Differentiation

Histological sections of the leg muscles without injury (left) and five days after it (center, right) in a control mouse and a transgenic mouse. It can be seen that the area of ​​the muscle fibers that develop after the injury is smaller in the transgenic mouse, which indicates a disturbance in the differentiation of the stem cells into muscle cells

overcome the damage

Researchers have discovered that two epigenetic events (removing and adding methyl from DNA) lead to the differentiation of stem cells into muscle cells and thus to the regeneration and healing of muscles after their injury
After the division of the simple model cell, one of the daughter cells inherits only one type of lipid (red) and most of the protein fragments (blue), while the other daughter cell inherits two types of lipids (red and green). Image: See link to the source of the image at the end of the article
