Summary
Trophoblast stem cells (TSCs) show self-renewal and multipotency, differentiating into various cell types. In utero administration of TSCs enables engraftment and differentiation into lung, heart, and retinal cells in developing mice.
Area of Science:
- Stem cell biology
- Developmental biology
- Regenerative medicine
Background:
- Tissue repair is often impaired in disease, necessitating novel therapeutic strategies.
- Cellular therapeutics offer potential for tissue regeneration.
- Trophoblast stem cells (TSCs) are investigated for their stem/progenitor cell properties.
Purpose of the Study:
- To determine if Trophoblast stem cells (TSCs) possess stem/progenitor cell characteristics.
- To assess the self-renewal and differentiation capacity of TSCs in vitro and in vivo.
- To explore the therapeutic potential of TSCs for tissue regeneration.
Main Methods:
- Isolation of CD117+ TSCs from embryonic day 18.5 murine placentas.
- In vitro culture of TSCs for self-renewal and differentiation assays.
- In utero injection of TSCs into fetal organs (lung, heart, retina) followed by histological assessment.
Main Results:
- CD117+ TSCs exhibited self-renewal in vitro, forming multicellular clones.
- TSCs demonstrated multipotency, differentiating into lung epithelial, cardiomyocyte, and retinal photoreceptor cells.
- In utero injected TSCs engrafted and differentiated into organ-specific cell types in developing mice.
Conclusions:
- CD117+ TSCs possess key stem cell properties: clonogenicity, self-renewal, and multipotency.
- In utero administration of TSCs leads to successful engraftment and differentiation into resident cells of the lung, heart, and retina.
- These findings support the potential of TSCs as a therapeutic tool for regenerative medicine.

5.9K
Stem cells are undifferentiated cells with extensive self-renewal properties that help them maintain their population during the fetal and adult stages of life. They can specialize in all cell types of the human body. However, their differential potential may vary and can be classified into five types. Stem cells can be (1) Totipotent, (2) Pluripotent, (3) Multipotent, (4) Oligopotent, and (5) Unipotent. Each stem cell has a specific origin; the fertilized egg or zygote is a totipotent cell and...

01:19Multipotency of Hematopoietic Stem Cells
3.7K
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...

01:10Zygotic Development And Stem Cell Formation
6.3K
The development of all multicellular organisms starts with the fusion of haploid cells called sperm and egg to form a diploid zygote. A zygote is a totipotent cell that can develop into a complete organism. The zygote undergoes cell division or cleavage to form an 8-cell mass. Until this stage, the cells are spherical, loosely attached, and remain totipotent. Totipotent cells are capable of developing both the embryonic and the extraembryonic tissues. However, as they continue to divide, they...
