Hutchinson-Gilford Progeria Syndrome is a rare genetic disorder caused by a specific gene mutation, characterized by aging symptoms and managed by monitoring heart health and using low-dose aspirin.

Bioaesthetic therapies could improve healthcare if they safely regenerate cells, tissues, or organs to restore normal function.

The conclusion is that the cornea has two types of stem cells, with Lrig1+ cells being key for renewal in aging corneas, independent of CD44.

The cancer gene c-Myc increases harmful chemicals that damage DNA and can lead to cancer, but antioxidants can reduce this damage.

Vitamin D is crucial for skin health and managing skin diseases.

Different types of skin cells and immune cells play a role in healing UV-damaged skin, with chronic UV exposure causing lasting damage to certain skin cells.
