Summary
Stem cell-derived neurons offer insights into brain research but may yield artifacts. Integrating this data with human genetics and postmortem brain data via Convergent Functional Genomics validates findings.
Area of Science:
- Neuroscience
- Genomics
- Stem Cell Biology
Background:
- Stem cell technologies allow transcriptome analysis in patient-specific neuronal-like cells, relevant for brain research.
- In vitro culture of these cells may introduce artifacts and noise, potentially limiting their direct applicability.
Purpose of the Study:
- To propose and exemplify a Convergent Functional Genomics (CFG) approach to validate stem cell-derived neuronal data.
- To integrate and cross-validate findings from neuronal stem cells with independent data sources.
Main Methods:
- Utilizing stem cell-derived neuronal cells to access patient transcriptomes.
- Applying a Convergent Functional Genomics strategy.
- Integrating data from human genetic studies, postmortem human brain samples, and animal models.
Main Results:
- The CFG approach allows for the prioritization and validation of findings from stem cell-derived neuronal data.
- Cross-validation with independent datasets enhances the reliability of neuronal cell transcriptome studies.
Conclusions:
- Convergent Functional Genomics provides a robust framework for validating stem cell-derived neuronal data.
- This integrated approach mitigates concerns about in vitro artifacts, increasing the relevance of stem cell-based brain 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...
01:26Stem 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...
01:13Induced Pluripotent Stem Cells
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 called induced pluripotent stem...
01:06Induced Pluripotent Stem Cells
Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

01:01Regulation of Hematopoietic Stem Cells
All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...
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...
