A bioengineered living cell construct activates metallothionein/zinc/MMP8 and inhibits TGFβ to stimulate remodeling of fibrotic venous leg ulcers.

What Was Tested

Researchers studied Vitamin D, K2, Magnesium and Zinc in this randomized controlled trial publication.

Venous leg ulcers (VLU) represent a major clinical unmet need, impairing quality of life for millions worldwide.

Previously, the researchers reported a BLCC-mediated acute wounding response at the ulcer edge; in this study the researchers elucidated the BLCC-specific effects on the epidermis-free ulcer bed.

Who Took Part

The study group was 30 subjects.

PubMed indexes the participants as adults, middle-aged adults, older adults and people over 80, both men and women.

How the Study Was Run

The researchers set it up as a randomized study.

Because people in this Vitamin D, K2, Magnesium and Zinc study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

What Was Measured

The subject headings attached to it are Collagen, Compression Bandages, Decorin, Fibrosis, Gene Expression Profiling, Inflammation and Matrix Metalloproteinase 8.

What This Means in Plain Language

The paper is a randomized study of Vitamin D, K2, Magnesium and Zinc in 30 subjects.

With fewer than 40 people, it is a small study, so it is better read as an early signal for further research than as a settled answer.

The publication is from 2020 (Wound repair and regeneration : official publication of the Wound Healing Society [and] the European Tissue Repair Society), a journal based in United States.
