Summary
Direct lineage reprogramming allows cells to change identity without dividing, challenging traditional views. New technologies help understand the complex cellular journey and decisions involved in this identity transition.
Area of Science:
- Cell Biology
- Developmental Biology
- Stem Cell Biology
Background:
- Direct lineage reprogramming alters traditional understanding of cellular identity.
- Unlike natural differentiation, identity changes can occur without cell division (mitosis).
Purpose of the Study:
- To discuss emerging concepts on the nature of transitory states during direct lineage reprogramming.
- To explore the challenges and cellular decisions involved in achieving a new cell fate.
Main Methods:
- Review of recent technological advancements for deconstructing cellular and molecular processes.
- Analysis of conceptual frameworks regarding cell identity transitions.
Main Results:
- Direct lineage reprogramming involves unique transitory states not seen in natural differentiation.
- Cells navigate complex challenges and make critical decisions to attain a new identity.
Conclusions:
- Direct lineage reprogramming offers a novel paradigm for studying cell identity acquisition.
- Understanding these transitory states is crucial for advancing regenerative medicine and cell therapy.

2.4K
Reprogramming alters the gene expression in somatic cells, transforming them into induced pluripotent stem (iPS) cells over several generations. Scientists can reprogram cells by introducing genes for four transcription factors—Oct4, Sox2, Klf4, and c-Myc (OSKM) by viral or non-viral methods. These factors are also known as Yamanaka factors after Shinya Yamanaka, who first generated iPS cells using mouse skin cells. Yamanaka was awarded the Nobel Prize in Physiology or Medicine in 2012...

01:14Introduction to Nuclear Reprogramming
2.1K
Nuclear reprogramming is the process of switching gene expression of one cell type to that of another cell type, usually from a differentiated cell state to an undifferentiated cell state. Differentiation occurs during processes such as development and morphogenesis, tissue regeneration, and malignancy. Cells can also be artificially induced to reprogram their gene expression by techniques such as nuclear transfer, induced pluripotency, and cell fusion. Such techniques have many applications in...

01:24Methods of Nuclear Reprogramming
1.9K
Nuclear reprogramming is a process of transforming one cell type into an unrelated cell type by epigenetic changes that alter the cell’s original gene expression pattern. Such epigenetic changes force cells to express a different set of genes, which play a significant role in inducing transformation into other cell types. Nuclear reprogramming offers applications in reproductive cloning for livestock propagation and regenerative medicine — developing patient-specific cells for...

2.1K
Transdifferentiation, also known as lineage reprogramming, was first discovered by Selman and Kafatos in 1974 in silkmoths. They observed that the moths’ cuticle-producing cells transformed into salt-producing cells. Many such cases of natural transdifferentiation occur in organisms. In humans, pancreatic alpha cells can become beta cells. In newts, the loss of the eye’s lens causes the pigmented epithelial cells to transdifferentiate into the lens cells.

How does a complex organism such as a human develop from a single cell? It all starts from a single fertilized egg which gives rise to a vast array of cell types, such as nerve cells, muscle cells, and epithelial cells that characterize the adult? Throughout development and adulthood, cellular differentiation leads cells to assume their final morphology and physiology. Differentiation is the process by which unspecialized cells become specialized to carry out distinct functions.
