Summary
Mouse embryonic stem cell microvesicles (mESMVs) can reprogram Müller cells. These microvesicles induce de-differentiation and cell cycle re-entry, promoting retinal tissue regeneration.
Area of Science:
- Stem cell biology
- Developmental biology
- Ophthalmology
Background:
- Mouse embryonic stem cells (mESCs) release microvesicles (mESMVs) involved in cell-cell communication.
- These microvesicles can transfer contents to various cell types, including non-stem cells.
Purpose of the Study:
- To investigate if mESMVs act as signals for retinal progenitor Müller cells.
- To determine if mESMVs induce Müller cell de-differentiation and cell cycle re-entry.
- To assess if these processes lead to differentiation along retinal lineages.
Main Methods:
- Isolation and characterization of microvesicles from mouse embryonic stem cells.
- Co-culture of Müller cells with mESMVs.
- Analysis of Müller cell de-differentiation, cell cycle status, and differentiation markers.
Main Results:
- mESMVs were confirmed to induce de-differentiation in Müller cells.
- ESMV treatment led to Müller cells re-entering the cell cycle.
- The microenvironment was altered, becoming more permissive for tissue regeneration.
Conclusions:
- mESMVs are potent signaling agents capable of reprogramming Müller cells.
- These microvesicles facilitate retinal progenitor cell plasticity.
- mESMVs hold potential for promoting retinal tissue regeneration strategies.

3.4K
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...

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 (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...

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.

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...
