Summary
Researchers isolated tendon-derived stem cells (TDSCs) from heritage-breed turkeys. These turkey TDSCs show potential for regenerative medicine and tendon tissue engineering applications.
Area of Science:
- Regenerative Medicine
- Stem Cell Biology
- Animal Models
Background:
- Tendon injuries are common and severe, necessitating effective functional recovery strategies.
- Stem cells offer regenerative potential, but turkey-specific stem cells remain uninvestigated.
- Turkeys are a potential new large animal model for flexor tendon research.
Purpose of the Study:
- To isolate and verify tendon-derived stem cells (TDSCs) from heritage-breed turkeys.
- To characterize the stemness properties and differentiation potential of turkey TDSCs.
- To establish a foundation for using turkey TDSCs in tendon tissue engineering.
Main Methods:
- Isolation of nucleated cells from turkey flexor tendons.
- Culture of cells to assess clonogenicity, proliferation, and trilineage differentiation.
- Flow cytometry for surface antigen expression (CD90, CD105, CD44, CD45).
- Quantitative gene expression analysis of tenogenic markers and stemness factors (PouV, Nanog, Sox2).
Main Results:
- Approximately 4% of nucleated cells exhibited clonogenicity and high proliferation.
- Induced differentiation into multiple lineages was observed.
- TDSCs expressed key stem cell markers (CD90, CD105, CD44) and tenogenic markers (mohawk, collagen type I, tenascin C, elastin).
- Expression of stemness-regulating transcription factors (PouV, Nanog, Sox2) was confirmed.
Conclusions:
- Successful isolation and verification of turkey tendon-derived stem cells (TDSCs).
- Turkey TDSCs possess characteristics of multipotent stem cells with tenogenic potential.
- These findings support the use of turkeys as a novel animal model for tendon research and regenerative medicine.

01:19Multipotency of Hematopoietic Stem Cells
3.9K
The hematopoietic stem cells or HSCs are multipotent, meaning they can differentiate and give rise to all blood and immune cells. HSCs are maintained in the quiescent stage until an external stimulus initiates their differentiation. The multipotent HSCs exist as two heterogeneous populations, long-term repopulating cells (LTRC) and short-term repopulating cells (STRC). The two HSC populations have different surface markers or receptors and are classified based on quiescence and long-term...

A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...

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 (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...

28.1K
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...
