Scientists found a way on how to slow aging by directly reprogramming human cells. Using the young and old patients' skin cells called fibroblasts, the Salk researchers successfully created blood vessel cells that retain their age molecules.
The second one is the smooth muscle cells that cover the endothelial cells.
"We are among the first to use this technique to study the aging of the vascular system," said Roberta Schulte, the study's co-first author, and the Hetzer lab coordinator.
She added that the idea of using fibroblasts to create both of the cell types already existed, and they just adjusted the process according to their needs.
The study used the skin cells extracted from three old donors, aged 62 to 87 years old, three younger donors, 19 to 30 years old, and eight patients with Hutch Hutchinson-Gilford progeria syndrome (HGPS), a disorder commonly used to study aging.
