrane transplantation, conjunctival-limbal autografts, and keratolimbal allografts.
- Amniotic membrane serves as a biological substrate for reconstructing damaged corneal stroma, with promising results using bio-engineered limbal epithelium.
Impact:
- Establishes the critical need for pre-transplantation ocular surface optimization.
- Provides an overview of surgical interventions for corneal reconstruction in stem cell deficiency.
- Underscores the necessity for further research in patient selection and immunosuppression protocols for allograft survival.

Adult Stem Cells

Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously...

Embryonic Stem Cells
32.6K
Embryonic stem (ES) cells are undifferentiated pluripotent cells, meaning they can produce any cell type in the body. This gives them tremendous potential in science and medicine since they can generate specific cell types for use in research or to replace body cells lost due to damage or disease.

Embryonic Stem Cells

Embryonic stem (ES) cells were first discovered in mice in 1981 by Martin Evans. In 1998, James Thomson identified a method to isolate embryonic stem cells from humans. Human embryonic stem cells (hESCs) are obtained from 3-5 day old embryos that remain unused after an in vitro fertilization procedure.
ES cells are grown in a culture medium where they can divide indefinitely, creating ES cell lines. Under certain conditions, ES cells can differentiate, either spontaneously into a variety of...

Induced 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...

Distinctive Features of Adult Stem Cells vs Cancer Stem Cells

A stem cell is an unspecialized cell that can divide without limit as needed and can, under specific conditions, differentiate into specialized cells.
Adult stem cells
Adult stem cells are tissue-specific; hence, they divide to develop the tissue from which they originate. One type of adult stem cell is the epithelial stem cell, which gives rise to the keratinocytes in the multiple layers of epithelial cells in the epidermis of the skin. Adult bone marrow has three distinct types of stem cells:...

Stem 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...
