Neurogenesis and Regeneration of Nervous Tissue01:15

Neurogenesis and Regeneration of Nervous Tissue

669
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

Methods of Nuclear Reprogramming

1.8K
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...

Somatic to iPS Cell Reprogramming

2.1K
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...

Area of Science:

  • Biomaterials Science
  • Neuroscience
  • Regenerative Medicine

Background:

  • Oxygen and electron signaling are crucial for neural-cell fate and brain repair.
  • Clinical applications are limited by the short half-life and poor spatiotemporal control of oxygen and electrical signals.

Purpose of the Study:

  • To develop a wireless-charging, sustained oxygen-releasing conductive microgel (SOCO) for on-demand oxygen release and electrical stimulation.
  • To investigate the therapeutic potential of SOCO as an "electromagnetic messenger" for nerve regeneration in traumatic brain injury (TBI).

Main Methods:

  • Development of SOCO microgels for wireless charging and controlled oxygen release.
  • Application of alternating magnetic fields (AMF) to enhance oxygen release and provide electrical stimulation.
  • In vivo studies involving whole-brain analysis, spatial multiomics, and single-cell deconvolution.

Main Results:

  • SOCO effectively promoted nerve regeneration and reconstruction of blood vessels and neurons.
  • Treatment reduced glial scarring in TBI by modulating microglia and promoting new neuron infiltration.
  • Analysis revealed reprogramming of angiogenic markers and the GABAergic pathway, improving brain function and behavioral recovery.

Conclusions:

  • In situ catalytic SOCO with noncontact AMF acts as an "electromagnetic messenger" for TBI treatment.
  • This approach offers a novel therapeutic strategy for reprogramming neuro-regeneration and enhancing brain function recovery.
  • The technology addresses limitations in spatiotemporal control for oxygen and electrical stimulation in neural repair.
