Summary
Researchers review methods for deriving hematopoietic cells from embryonic stem cells (ESCs). Mimicking the hematopoietic niche in vitro shows promise, but efficiency and functionality of derived hematopoietic stem cells (HSCs) require further investigation.
Area of Science:
- Stem cell biology
- Hematopoiesis research
- Regenerative medicine
Background:
- Embryonic stem cells (ESCs) offer a potential source for hematopoietic cell generation.
- Hematopoiesis, the process of blood cell formation, is complex and tightly regulated.
- Current in vitro methods aim to recapitulate developmental processes for therapeutic applications.
Purpose of the Study:
- To review existing methodologies for deriving hematopoietic cells from ESCs.
- To evaluate strategies that mimic the in vitro hematopoietic niche.
- To identify challenges and future directions in ESC-derived hematopoiesis.
Main Methods:
- Review of literature on ESC differentiation protocols.
- Analysis of in vitro hematopoietic niche models using feeder cells, growth factors, and matrices.
- Assessment of methods for generating hematopoietic stem cells (HSCs), progenitors, and mature cells.
Main Results:
- Evidence supports the derivation of HSCs, committed progenitors, and mature hematopoietic cells from ESCs.
- In vitro hematopoietic niche mimicry using supportive cells, factors, and matrices is a key strategy.
- Successful derivation of functional hematopoietic cells from ESCs has been demonstrated.
Conclusions:
- Deriving hematopoietic cells from ESCs is feasible through in vitro niche mimicry.
- Further optimization is needed to improve the efficiency of HSC derivation.
- Ensuring the proper functionality of in vitro derived HSCs remains a critical area for research.

01:19Multipotency of Hematopoietic Stem Cells
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...
01:21Hematopoiesis
The process of blood cell formation is called hematopoiesis. Hematopoiesis starts early during development, on the seventh day of embryogenesis. This phase of hematopoiesis is called the primitive wave, wherein the extraembryonic yolk sac allows the production of erythroid cells and endothelial cells from a common precursor called hemangioblast. The erythroid cells provide oxygen to support the growth of the rapidly dividing embryo. Hemangioblasts later develop into hematopoietic stem cells or...
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...
00:58Embryonic Stem Cells
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.
00:57Embryonic Stem Cells
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
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...
