Summary
Mesenchymal stem cells (MSCs) are more abundant in keloid tissue than normal skin. Recurrent keloids show significantly higher MSCs, suggesting a link between MSCs and keloid severity and recurrence.
Area of Science:
- Dermatology
- Regenerative Medicine
- Cell Biology
Background:
- Mesenchymal stem cells (MSCs) are hypothesized as precursors for fibroblasts and myofibroblasts in keloids.
- MSCs may represent a regenerative pool contributing to keloid formation.
Purpose of the Study:
- To investigate the presence and density of MSCs in keloid tissue.
- To determine if MSC levels correlate with keloid recurrence.
Main Methods:
- A longitudinal prospective study comparing MSCs in keloid specimens and normal skin controls.
- Statistical analysis included Student's t-test, chi-squared, and Fisher's exact tests.
Main Results:
- Recurrent keloids exhibited a higher mean MSC density (841.4 MSCs/g) compared to non-recurrent keloids (578 MSCs/g) and normal skin (580 MSCs/g).
- Keloid tissue generally showed a higher percentage of MSCs than normal skin.
Conclusions:
- MSCs are present in higher percentages in keloids compared to normal skin.
- Elevated MSC counts in recurrent keloids suggest a correlation with keloid disease severity and recurrence potential.

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...

2.7K
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...

5.2K
The stem cell niche is the dynamic microenvironment where stem cells reside. Inside these niches, the cells may remain undifferentiated, undergo high self-renewal, or become lineage-specific progenitors. Stem cells coexist with other niche cells, such as stromal cells. They also interact closely with the ECM. Cell-cell and cell-matrix communication occur via adhesion molecules or soluble factors that signal the stem cells and determine their fate. Stromal cells also provide survival signals to...
