Stem Cell Reviews and Reports
|May 26, 2011
Summary
Tendon-derived stem cells (TDSCs) are newly discovered cells within tendons. This review explores their characteristics, potential role in tendinopathy, and promising applications in tendon repair.
Area of Science:
- Biomedical Engineering
- Stem Cell Biology
- Orthopedics
Background:
- Tendons were traditionally believed to solely comprise tenocytes responsible for tissue maintenance and repair.
- Recent discoveries have identified tendon-derived stem cells (TDSCs) within tendon tissues, challenging this view.
- Understanding TDSCs is crucial for advancing tendon regenerative medicine.
Purpose of the Study:
- To review the in vitro characteristics of tendon-derived stem cells (TDSCs).
- To discuss the potential pathogenic role of TDSCs in tendinopathy development.
- To explore the therapeutic potential of TDSCs in tendon and tendon-bone junction repair.
Main Methods:
- Literature review summarizing current research on TDSC isolation, culture, and characterization.
- Analysis of studies investigating TDSC immunophenotypes, proliferation, differentiation, and senescence.
- Examination of evidence linking TDSC niche interactions to tendinopathy and repair processes.
Main Results:
- TDSCs exhibit distinct in vitro characteristics, including morphology, immunophenotype, and differentiation potential.
- The tendon niche influences TDSC behavior, potentially contributing to tendinopathy pathogenesis.
- TDSCs show promise as a cell source for enhancing tendon and tendon-bone junction repair.
Conclusions:
- TDSCs possess unique properties relevant to tendon biology and pathology.
- Further research into TDSC niche interactions is needed to elucidate their role in tendinopathy.
- TDSCs represent a promising therapeutic avenue for tendon regeneration and repair.

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.

01:17Stem 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...
01:19Mesenchymal Stem Cells
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 access...
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.
01:21Satellite Stem Cells and Muscular Dystrophy
Satellite stem cells or myosatellite cells are quiescent stem cells that Alexander Mauro first identified in 1961. These cells are located between the sarcolemma, the plasma membrane of muscle fibers, and the basal lamina, the connective tissue sheath covering it. These mononucleated cells are activated in response to muscle injury, can transform into myoblasts, and may form or repair muscle fibers. Myosatellite cells can provide additional myonuclei for muscle regeneration or return to a...
