New Research Reveals Astrocytes Can Transform into Brain Stem Cells

Epigenetic changes triggered by lack of blood supply enable astrocytes to generate new neurons, offering potential for regenerative medicine.

Astrocytes, typically supportive brain cells, can be reprogrammed into brain stem cells through DNA methylation changes.
This transformation is activated by a lack of blood supply, such as during a stroke, leading to the formation of new nerve cells.
Researchers identified unique methylation patterns that distinguish brain stem cells from ordinary astrocytes.
The findings suggest new therapeutic approaches to stimulate neuron production and repair brain damage.
The study, conducted on mice, highlights the potential for enhancing brain self-healing after injuries.
