Summary
Rhesus monkey embryonic stem cells (ESCs) cultured in a 3D collagen matrix formed gland-like structures and differentiated into neural, epithelial, and endothelial cells. The micro-environment, influenced by feeder cells, is critical for stem cell behavior and differentiation.
Area of Science:
- Stem cell biology
- Developmental biology
- Biomaterials science
Background:
- Embryonic stem cells (ESCs) differentiation is crucial for regenerative medicine.
- Three-dimensional (3D) culture systems offer a more physiologically relevant environment for stem cell research.
- Understanding the role of the micro-environment in stem cell behavior is essential for optimizing culture conditions.
Purpose of the Study:
- To analyze the production of extracellular matrix (ECM) proteins and cell adhesion molecules by differentiating rhesus monkey ESCs in a 3D collagen matrix.
- To investigate the influence of human neonatal foreskin fibroblasts (HPI.1) on the ESC-derived micro-environment.
- To determine the critical factors within the 3D micro-environment that direct ESC growth and differentiation.
Main Methods:
- Rhesus monkey ESCs (R366.4) were cultured on or embedded within a 3D collagen matrix, with or without HPI.1 feeder cells.
- Analysis of endogenous ECM proteins, cell-cell adhesion molecules, cell-surface receptors, lectins, and glycoligands produced by differentiating ESCs.
- Assessment of the impact of HPI.1 cells on the expression of these molecules.
Main Results:
- ESCs formed complex tubular and spherical gland-like structures in the 3D collagen matrix.
- Differentiated ESCs exhibited phenotypes characteristic of neural, epithelial, and endothelial lineages.
- The expression of several ECM and cell adhesion molecules was modulated by HPI.1 feeder cells, while others remained unaffected.
- The ESC-derived micro-environment, influenced by feeder cells and soluble factors, played a significant role in cell behavior.
Conclusions:
- A 3D collagen matrix, modulated by feeder cells and ESCs, can create a niche that positively influences stem cell behavior and differentiation.
- Both soluble factors and the physical niche are critical for directing ESC growth and differentiation in 3D culture.
- This 3D culture system provides a potential template for developmental biology studies and stem cell differentiation research.

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...

01:22iPS 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.
01:17Stem 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...
01:10Zygotic Development And Stem Cell Formation
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...
01:26Stem Cell Niche
The stem cell niche is the dynamic microenvironment where stem cells reside. Inside these niches, the cells may remain undifferentiated, undergo high self-renewal, or become lineage-specific progenitors. Stem cells coexist with other niche cells, such as stromal cells. They also interact closely with the ECM. Cell-cell and cell-matrix communication occur via adhesion molecules or soluble factors that signal the stem cells and determine their fate. Stromal cells also provide survival signals to...
