Summary
Identifying the niche for human trophoblast stem cells is crucial for studying pregnancy complications. This research explores potential locations for these stem cells in the human placenta to enable their derivation and advance placental biology.
Area of Science:
- Reproductive biology
- Developmental biology
- Cell biology
Background:
- Abnormal trophoblast differentiation causes pregnancy complications like preeclampsia and fetal growth restriction.
- Studying human trophoblast differentiation is hindered by the absence of a stem cell model.
- Mouse trophoblast stem cells have been derived, but human equivalents remain elusive.
Purpose of the Study:
- To explore potential niches for human trophoblast stem cells within the placenta.
- To facilitate the derivation and in vitro establishment of human trophoblast stem cells.
- To advance the understanding and treatment of placental disorders.
Main Methods:
- Literature review and analysis of existing data on trophoblast stem cell niches.
- Comparative analysis of mouse and human placental development.
- Hypothesizing potential locations for human trophoblast stem cells.
Main Results:
- Several potential niches for human trophoblast stem cells are proposed within the human placenta.
- Evidence suggests these cells may reside in the villous cytotrophoblast layer or non-trophoblast placental portions.
- The pre-implantation blastocyst is also considered as a potential niche.
Conclusions:
- Identifying the trophoblast stem cell niche is key to deriving human stem cells.
- Established human trophoblast stem cell lines will enable research into placental disease pathophysiology.
- These cell lines will aid in discovering diagnostic biomarkers and therapeutic targets for pregnancy complications.

01:10Zygotic Development And Stem Cell Formation
7.1K
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...

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...

01:27Source And Potency Of Stem Cells
6.5K
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
4.0K
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...

01:13Induced Pluripotent Stem Cells
28.3K
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...
