Stem Cell Culture

Stem 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...

Multipotency of Hematopoietic Stem Cells

Multipotency 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...

Embryonic Stem Cells

Embryonic 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...

Embryonic Stem Cells

Embryonic 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.

Induced Pluripotent Stem Cells

Induced 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...

Induced Pluripotent Stem Cells

Induced 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).
Somatic cells are...

Summary

Generating diverse neurons from a single cell is complex. Replacing adult neurons is challenging, but using neural stem cell (NSC) factors to protect existing neurons offers a promising therapeutic avenue.

Background:

The generation of diverse neuronal populations from a single fertilized cell is a long-standing question in biology.
Historical methods like histology and modern techniques like genetic sequencing have elucidated neuronal development.
Neural stem cells (NSCs) produce specific neuronal classes through sequential gene expression and molecular interactions.

Observation:

Postmitotic neurons arise in a specific temporal and spatial sequence from germinal cells.
Dividing cell subtypes and their locations in ventricular and subventricular zones have been identified.
Recent advances reveal molecular mechanisms driving NSC heterogeneity and neuronal class specification.

Findings:

Neuronal development is a highly regulated process with limited tolerance for in vivo deviation.
Replacing adult neurons in pathological conditions presents significant challenges.
Leveraging trophic factors from NSCs or their derivatives may offer a feasible strategy to mitigate neuronal degeneration.

Implications:

Understanding precise neuronal development is crucial for regenerative medicine.
Therapeutic strategies may focus on neuroprotection rather than direct cell replacement.
NSC-derived factors hold potential for treating neurodegenerative diseases.
